*These items are provided for general information only. They are approximate values and are not considered 

part of a product specification.

Typical Uses

Laminations that require outstanding adhesion to aluminum foil with high degrees of bond strength, age 

stability, thermal resistance and chemical resistance. Typical laminations for which it is suitable are: 

Aluminum Foil/Polyester Film

Aluminum Foil/Nylon

Aluminum Foil/Treated Polyethylene

Aluminum Foil/Treated Polypropylene

Copper Foil/Polyamide Film

Copper Foil/Polyester Film

Mixing for Use

Adcote 76P1-38 should be mechanically agitated in the drum prior to catalyzing or dilution. Combine

5.0 parts Coreactant F with 100 parts Adcote 76P1-38 just before use. Higher levels of Coreactant F should 

be thoroughly evaluated where high degrees of chemical and thermal resistance are required. Coreactant F 

container must be kept closed when not in use. Thin as desired with MEK, toluol or 99% Ethyl Acetate. 

Adhesive Application

Adcote 76P1-38 can be applied by gravure, smooth roll or reverse roll techniques. The adhesive is generally 

applied to the less porous, more stable substrate. 

Adhesive Weight

Approximately 3.2-4.8 grams of dry adhesive per square meter will generally provide excellent results in 

laminations of light gauge substrates. Higher adhesive weights may be required in laminations of heavy 

gauge substrates and/or where high degrees of thermal or chemical resistance are required. 

Drying

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

range of 200-250F are generally suitable.

Laminating 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, however, 

temperatures approaching 350F may be required to obtain optimum adhesive performance in laminations of 

heavy gauge substrates or where adhesion is of prime importance. 

Bond immediately off the laminator is fair. Maximum thermal and chemical properties will develop within 

7-14 days. For high performance applications, post-curing at elevated temperatures of 120-150F is 

recommended.

High molecular weight polyesters that are used in solution adhesives like Adcote 76P1-38 have a tendency to 

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

to temperature 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 

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.

Safety, Handling and Storage

 Store in cool, dry, well ventilated area.

 Follow good manufacturing and handling practices.

 Wash thoroughly after handling. Wash contaminated goggles, face shield, and gloves. 

Professionally launder contaminated clothing before re-use.

 ATTENTION! Container can be hazardous when empty. Follow label warnings even after container 

is empty. Do not reuse empty container without professional cleaning.

 Refer to Material Safety Data Sheet for more information.
