Microfibres are very fine wood-cellulose
fibres commonly used to create structural
adhesives for bonding both wood and grp.
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,
microfibres 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. Where
the strongest bond is required, e.g. timber scarf joints, microfibres
should always be used in preference to hollow sphere-types of filler.
For bonding parallel to the grain with lower density, lower strength
timbers, such as cedar or obeche, a microballoon mix is often adequate,
and is of lower density.
