At Feiyang Protech Corp., Ltd., we specialize in the development and production of custom-made epoxy curing agents.
Our expertise covers the full spectrum of curing agent types, including aliphatic amines, modified amines, polyamides, phenolic amines, aromatic amines, and accelerators.
We understand that many customers require equivalents to well-known international brands such as Huntsman, BASF, Evonik, and Cardolite.
With our strong R&D capability and flexible production lines, we are able to design and manufacture tailored curing agents upon request, ensuring performance comparable to international reference grades while offering significant cost advantages.

The above grades represent only a portion of our full range. Custom formulations and additional equivalents are available upon request.
Our state-of-the-art facility, completed on April 16, 2024, is dedicated to the R&D, application, and promotion of cutting-edge polyaspartic polyurea materials. It is supported by a team of over 50 experts and industry leaders.
Our vision is to become a global leader in polyaspartic polyurea material R&D, mastering the core technologies across the entire industry chain. Through digitalization, informatization, and intelligentization, we aim to provide high-quality new material solutions for customers worldwide.
In July 2023, Feiyang commenced the design and construction of a new 26,000-ton polyurea materials project. Once operational, this will increase Feiyang’s total resin production capacity to 46,000 tons.
The new project has significantly enhanced the original polyaspartic resin production process, resulting in a fully automated production line covering everything from raw material storage to manufacturing and packaging.
This has reduced the required workforce by 50% and doubled the economic output per employee. Moreover, the production line has been upgraded to directly produce high-purity, bio-based polyaspartic polyurea resin.
