# ADCOTETM 503E

Laminating Adhesive

Description Adcote 503E 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 503E 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.

Adcote 503E adhesive provides optical clarity, high bond strength, and a high level of heat and chemical

resistance.

High molecular weight polyesters that are used in solution adhesives like Adcote 503E 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 ad hesive in a steam cabinet, allowing venting of the container and heating to 110-140°F. After the adh esive 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 re-disperse without heat may reduce t he 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 em pty. Follow label warnings even after container is empty. Do not reuse empty c ontainer without pr ofessional cleaning.

 Refer to Material Safety Data Sheet for more information.

Alcohol and similar materials containing active hy drogen can react with Adcote 503E adhesive causing inadequate cure.

Adcote 503E can react or interact with other component s 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.
