ADCOTETM 577A/577C 

Laminating Adhesive 

Description 

Adcote 577A is the isocyanate-terminated polyester urethane component of a two-component adhesive 

system that requires the use of Coreactant Adcote 577C to achieve full properties. 

Adcote 577A/577C adhesive provides high bond strength and a high level of heat and chemical resistance. 

Adcote 577A/577C exhibits high initial shear strength that helps mitigate laminate defects. 

The cure rate of laminations made with Adcote 577A/577C adhesive is dependent on the temperature and 

relative humidity of the storage or holding area.

Typical Uses 

Adcote 577A/577C 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 577A/577C can be used in retortable 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 component. 

Mixing Instructions 

Add the proper amount of Adcote 577C coreactant to the to the Adcote 577A adhesive. Mix thoroughly until 

well dispersed.

PACKAGING AND 

CONVERTING 
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 (except for the small amount contained in Adcote 577C) and similar materials containing active 

hydrogen can react with Adcote 577A adhesive causing inadequate cure. 

Adcote 577A 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.
