Polyamide Hardener Wholesalers In Raipur

A polyamide hardener is a type of curing agent primarily used with epoxy resins to create tough, chemically resistant coatings, adhesives, sealants, and composites. These hardeners are based on polyamide resins, which are polymers formed from dimerized fatty acids and polyamines.

 Key Properties of Polyamide Hardeners

Property Description

Type Amine-based curing agent (specifically polyamide)

Curing Room temperature (ambient) curing, slower than some other systems

Flexibility Good flexibility and toughness

Chemical Resistance Excellent resistance to water, alkali, and some solvents

Adhesion Strong adhesion to a variety of substrates (metal, concrete, wood)

Pot Life Long (due to slow curing), which is useful for extended working time

Color Usually amber or brownish liquid

Viscosity Medium to high, depending on formulation

Typical Applications

Epoxy floor coatings

Marine and protective coatings

Adhesives and sealants

Composites (fiberglass laminates)

Potting and encapsulation of electronics

Concrete bonding agents

Technical Specifications (Typical Ranges)

Property Value

Viscosity @ 25°C 1,000 – 10,000 cP

Amine Value 200 – 450 mg KOH/g

Mixing Ratio (with epoxy resin) Typically 1:1 to 1:2 by weight or volume, depending on formulation

Working Time / Pot Life 30 minutes – several hours

Cure Time Touch dry in 4–8 hours, full cure in 7 days (depending on temperature/humidity)

Shelf Life 1–2 years in sealed container

Advantages

Excellent adhesion and flexibility

Good chemical and water resistance

Longer pot life and working time

Suitable for large surface areas and ambient cure applications

 Disadvantages

Slower curing compared to cycloaliphatic or aliphatic amines

Lower chemical resistance than some advanced curing agents (e.g., polyamine or anhydride types)

Darker color may limit use in clear or light-colored systems
