摘要

This invention is concerned with the provision of an improved method of bonding glass wool products by means of a binder composition. In this invention bonding is effected by means of a binder thus formed by diluting a co-polymer resin solution. The co-polymer resin solution is produced by reacting urea with formaldehyde in an aqueous alkaline media in the presence of an amine. The reaction mixture obtained being acidified after which furfuryl alcohol is added. The co-polymer resin is then formed from the furfuryl alcohol and the reaction produced is neutralized to give the desired co-polymer resin solution.
