ADCOTETM 102A 

Laminating Adhesive 

Description 

Adcote 102A adhesive is the polyester component of a two component laminating adhesive which requires 

the use of an isocyanate coreactant. This polyester adhesive, in conjunction with various isocyanate 

terminated coreactants, functions as an adhesive for flexible packaging and industrial laminations.

Adcote 102A 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 co-extrusions.

considered part of a product specification.

** Other coreactants are available for special uses. Consult your Rohm and Haas Sales Representative for 

further information.

The principal uses for Adcote 102A with coreactant are in meat and cheese packaging, coffee pouches, 

condiment packaging, liquid packaging, and high demand film to film and film to aluminum foil laminations. 

Adcote 102A adhesive provides optical clarity, high bond strength, and a high level of heat and chemical 

resistance.

BUILDING MATERIALS

High molecular weight polyesters that are used in solution adhesives like Adcote 102A have tendency to 

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

exposed to temperatures 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 for 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 redisperse 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.

Cleaning

Clean the adhesive from the gravure roll, pan, reservoir and other wetted machine parts as soon as possible 

with MEK, ethyl acetate or other active solvents. Clean up spills immediately. If the cells of the gravure roll 

start to fill in or plug, scrubbing with solvent and a brass brush can usually cleanse the cylinder. Do not allow 

the adhesive to cure on the machine parts, since the adhesive becomes solvent resistant. Cured adhesive in 

the cells of the cylinder will be difficult to remove and may need chemical or ablative cleaning. 

Safety, Handling and Storage

 Store in cool, dry, well ventilated area.

 Follow good manufacturing and handling practices.

 Contains flammable solvents. Always use grounding straps when mixing, transferring and handling to 

avoid static discharge potential.

 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.
