DISPARLON _A670-20M(Anti-sagging/Anti-settling agent)

DISPARLON A670-20M is a thixotropic agent developed as one of A-Series, anti-sagging agents for high-build
coatings, and characterized by its higher flash point and lower content of aromatic solvents.
A670-20M is a paste of amide wax swollen/dispersed in a mixture of solvents composed mainly of mineral spirits. It
is fully activated and, therefore, can easily be used in virtually all the paint production process when used in solvent
based systems.
ADVANTAGES● Strong thixotropy, effective for anti-sagging of high-build coatings.
● Flash point as high as 40°C or more, does not lower Flash point of the paint.
● Aromatics content 20% less.
● Fully activated, can be incorporated by high speed dissolver or Sand mill.
● No seeding and long maintained effects.

APPLICATIONS
A670-20M can be used in almost all solvent based systems and recommended particularly in Alkyds, Acrylics,Epoxies, where higher flash point or lower content of aromatics is required.
Other applications are architectural and heavy duty anti-corrosion paints such as Vinyl, Chlorinated rubbers,
Acrylic/urethanes, Polyester/urethanes, etc.. Especially recommended for use in wood coatings with oil-modified
urethanes.
INCORPORATION
Additive levels : Preferable dosage level per total formulation is 1.0 ~ 5.0 wt.% for anti-sagging and 0.5 ~ 2.0wt.% for anti-settling. However, dosage level may fall out of these ranges depending on yourformulation. The optimal level should be determined by your laboratory tests.
Method: High speed dissolver is recommended.
Dispersingtemperature: Amide component may form particles if it is dissolved into a formulation and later
precipitated during dispersing process. Standard dispersing temperature is between
the room temperature and 50°C to prevent particle generation. Please be careful of thedispersing temperature because particles may occur at the upper side of the standard
temperature range mentioned above if a formulation contains large amount of polar
solvent.

TYPICAL PROPERTIES
Appearance: Light yellow paste

Non-volatile matter: 20% by weight

Solvent: Mineral spirits / Benzyl alcohol

Particles may occur in the paste during storage at a low temperature less than 20°C because of the crystallizationof its ingredients. In such case, please warm the vessel in a heating chamber at the temperature between 35°Cand 40°C for 24 to 48 hours just before using it.
CAUTION
Amide thixotropes may cause low surface tension. Please make sure to check recoatability especially in alkyd
melamine or oil modified alkyd bake systems.
