High Solids Methylated Melamine resins
Highly Methylated Melamine resins
Highly methylated melamine resins consist ofcommercial versions of hexamethoxymethylme­lamine(HMMM). They differ primarily in their degree ofalkylation and monomer content. All are efficient
crosslinking agents for hydroxyl, carboxyl and amide
functional polymers. The practical equivalent weightfor most of the resins is 130-180. Advantages are low
VOCs, high film flexibility and toughness (when usedwith inherently flexible backbone resins), excellent
formulation stability (especially in waterborne systems
formulated at a pH of 8-9), good mar resistance andgood intercoat adhesion properties. As typical withmelamine resins, all are low in color and color
development, have excellent exterior durability andgood heat resistance. Due to their high extent of

alkylation, the resins in this series require the additionof a strong acid catalyst for acceptable cure responsewhen baked at 125-150°C. Typically, 0.2- 0.4%
p-toluene sulfonic acid based on total binder solids
is recommended. The optimum concentration ofacid catalyst depends on the basicity of the othercomponents in the formulation and should bedetermined experimentally. Using a blocking amine
for the acid catalyst and adding a stabilizing alcohol to
the formulation can enhance formulation stability.
Methylated High Imino Melamine resins
Methylated high imino melamine resins are partiallymethylolated and highly alkylated. These characte­
ristics result in resins containing a significant
concentration of alkoxy/imino or high NH functio­nality.

The advantages are fast cure response at 120-150°C
without the need for strong acid catalysts, fast cureresponse in waterborne formulations, high film
hardness and low formaldehyde release on cure. In
addition to reacting with hydroxyl, carboxyl and amide
functionality on polymers, these resins also selfcondense readily. Therefore, their practical equivalentweight is typically 180-240. In addition, they can bestabilized by adding tertiary amine and stabilizing
primary alcohol to the formulation. Compared to theirhighly alkylated counterparts, the imino resins usually
result in slightly less flexible coatings and slightly
higher VOCs when used in solvent-based systems.

methylolated and partially alkylated. They cure wellat 125-150°C without the need to add a strong acidcatalyst. The acidity of most polymers used inthermoset coatings is sufficient to catalyze theirreaction and their film performance properties are
similar to those of the high imino resins mentioned
in the previous category. In addition to reacting withthe hydroxyl, carboxyl and amide functionality ofpolymers they also can self-condense readily.
Their practical equivalent weight is also 180-240.
As with all melamine resins, they can be stabilized
by adding amine and stabilizing alcohol to theformulation. The major limitation of these products
is high formaldehyde release on baking primarily
due to their high free methylol content.

High Solids Mixed Ether Melamine resins
Highly Alkylated Melamine resins
The highly alkylated melamine resins in thiscategory are similar to the commercial versions ofhexamethoxymethylmelamine (HMMM) except for
the type of alkylation alcohol. The resins containcombinations of methoxy sites and longer chain length
alkoxy sites (ethoxy, n-butoxy or iso-butoxy). They also
differ from each other in their degree of alkylation andmonomer content. Longer chain length alkoxy sites
impart lower viscosity, improved flow and leveling andintercoat adhesion. All of the resins in the series are
efficient crosslinking agents for hydroxyl, carboxyl andamide functional polymers. The practical equivalentweight for most is 140-200. Other advantages are low
VOCs, high film flexibility and toughness when usedwith inherently flexible backbone resins and excellent
formulation stability (especially in waterborne system
at a pH of 8-9 and good mar resistance properties).
Due to their high extent of alkylation, the resins in thisseries require the addition of a strong acid catalyst for

Typically, 0.2-0.4% p-toluene sulfonic acid based on

Butylated Melamine resins
Highly n-Butylated Melamine resins
Highly butylated melamine resins are similar to thecommercial versions of hexamethoxymethyl­melamine(HMMM), except they are n-butylated.
They also are slightly more oligomeric than their
methylated counterparts. The butylation or butoxysites impart improved flow, leveling and intercoat
adhesion properties. However, cure response is slower
than that of the resins in the methylated category. Yet,highly butylated melamine resins are efficient
crosslinking agents for hydroxyl, carboxyl and amide
functional polymers. The practical equivalent weight is160-220. Other advantages are high film flexibility andtoughness when used with inherently flexible
backbone resins, excellent formulation stability andgood mar resistance properties. Due to their highextent of alkylation, the resins require the addition ofa strong acid catalyst for acceptable cure responsewhen baked at 125-150°C. Typically 0.2-0.4% p-toluene
sulfonic acid based on total binder solids is necessary.
The optimum concentration of acid catalyst depends

