West Sytem 403 Microfibres are a blend of fine fibres used for epoxy thickening additive for thickening epoxy for multi-purpose bonding and gap filling.
Because any low viscosity resin system is readily absorbed into a porous surface such as wood, an unfilled adhesive may tend to give a 'dry joint'. With their absorbent properties. A microfibre blend can retain a significant quantity of adhesive within a joint and limit resin absorption into the surrounding surface, thus ensuring an adequate resin supply for adhesion.
West System 403 provides good wetting out of the substrate and has excellent gap filling properties.
The West System epoxy filler agent comes with a dispensing spoon to improve measurement accuracy.
