Functional additives

Introduction

STDResin 8510 is composed of epoxy resin (Component A), modified curing agent (Component B), and catalyst (Component C), specifically designed for pultrusion processes. It features low viscosity, long pot life, excellent processability, rapid curing at appropriate temperatures, outstanding mechanical properties, strong fiber adhesion, and recyclability through degradation.

 

Applications

• Pultruded pipes, rods, and profiles of various cross-sectional shapes and sizes
• Composite products manufactured by other pultrusion processes
