Recyclable polyurethane system STD8100
Introduction
STDResin8100 consists of epoxy resin (Component A) and amine-based curing agent (Component B), specifically designed for vacuum-assisted infusion processes. The combination provides an optimal balance between pot life and reactivity. This system is ideal for large mold production requiring extended infusion time, delivering excellent mechanical/thermal properties in cured state and recyclability through degradation.
Applications
- Wind turbine blades
- Nacelle fairings
- Hub covers
- Composite manufacturing