The use of a blocking amine for the acid catalyst andthe addition of a stabilizing alcohol to the formulation
should enhance formulation stability.
n-Butylated Melamine resins
n-butylated resins in this category are very polymericin nature. They differ in extent of methylolation,butylation and polymerization. In general, higher
extents of methylolation and butylation result in morehydrophobic resins with lower viscosities, higher
stability, slightly higher film flexibility, film gloss andadhesion but slower cure response. Higher extentsof polymerization result in faster film property
development but also in higher viscosities andtherefore higher VOCs. None of the resins in thiscategory require the addition of a strong acid catalyst
for adequate cure at 125-150°C. Usually, the acidityof the other resin components in the formulation
results in sufficient catalysis. In addition to reactingwith hydroxyl, carboxyl and amide functionalities on
polymers, these resins self-condense readily.
Their practical equivalent weight is typically 220-280
on a solids basis, and high concentrations of themelamine resins in the formulation result in highfilm hardness and improved exterior durability.
However, this may also yield lower film flexibility andlower adhesion properties. They too can be stabilized
by adding amines and stabilizing alcohol to theformulation.
n-Butylated High Imino Melamine resins
Butylated high imino melamine resins are similar to
those in the high imino methylated melamine series as
they are partially methylolated and highly alkylated.
They differ from the high imino methylated melamine
resins in that they are n-butylated. The butoxy sites
impart improved flow, leveling and intercoat adhesion
properties. As in the methylated series, their compo­
sition contains primarily alkoxy/imino or alkoxy/NH

iso-Butylated Melamine resins
The iso-butylated melamine resins in this category
are similar to polymeric n-butylated resins and differ
only in that they are “iso” rather than “n”-butylated.
It is generally believed that iso-butylated melamine
resins cure faster than n-butylated resins, althoughdifferences in extent of methylolation, alkylation andpolymerization are believed to be more significant
factors with respect to cure response. The comments
made previously concerning the n-butylated resins
also apply to the iso-butylated resins.

High Solids Urea resins
Methylated resins
Methylated urea resins were designed for waterborneand solvent-based formulations for interior andnon-UV resistant applications. They differ from eachother primarily in their extent of methylolation andmethylation. As with other amino resins for coatings,
higher extents of alkylation result in improved
compatibility with most binders, improved stability,
better flow and leveling - but slower cure response.
These resins require the addition of a strong acidcatalyst for acceptable cure response at 125°C. Forvery low temperature cure systems - for example,
those for wood finishes - a 2-component formulation isnecessary. In such formulations, the acid catalyst is
added to the fully-formulated system just prior to use.
If the bake temperature is around 70°C, a concen­
tration of 1-2% on total binder solids of a strong or
weak acid is recommended. In general, urea resins
react with the hydroxyl, carboxyl and amide functionalsites on polymers, but they also have a high tendency
for self-condensation. Their practical equivalent weightis in the range of 180-260. The use of a blocking amine

for the acid catalyst and the addition of a stabilizing
alcohol to the formulation enhances formulation
stability. The latter approach is recommended for
2-component formulations.
Butylated resins
The one resin in this category, CYMEL® U-80 resin, issimilar in composition to several of the methylated
resins except that its alkylation alcohol is n-butanol.
This resin is also recommended for interior andnon-UV resistant coatings; it is used primarily insolvent-based systems. It is very hydrophobic andstable but slower curing than its methylated
counterparts. A strong acid catalyst is recommended
for acceptable cure response at 125°C. Other
formulation details are the same as those given formethylated resins.

Benzoguanamine and Glycoluril resins
Benzoguanamlne resins
Benzoguanamine resins are similar to melamine-based
resins in that they too are triazine based, but in thisinstance the triazine has a benzene group substitution.
Therefore, they are less functional than melaminebased resins and are not UV resistant.
Benzoguanamine resins are noted for their enhanced
film flexibility/toughness and for their chemical
resistance. They are typically used in primers, container
coatings and appliance finishes. Usually, highly
alkylated, monomeric benzoguanamine resins result inhigher film flexibility than that which can be achieved
with other types of resins, but they also require theaddition of a strong acid catalyst for adequate cure at

Product Name

Non Volatile %temperatures greater than 125°C. Their practicalequivalent weights are slightly higher than the practicalweights of their melamine counterparts and range from
160-220.
The less alkylated polymeric resins only require theacidity of the other components in the formulation to
cure adequately at greater than 125°C, but they havehigher VOCs in a solvent-based formulation. Their
practical equivalent weights are also slightly higher thanthose of their melamine counterparts and range from200-260 on a solids basis. The use of a blocking amine
and the addition of a stabilizing alcohol to theformulation should enhance formulation stability.

Solvent

Glycoluril resins
Glycoluril resins are similar to their melamine resinscounterparts in that they too are based on a ring
structure, glycoluril. Similar to benzoguanamine resins,
they are less functional than melamine resins but are
UV resistant and can be used in exterior coatings.
Their advantages are film toughness and flexibility,
ability to adhere to metals and low formaldehyde
release on curing. There are two categories in the
product line, that of unalkylated methylol glycoluril
resins, and those which are highly alkylated. CYMEL®
1172 is unalkylated and was designed for water-based
coatings with low temperature cure performance

properties. The highly alkylated resin, CYMEL® 1170,
was designed to replace HMMM where there is a desire
to improve film flexibility. The same comments
concerning highly alkylated monomeric melamine
resins also apply to the alkylated glycoluril resins.

