What This Category Covers
Epoxy hardeners start and control the crosslinking of an epoxy resin, and in doing so they set strength, adhesion and chemical resistance. Two very different families sit here: latent imidazoles for heat triggered one component systems, and polyetheramines for tough flexible ambient cure work.
One component epoxy systems need a hardener that stays inert at room temperature and fires cleanly at the activation temperature. Flooring and composite systems need the opposite: long pot life and no surface blush. Both problems are solved on this page.

All Epoxy Hardener Products
Every product in this category, with its full grade table on the product page.
Core Advantages
Latent Cure Where You Need It
Imidazole grades are listed with melting point and activation temperature so one component storage stability can be predicted.
Toughness Without Blushing
Polyetheramine grades are quoted with amine hydrogen equivalent weight, viscosity and recommended ratio, and are supplied for solvent free and low VOC systems.
Physical Forms From Liquid to Micronised Powder
Flake, powder, micronised powder and liquid grades, so the hardener suits the mixing equipment you already own.
Industries That Use These Materials
Protective coatings are bought on service life. The raw material decisions behind them are about crosslink density, film flexibility and how the system behaves once VOC limits tighten.
See Applications
Electronic materials fail on impurities long before they fail on mechanical properties. Total chlorine, colour and latency matter more here than headline strength figures.
See Applications
Adhesive makers live between two constraints: open time long enough to apply the product, and final strength high enough to replace a mechanical fastener.

EEW, colour, viscosity and softening point are the four numbers that decide whether a resin grade fits your process.
Read The Guide
Latency is the whole point. This guide explains what melting point and activation temperature tell you about shelf life and cure schedule.
Read The Guide
Amine hydrogen equivalent weight and molecular weight explain almost everything about how a polyetheramine will behave in your system.

How many epoxy hardener grades do you list?
This category covers 2 product families, and each one carries the full manufacturer grade table on its own page rather than a summary.
Can I order a mixed container across categories?
Yes. Isocyanates, curing agents, resins, polyols and chain extenders can go on one order, which is the main reason buyers consolidate with us.
Do you supply samples from this category?
Samples for laboratory testing and formulation validation are free of charge with you covering shipping, and take about 7 days.
What are the payment terms?
30% deposit in advance, 70% against a copy of the bill of lading. Bank transfer, Xtransfer or PayPal.
How is hazard packing handled?
High quality export packaging as standard, with specialised hazard packing for dangerous goods and validated cold storage shippers for temperature sensitive items. Non standard packing may carry an additional charge.
