Viscosity versus injection temperature

Viscosity build-up versus temperature

Araldite® FST 40004 / 40005 is a radically novel thermoset, aiming

at providing innovative solutions for designing railway parts.

Araldite® FST 40004 / 40005 is designed for direct liquid processes with unique combination of mechanical performance and fi re resistance properties.

Araldite® FST 40004 / 40005 takes RTM, infusion and pultrusion into a new dimension enabling effi cient production of structural carbon and glass composites parts with maximized weight savings.

Applications in railway

Structural FST composite parts:

> Highly complex

> Integrating function

> Small / medium with fast and high temperature process

> Large with low temperature injection

> High thickness thanks to very low exotherm

Key features

> Meets EN 45545-2 category HL1 / HL2 on R1 / R7 applications

> Halogen free

> Unfi lled

> High modulus

> Compatible to high quality, user-friendly processes:RTM, infusion and pultrusion (injection box)

> Fast RTM curing capability (ca. 5min / 150°C)

> Pultrusion speed of ca. 10 meters / hour
