ADCOTETM 548E 

Laminating Adhesive

Description and Features

Adcote 548E 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 548E adhesive adheres to a wide variety of substrates including cellophane, treated polyolefins, 

polyester, polyamide, aluminum foil, paper, metallized and PVDC coated substrates, and the treated heat 

sealable layers of coextrusions.

Adcote 548E 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.

Alcohols and similar materials containing active hydrogen can react with Adcote 548E adhesive causing 

inadequate cure.

Adcote 548E and coreactant 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.
