*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 good 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/Polyester Film

Mixing for Use

Adcote 76P112 should be mechanically agitated in the drum prior to catalyzing or dilution. Combine 6.0 parts

9H1H with 100 parts Adcote 76P112 just before use. Coreactant 9H1H container must be kept closed when

not in use. Thin as desired with MEK, toluene, or 99% ethyl acetate. 

High molecular weight polyesters that are used in solution adhesives like Adcote 76P112 have a 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 Application

Adcote 76P112 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 (1.5 - 2.5 lb/ream) 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 93-121°C (200-250°F) are generally suitable. 

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 70°C (160°F) is recommended. 

However, temperatures approaching the 176°C (350°F) may be required to obtain optimum adhesive 

performance in laminations of heavy gauge substrates or where adhesion is of prime importance. Maximum 

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

Safety, Handling and Storage 

• Store in cool, dry, well ventilated area away from heat and ignition sources. Keep container tightly 

closed. 

• Hot organic chemical vapors can suddenly and without warning, ignite when mixed with air. Ignition 

can occur at typical elevated temperature process conditions. Please evaluate such processes to 

assure safe handling conditions. 

• Support and ground containers before opening, dispensing, mixing, pouring or emptying. Open with 

non-sparking tools. If container is warm, open bung slowly to release the internal pressure. 

• 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 no use heat, sparks, open flames, torches or cigarettes on or near empty containers. 

Do not reuse empty container without professional cleaning. 

• Refer to Material Safety Data Sheet for more information.
