Description

A blend of fine cotton fibers, used as a thickening additive for bonding applications.
Epoxy thickened with 403 fibres provides good wetting out of the substrate and excellent gap-filling properties. They give the resin a better viscoplasticity and absorb tensile forces.
Add 4% to 16% by weight of 403 to WEST SYSTEM epoxy mix.

Colour: off-white.
