ADCOTETM L 76X161 

Laminating Adhesive

Description 

Adcote L 76X161 is an isocyanate-terminated polyester urethane component of a two component, 

high-application solids adhesive system, supplied in a non-VOC solvent. The use of CR 86X101 is

required to achieve full cure properties. This adhesive system adheres to a variety of substrates with

excellent heat and or chemical resistance. 

Adcote L 76X161/CR 86X101 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 L 76X161/CR 86X101 is suggested for optimum performance where slip modified films are used 

and applications requiring excellent heat and chemical resistance. Adcote L 76X161/CR 86X101 also

offers the benefit of a low nip temperature requirement, especially useful when producing temperature 

sensitive constructions.

PACKAGING AND

BUILDING MATERIALS 
Suggested Mixing Procedure 

1. Pre-weigh Adcote L 76X161 into a clean, mixing container that is properly grounded. 

2. Add the appropriate amount of urethane grade solvent or high purity methyl acetate. 

3. With gentle mixing, add the recommended amount of CR 86X101. 

Note: The Adcote L 76X161, CR 86X101 and the mixing procedure involve 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 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.