Formaldehyde Free resins
CYMEL® NF 2000ACYMEL® NF 2000A crosslinking agent is a uniquetrifunctional melamine-based crosslinker containing
reactive carbamate functionality. It can be used tocrosslink hydroxy- and epoxy containing polymers togive highly durable, acid-resistant films that exhibit afavorable balance of hardness and flexibility. An
important feature of CYMEL® NF 2000A is that it does
not contain or emit formaldehyde on cure. It can be
employed as the sole crosslinker in a coating or ink
formulation, or it may be used at lower levels in
combination with other crosslinkers - such as
conventional amino resins or isocynanates - in orderto obtain a balance of properties. CYMEL® NF 2000A is
recommended for high quality durable finishes such as
automotive topcoats, exterior can varnishes and coilcoatings. CYMEL® NF 2000A reacts with hydroxyfunctional backbone resins at >125°C bake schedules

CYMEL NF 3030
CYMEL® NF 3030 is the waterborne version of CYMEL®
3041. CYMEL® NF 3030 contains no organic solvent
and therefore no solvent is released on cure, allowing
for formulation of ultra-low VOC coating systems.
Pairing with VIACRYL® SC 6834w/42WA nonionic acrylic®

emulsion allows for the formulation of a two-packambient or low bake system for industrial wood
applications with superior catalyzed pot life relative
to isocyanate-based systems. Coatings are typicallysandable in 30-45 minutes following coating application
under ambient conditions. The finished coating
provides a balance of properties including early
hardness development, chemical resistance, cold checkresistance and very good appearance with minimal
grain-raising.
CYMEL® NF 3041
CYMEL® NF 3041 is a partially n-butylated crosslinking
agent designed for two-pack ambient and heat cured
formulations for industrial wood and plastic
applications. These systems have excellent early
hardness, resistance properties, appearance and hot/cold cycle flexibility. CYMEL® NF 3041 is a very effective
crosslinking agent for alkyd, polyester and acrylic

polymers containing primary hydroxyl functionality.
CYMEL® NF 3041 resin requires the addition of an acidcatalyst to the formulation in order to obtain effective
cure for both ambient and heat cured applications. It is
recommended to use 2.0% CYCAT® 500 based onweight of total binder solids. However, the acidity ofother formulation components may affect the reaction
rate and should be evaluated in combination with thecatalyst. Catalyzed potlife can be extended by theaddition of 10 to 20% primary alcohol on total binder
solids. Methanol or ethanol is preferred to ensure early
hardness development and sandability. The coatings
demonstrate very good flow, gloss, early film hardness,
early print resistance and chemical resistance.

to form urethane linkages. Cure can typically be
accomplished without use of a catalyst to yield films
that exhibit excellent hardness, chemical resistance,
exterior durability and environmental etch resistance.
Addition of low levels of acid catalyst (e.g. 0.5% dodecyl
benzene sulfonic acid on binder solids) has been foundto improve humidity resistance properties in somesystems. Both catalyzed and uncatalyzed formulations
show good 1K package stability at 23°C. CYMEL® NF
2000 will react with carboxy functional backbone resins,
but require bake temperatures >150°C.

Catalysts for Industrial CoatingsCYCAT® Catalysts
allnex supplies acid catalysts for accelerating the cureresponse of amino crosslinking agents. Each catalyst isdesigned to fulfill a specific applications requirement,
and in most cases, one catalyst will be preferable overanother depending on formula composition and curingconditions.

Catalyst Selection
deactivation of the sulfonic acid is a very important
tool to achieve the desired balance of storage stabilityof a catalyzed system followed by rapid cure when thecoating reaches the desired temperature.
Acid Types
Strong acids are most effective for highly alkylated
melamine, benzoguanamine and all ureaformaldehyde resins.
Weak acids are most effective for both the crosslinking
and self-condensation reactions of resins which
are subject to general acid catalysis. Thus, high NH
containing resins and partially alkylated melamineformaldehyde resins and all conventional butylated
resins benefit most by the use of weak acids as
catalysts. However, for high temperature bakeOEM auto clear coats, dodecylbenzenesulfonic acid
(DDBSA) catalyst are also very effective. Weak acids
include mono and alkyl phosphates, phosphoric acid,carboxylic acids, and pyrophosphates such as CYCAT®
296-9 catalyst. CYCAT® XK 406N catalyst is especiallydesigned for phenolic resins.

Catalyst Selection Criteria
The reaction of amino resins and polyols iscomplex and often requires acidic catalysts. The
relative efficiency of catalysts correlates to theacidity, and the overall reaction rate is directly
proportional to the concentration of the catalyst.
Frequently used catalysts are p-toluenesulfonicacid (PTSA), dodecylbenzenesulfonic acid (DDBSA),
dinonylnaphthalenesulfonic acid (DNNSA),
dinonylnaphthalenedisulfonic acid (DNNDSA) andorganic phosphoric acid esters.
Ionic or covalently blocked sulfonic acid catalysts
are used in amino resin-based stoving systems. The
