ADCOTETM 812/ADCOTE 811B 

Laminating Adhesive

Description

Adcote 812/Adcote 811B is a two component, high performance adhesive system. Adcote 812 can be used 

with different coreactants to reach different performance levels. When Adcote 812 is used with Adcote 811B, 

this combination is designed for high temperature laminate use, including retort applications. All adhesive 

combinations adhere to aluminum foil and a variety of film substrates, providing high initial green bond, and 

offering excellent heat and chemical resistance properties.

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 combust 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.

Adcote 811B is moisture sensitive. Containers should not remain open for an extended period of time.
