Pultrusion Resin
Pultrusion Resin — 71/77/78 Series
High-reactivity, low-shrinkage unsaturated polyester resins optimized for the pultrusion process. From fast-line-speed grating production to high-temperature epoxy-modified profiles, these grades deliver excellent glass wet-out, consistent curing, and superior mechanical properties.
Product Overview
Our Pultrusion Resin series provides five specialized grades for continuous fiber-reinforced profile manufacturing. The high-reactivity AT-PUL-02 delivers maximum line speed for standard profiles, while the thixotropic AT-PUL-03 handles complex angled and irregular cross-sections without sagging. The AT-PUL-04 combines medium viscosity with excellent water and weather resistance, ideal for outdoor installations. For surface-critical applications, AT-MAR-03 offers low shrinkage and low wave for premium surface quality. The epoxy-modified AT-PUL-01 provides the ultimate heat resistance with HDT ≥120°C for demanding environments.
