Abstract

A sizing composition which is a phenol-formaldehyde resin substantially free of urea or of a urea derivative and which has reduced emissions of isocyanates upon heating. Insulation products based on mineral wool, especially glass wool or rock wool, which are suitable for mass-produced thermal appliances and contain the sizing composition have reduced organic emissions during manufacturing and when used in thermal appliances.
