ADCOTETM 76R36B-33 

Laminating Adhesive

Description

Adcote 76R36B-33 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 must be

used to achieve full properties. It is recommended for bonding polyester film to vacuum metallized polyester

film for solar control film applications.

Mixing for Use

Adcote 76R36B-33 should be mechanically agitated in the drum prior to catalyzing or diluting. Combine 

Adcote 76R36B-33 with Coreactant 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 76R36B-33 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 MSDS 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.

Drying

Use sufficient temperature and air velocity to assure complete solvent removal. Oven temperatures in the

range of 200-250°F are generally suitable.

PACKAGING AND

CONVERTING

ADHESIVES AND SEALANTS 
Laminating and Combining

Laminate to the second substrate using heated pressure nip rollers at a temperature high enough to assure 

complete wetting of the secondary substrate. A minimum temperature of 160°F is recommended. 

Maximum thermal and chemical properties will develop within 7-14 days. 

Precautions

See Material Safety data Sheet for hazardous ingredients, flammability, disposal, and related handling 

information.
