Applications:
Fibre pastes and moulding compounds, synthetic plasters, putties, adhesives, corrosion protection coats, and asbestos substitutes. In the case of coupling, layers to fill and back up edges and embed alignment dowels and screw unions in-mould construction, a mixture of 50 % vol. chopped glass fibre and 50 % vol. cotton flock is mostly used. The volume details are intended to assist in judging the amount supplied. These details refer to the loose bulk amount. The contents may become compressed during transport or storage.
