Akron Coating and Adhesives ACA-20-649

Akron Coating and Adhesives ACA-20-649 is a pressure sensitive adhesive composed primarily of synthetic polymers and avoids natural rubber latex. The polymer is crosslinked to enhance chemical and heat resistance. Heat and perspiration do not affect its high tack and shear resistance. A 1 mil dry adhesive film is recommended as a starting point for testing. Rough topography such as fabrics may require greater adhesive thickness.

Applications & Uses

Compatible Substrates & Surfaces
Typical Use

Designed for skin adhesion applications such as the padding used in shoes as well as other skin padding and plasters. It may be used on a wide variety of plastic films and foams. However, PVC containing migratory or monomeric plasticizers will degrade the adhesion properties with time and are not recommended.

Coating Method

Wire wound bar, Knife and Gravure.

Clean Up

Washing with water will clean the wet coating. The dry coating may require a toluene wash. Toluene is a flammable solvent and must be used according to OSHA safety standards.
