Applicable Base Polymer Properties

Polyamide resins are used in a wide range of solvent-based inks, coatings and adhesive applications where they can provide excellent weatherability and resistance to water, alcohol, dilute acids and alkalis, chemical fumes and corrosive and oxidizing environments. Macromelt® 6238 is a high performance, solid thermoplastic adhesive based on polyamide. The Macromelt product has good adhesion to a variety of substrates including glass, metals, wood, and many plastics.

Resulting Properties

Priming a surface can significantly improve initial and ultimate adhesion to many materials such as plastics and paints because of their low surface energy or the additives they may contain. A primer creates a new surface for the tape to adhere to and can also create a layer that may impede the migration of additives that may be present in a material.

The primers include but are not limited to, polyamide solutions and emulsions, natural and synthetic rubber-based solutions and emulsions, ethylene-propylene copolymer, and vinyl copolymers. In the above formulation, a polyamide solution is used as the primer.
