Beschreibung
Zusammenfassung:	Composición de encolado para fibras minerales que contiene una resina fenólica líquida constituida de condensados de fenol-formaldehído y de fenol-formaldehído-monoetanolamina, presentando dicha resina fenólica una tasa de formaldehído libre inferior o igual a 0,1% en peso total de líquido, una tasa de fenol libre inferior o igual a 0,5% en peso total de líquido, y una capacidad de dilución en agua, a 20ºC, superior o igual a 1000%, y de de 0,1 a 40 partes en peso para 100 partes en peso seco de resina líquida de un extensor seleccionado entre los hidratos de carbono. The present invention relates to a sizing composition for mineral fibers, especially glass fibers or rock fibers, containing a liquid phenolic resin having a free formaldehyde content, expressed with respect to the total weight of liquid, of 0.1% or less and an extender. Preferably, the liquid phenolic resin is mainly composed of phenol-formaldehyde and phenol-formaldehyde-amine condensates and has a water dilutability, at 20° C., at least equal to 1000%. Another subject of the present invention is the insulating products based on mineral fibers treated by said sizing composition.
