Product Description

Description

Photocurable polyester acrylate 5600F / 5650F: an efficient and environmentally friendly "industrial star". In the modern industry that pursues efficiency and environmental protection, polyester acrylate oligomer has become an innovative representative of photocurable materials with its unique properties. It not only achieves the requirements of high-speed production, but also supports ideal solutions for multi-field applications with its safe, stable, and tough characteristics.

Fast Reaction
Instantly completes cross-linking and curing under UV light in seconds or milliseconds, sharply shortening production cycles.
High Hardness
Hardness is comparable to engineering plastics. Provides superior wear and scratch resistance to maintain smooth surfaces.
