Abstract

A homogeneous mixture of (A) a furfuryl alcohol/formaldehyde resin (viscosity 15000 to 200000), the resin having been produced by acid resification of furfuryl alcohol and formaldehyde in a molar ratio 0.25 to 1.0 mole formaldehyde per mole furfuryl alcohol, neutralisation of the catalyst used, and removal of the water of condensation, with (B) 5 to 25% by weight of reaction mass of furfural, the binder composition having a viscosity 200 to 5000 cP at 25 deg.C. In production of glass-fibre reinforced articles, using a binder composition as above defined, an acid catalyst e.g. p-toluene sulphonic acid.
