ADCOTETM 76T198 Laminating Adhesive

Description

Adcote 76T198 polyester 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 76T198 adhesive adheres to polyester, nylon, aluminum foil, and the treated side of polyethylene and

polypropylene.

Adcote 76T198 adhesive provides optical clarity, high bond strength, and excellent heat and chemical

resistance.

PACKAGING AND

CONVERTING

ADHESIVES AND SEALANTS 
High molecular weight polyesters that are used in solution adhesives like Adcote 76T198 have a tendency to

form a reversible structure in solution with time. This structuring is accelerated when the adhesive is exposed

to temperature below 50°F. The structuring is reversible if heat and shear is applied to the adhesive. We

recommend placing the container of adhesive in a steam cabinet, allowing venting of the container and

heating to 110-140°F. After the adhesive reaches the proper temperature, mix the adhesive in the container

1-3 hours under moderate shear. Use of a disperser or “Cowles” type blade will shorten the time needed. 

Caution must be taken because of the flammability of the solvents used in the adhesive. Please

review MSDS for hazards associated with the adhesive. 

Attempting to re-disperse without heat may reduce the apparent viscosity, but not result in a

homogeneous mix. Before using the adhesive, check to make sure that all resin has returned to a true 

solution and no gels remain. 

Safety, Handling and Storage 

• Store in cool, dry, well ventilated area. 

• Follow good manufacturing and handling practices. 

• 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 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 this system and cause inadequate

cure. 

This system 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.
