ADCOTETM 545E Laminating Adhesive

Description and Features

Adcote 545E is an ethyl acetate solvent analog of Adcote 545.

Adcote 545E 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 545E adhesive adheres to a wide variety of substrates including cellophane, treated polyolefins,

polyester, polyamide, aluminum foil, metallized and PVDC coated materials, and the treated heat sealable 

layers of coextrusions. 

Adcote 545 adhesive provides optical clarity, high bond strength, and a high level of heat and chemical

resistance.

PACKAGING AND

BUILDING MATERIALS 
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 545E adhesive

causing inadequate cure. 

Adcote 545E 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.
