The invention relates to a sizing composition for a thermal and/or acoustic insulation product, based on mineral wool, comprising an epoxy resin of the glycidyl ether type, an amine hardener and an accelerator chosen from imidazoles, imidazolines and mixtures thereof. Application to the manufacture of thermal and/or acoustic insulation products having improved mechanical properties after aging, especially in a wet environment.

Sizing composition for an insulating product based on mineral wool, and resulting products

The invention relates to a thermal and/or acoustic insulation product based on mineral fibers for use above 150&#xb0; C., especially between 200 and 500&#xb0; C., or even up to 700&#xb0; C. and higher in the case of rock fibers, which comprises at least 1%, or at least 2% and even more than 4% by weight of binder obtained from a sizing composition, the resin or resin mixture of which consists substantially of at least one epoxy-type resin whose EEW value is between 150 and 2000, preferably at least 160 and/or at most 700, or even at least 170 and/or at most 300.

Insulation product, such as a thermal insulation product, and production method thereof

Insulating product based on mineral wool sized with a binder based on a phenol-formaldehyde resin, in which the binder comprises, as a mixture: Use of such a sizing composition for manufacturing insulating products, while reducing the emissions of ammonia gas on the manufacturing line.

Insulation product in particular thermal containing a binder based on phenol-formaldehyde resin and method for making same

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.
