ADCOTETM 555/ADCOTE 536B

Laminating Adhesive

Description 

Adcote 555 is an isocyanate terminated polyester urethane component of a two component, highapplication solids adhesive system. The use of Adcote 536B is required to achieve full cure properties.

This adhesive system adheres to a variety of substrates with excellent heat and chemical resistance. 

Adcote 555/Adcote 536B is designed for laminating aluminum foil and a variety of polyester, polyolefin and

coextruded films typically used in food, medical and industrial packaging applications. Adcote 555/Adcote

536B is suggested for optimum performance where slip modified films are used and applications requiring

excellent heat and chemical resistance. Adcote 555/Adcote 536B also offers the benefit of a low nip

temperature requirement, especially useful when producing temperature sensitive constructions.

ADHESIVES AND SEALANTS 
Suggested Mixing Procedure 

1. Pre-weigh Adcote 555 into a clean, mixing container that is properly grounded. 

2. Add the appropriate amount of urethane grade solvent. 

3. With gentle mixing, add the recommended amount of Adcote 536B. 

Note: The Adcote 555, Adcote 536B, and the mixing procedure involves handling of flammable solvents. 

1. Ensure there is adequate ventilation when handling and mixing. 

2. Ensure that the necessary grounding or bonding attachments are used on all containers and mixing 

vessels to avoid any static charge buildup while opening containers, pouring the mixture components 

and during mixing.

Cleaning 

1. Immediately clean up spills and splashes in an approved manner.

2. Wash and clean adhesive wetted parts with acetate or ketone solvents at the end of the production

run before the adhesive’s cure progresses too far, ensuring complete removal of the adhesive 

residue. Cured adhesive will be much more difficult to solvent clean from metal parts and from the 

application cylinder. 

3. Cured adhesive may have to be cleaned by long term soaking in solvents, using chemical cleaners or

sending the parts to be professionally cleaned. 

Safety, Handling and Storage 

• Store in cool, dry, well-ventilated area away from heat and ignition sources. Keep containers 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.
