ADCOTETM L 76-185/CR 386

Laminating Adhesive

Description and Features

Adcote L 76-185/CR 386 adhesive is the polyester component of a two component laminating adhesive that

requires the use of an isocyanate coreactant. This polyester, in conjunction with various isocyanate 

terminated coreactants, functions as an adhesive for flexible packaging and industrial laminations. 

Adcote L 76-185/CR 386 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/CR 386 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/CR 386 adhesive 

causing inadequate cure.

Adcote L 76-185/CR 386 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.

Suggested Mixing Instructions

Weigh out the amounts of Adcote L76-185, urethane grade solvent and coreactant that will be used for 

the press ready mix. To the Adcote L76-185 adhesive, add while mixing, the appropriate amount of 

urethane grade solvent to dilute the Adcote L76-185. Then, add the Coreactant CR 386 with mixing. Mix 

for 5 to 10 minutes, and then check the viscosity (at 77°F). Adjust solids or viscosity as needed.
