Epoxy Hardener

Description

What is Epoxy Hardener?

An Epoxy Hardener is a chemical curing agent that reacts with epoxy resin to form a strong, durable, and thermoset polymer. It initiates the cross-linking process, giving the final epoxy system its strength, adhesion, chemical resistance, and mechanical properties. Different hardeners (like amine, anhydride, or polyamide types) are selected based on desired curing speed and performance. Epoxy hardeners play a vital role in the curing process by reacting with epoxy resins (Part A) to form strong, durable, and chemical-resistant thermoset polymers. Mixing and blending epoxy resin with the right hardener (Part B) ensures optimal adhesion, strength, and resistance. At Chemex Chemicals, we offer epoxy hardeners in a variety of grades and appearances — from crystal clear transparent to darker shades — depending on your requirements.

Chemex Chemicals, with over three decades of industry expertise, is a trusted Importer & Supplier of Epoxy Hardeners in India. We deliver premium-quality curing agents that enhance the performance of epoxy resins across a wide range of industrial applications. Our focus has always been to provide superior quality, reliable supply, and customized solutions to meet the needs of our customers in the coatings, electrical, composites, and construction industries.

Types of Epoxy Hardeners

We supply a wide range of epoxy curing agents suitable for diverse industries and applications:

• Phenalkamines – Mannich-type epoxy hardeners derived from CNSL (Cashew Nut Shell Liquid). Known for superior corrosion resistance, fast curing in humid conditions, and excellent performance in marine & protective coatings.

• Polyamides – Formed by the reaction of dimer acids with polyamines, polyamide hardeners provide flexibility, chemical resistance, and effective curing at room temperature.

• Cycloaliphatic Amines – Derived from cyclic aliphatic compounds, these hardeners impart unique strength, hardness, and excellent dielectric properties.

• Polyether Amines – Featuring polyether chains terminated with amine groups, these hardeners offer versatility, toughness, and high resistance under demanding conditions.

• Phenolic Hardeners – Based on phenolic compounds, suitable for use with poly-functional epoxies in coatings and adhesives.

• Polyamidoamines – Produced by reacting polyamines with dimerized fatty acids, offering good adhesion, flexibility, and resistance.

• Anhydride Hardeners – Low-viscosity curing agents with high latency, ideal for electrical applications such as transformers, capacitors, and castings. They provide excellent dielectric and mechanical properties.
