ADCOTETM L 76-186/CR-385

Laminating Adhesive

Description

Adcote L 76-186 is the isocyanate-terminated polyester urethane component of a two-component adhesive 

system that requires the use of Coreactant CR-385 to achieve full properties.

Adcote L 76-186/CR-385 adhesive provides high bond strength and a high level of heat and chemical 

resistance.

The cure rate of laminations made with Adcote L 76-186/CR-385 adhesive is dependent on the temperature 

and relative humidity of the storage or holding area.

Typical Uses

Adcote L 76-186/CR-385 can be used in all typical laminations for laminating aluminum foil and a variety of 

polyester, polyolefin and coextruded films typically used in food, medical and industrial packaging 

applications. Adcote L 76-186/CR-385 can be used in “hot fill” structures to laminate polyester to foil or nylon 

to foil. The adhesive layer must be separated from the food product by a functional barrier. Consult your 

Rohm and Haas technical sales representative for suggestions regarding the inner ply, i.e., the foil/cast 

polypropylene lamination. 

Mixing Instructions

Add the proper amount of CR-385 coreactant to the Adcote L 76-186 adhesive while mixing. Mix thoroughly

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 76-186 adhesive causing 

inadequate cure.

Adcote L 76-186 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.
