ADCOTETM 76R44 Laminating Adhesive

Description

Adcote 76R44 is the modified polyester component of a two component, curing type laminating adhesive

designed for use in laminations requiring high degrees of optical clarity. Coreactant 9H1H or Coreactant

9L10 must be used to achieve full properties and full light resistance. It is recommended for bonding 

polyester film to vacuum metallized polyester film for solar control film applications.

Mixing for Use

Adcote 76R44 should be mechanically agitated in the drum prior to catalyzing or diluting. Combine 

100 parts of Adcote 76R44 with the Coreactant of choice just prior to use. Dilute as desired with the desired 

urethane grade solvents and mix thoroughly. 

High molecular weight polyesters that are used in solution adhesives like Adcote 76R44 have tendency to

form a reversible structure in solution with time. This structuring is accelerated when the adhesive is

exposed to temperatures below 50°F. The structuring is reversible if heat and shear is applied to the 

adhesive. We recommend placing the container of adhesive in a steam cabinet, allowing venting of the 

container and heating to 110-140°F. After the adhesive reaches the proper temperature, mix the adhesive 

in the container for 1-3 hours under moderate shear. Use of a disperser or “Cowles” type blade will 

shorten the time needed.

Caution must be taken because of the flammability of the solvents used in the adhesive. Please review

the material safety data sheet for hazards associated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a homogeneous 

mix. Before using the adhesive, check to make sure that all resin has returned to a true solution and no

gels remain.

Adhesive Weight

Approximately 2.0 - 3.5 grams of dry adhesive per square meter (1.25-2.0 lb/ream) will generally provide

excellent results in laminations of light gauge substrates.

21CFR177.1390 L 08/16/2005 ▪ SOLVENT MUST BE COMPLETELY EVAPORATED DURING

DRYING AND CURING. 

▪ PROVIDED THAT IT IS NO MORE THAN 14% OF THE WEIGHT

OF THE CURED ADHESIVE. 

▪ Compositional compliance with 21 CFR 177.1390 requires the use 

of another component that is listed in the same paragraph of 21 

CFR 177.1390. In other words, a component listed in (c)(2)(v) may

NOT be used with a component listed in (c)(2)(vi), unless migration 

studies have affirmed the combination to be in compliance with the 

FDA regulations. This requirement for use of components in the 

same section of 21 CFR 177.1390 applies to the use of this material 

in compliance with 21 CFR 177.1395 as well.

100:8, at 2.9 lb/ream, and cured for 8 days at 120F and 3 days at 

room temperature, may be used as an adhesive layer in 

multilaminate food packaging materials with aqueous food types 

with a food contact layer of at least 3 mil cast polypropylene under 

all conditions of use in full compliance with the Federal Food, Drug 

and Cosmetic Act. 

▪ The combination of Adcote 842 and COREACTANT (TM) 9L10, 

when used in a ratio of 100:8.0 and cured for seven days at 115F
