Abstract
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.
