ADCOTETM 527 

Laminating Adhesive

Description and Features

Adcote 527 adhesive is an isocyanate terminated polyester urethane adhesive. Adcote 527 adhesive is

used as a single component, which requires moisture to cure and is used with various hydroxyl terminated

coreactants. This polyester urethane alone, or in conjunction with various coreactants, functions as an

adhesive for medical packaging, food packaging, and industrial laminations.

Adcote 527 adhesive adheres to a wide variety of substrates including polyvinyl chloride (PVC), treated

polyolefins, polyester, polyamide, aluminum foil, metallized substrates, copper, steel and paper.

Adcote 527 adhesive provides optical clarity, high bond strength, and a high level of heat and chemical

resistance.

The cure rate of laminations made with Adcote 527 adhesive is dependent on the temperature and relative

humidity of the storage or holding area. 

Typical Properties*

CONVERTING

ADHESIVES AND SEALANTS 
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 527 adhesive causing 

inadequate cure. 

Adcote 527 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. Under certain conditions, Adcote 527 adhesive can contribute to the problem of 

loss of sealability in finished laminations.
