Frequently Asked Questions

Find answers to common inquiries about our products and services.

What is DETDA used for?

Diethyltoluenediamine (DETDA) is a fast-reacting aromatic diamine used as a curing agent and chain extender in polyurethane systems, particularly in elastomers, coatings, and adhesives.

How does DMTDA differ from DETDA?

DMTDA (Dimethyl Thio-Toluene Diamine) has a sulfur atom in its structure, making it a slower-reacting chain extender compared to DETDA. It's ideal for applications requiring longer pot life and improved mechanical properties.

Are your flame retardants environmentally friendly?

We are actively developing and producing environmentally friendly alternatives. Our R&D team collaborates with academic institutions to innovate sustainable solutions that meet regulatory standards.

Can you provide custom synthesis services?

Yes, we offer custom synthesis and private labeling for specialty chemicals, including pharmaceutical and pesticide intermediates, based on client specifications.

What are your main export markets?

Our products are exported globally, with strong presence in North America, Europe, Southeast Asia, and the Middle East.
