The company
A chemical new-materials partner since 2007
Founded in Suzhou, Henster Industrial is a chemical new-materials enterprise integrating research, production, sales and service — specialised in epoxy amine curing agents for protective coatings, adhesives, high-performance composites, casting and potting, and waterborne epoxy systems.
From our R&D centre at Suzhou Nanopolis to production sites in Suzhou, Fuyang and Shishou, we combine formulation know-how with industrial scale — and build every product around the principle of integrity, pragmatism, cooperation and win-win.

Why Henster
Built for formulation partners, not just buyers
We work upstream with formulators: adapting amine backbones, tuneing pot life and cure speed, and supplying consistently — batch after batch.
Custom formulation
Dedicated workshops in Fuyang build customer-specific grades — viscosity, pot life, colour and performance tuned to your system.
In-house R&D
Our research centre at Suzhou Nanopolis, operational since 2021, focuses exclusively on new chemical materials.
Industrial scale
20,000+ t/year today, with the 90,000 t/year Shishou plant commissioned in early 2024 for long-term supply security.
Documentation & service
TDS, safety documentation and technical support for every grade — with replies within one business day via our contact form.

FAQ
Questions, answered
The essentials for formulators and procurement teams. All questions →
What is an epoxy curing agent and which one should I choose?
A curing agent (hardener) crosslinks liquid epoxy resin into a solid thermoset. The right choice depends on your application, required cure speed, service temperature and chemical exposure — our team will recommend the best grade from your resin system and targets via the contact form.
Can Henster develop a custom curing agent for my formulation?
Yes. Dedicated production workshops in Fuyang, Anhui are configured for customer-specific formulations, from small trial batches to full-scale supply. Send us your requirements and performance targets through the contact form.
What production capacity do you have?
We currently produce more than 20,000 tonnes of curing agents per year across our Suzhou and Fuyang sites. Our new plant in Shishou, Hubei — designed for 90,000 t/year — was officially commissioned in early 2024, securing supply for large projects and long-term contracts.
How do I get a Technical Data Sheet or a sample?
