Adcote L 76-185 adhesive adheres to a wide variety of substrates including cellophane, treated polyolefins, 

polyester, polyamide, aluminum foil, paper, metallized and PVDC coated materials, and the treated 

heat-sealable layers of coextrusions.

Adcote L 76-185 adhesive provides optical clarity, high bond strength, and a high level of heat and chemical 

resistance.

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 not 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.

Alcohol and similar materials containing active hydrogen can react with Adcote L 76-185/Coreactant F

adhesive causing inadequate cure.

Adcote L 76-185/Coreactant F can react or interact with other components of laminations. Retained 

solvents, slip additives, antiblock agents, and contaminated solvents are some of the components that may 

cause property changes of the film and/or adhesive.
