ADCOTETM 550

Laminating Adhesive

Description 

Adcote 550 is the polyester component of a two component laminating adhesive which 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 550 adhesive adheres to a wide variety of substrates including treated polyolefins, polyester, and,

aluminum foil. 

Adcote 550 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, faceshield, 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.

PACKAGING AND

CONVERTING

ADHESIVES AND SEALANTS 
Alcohol and similar materials containing active hydrogen can react with Adcote 550 adhesive

causing inadequate cure. 

Adcote 550 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.
