ADCOTETM 49-221

Laminating Adhesive

Description and Features

Adcote 49-221 adhesive 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 49-221 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 49-221 adhesive provides optical clarity, high bond strength, and a high level of heat and chemical 

resistance.

Typical Uses

The principal uses for Adcote 49-221 adhesive with coreactant are in meat and cheese packaging, coffee 

pouches, condiment packaging, cable wraps, and liquid packaging. The use of Coreactant CT provides 

shorter cure times, and better 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.

Safety, Handling and Storage

 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.

Alcohols and similar materials containing active hydrogen can react with Adcote 49-221 adhesive causing 

inadequate cure.

Adcote 49-221 can react or interact with other components of laminations. Retained solvents, slip additives, 

anti-block agents, and contaminated solvents are some of the components that may cause property 

changes of the film and/or adhesive.
