What Are Reactive Polyamide Resins?

About Polyamide Resins

Polyamide resins are high-molecular-weight polymers that contain amide linkages in their molecular composition. Nylon and Aramid resins are the subcategories of Synthetic polyamides, which are popular for commercial applications.

These resins are distributed as reactive or nonreactive. The reactive category is utilized primarily as curing agents for epoxy resins which are used in adhesives and surface coatings. The non-reactive polyamides are used majorly n printing inks and hot-melt adhesives.

What Are Reactive Polyamide Resins?

Reactive Polyamide resin is also known as the epoxy hardener, is used primarily as an epoxy curing agent.

The curing agent is responsible for reacting with the epoxy groups contained in the epoxy resins results in hard thermoset materials. These thermosetting materials are used in
coating, adhesives, and composites.

Reactive Polyamides are based on a backbone of aliphatic chains connected via an amide linkage. The polyamide backbone imparts toughness to the final product.

Polyamide curing agents offer good impact strength, crack resistance, good substrate adhesion, and provide excellent water resistance.

Our Speciality Range of Reactive Polyamides

Crest specialty resins offer two grades of reactive polyamides. CPOL 115 and CPOL 125.
CPOL 115 is a general-purpose amino polyamide resin.

It is used along with epoxy resins to produce primer and topcoat as well as thermosetting adhesives for a wide variety of substrates.

The main characteristics of CPOL 115 are excellent resistance, good exterior durability, and
adhesion to metallic substrates.

CPOL 125 is a medium viscosity liquid amino polyamide resin used along with epoxy resins to
produce high-performance coatings structural and laminating adhesives.
