Abstract

1422653 Coated products V D VALGIN V A NOVAK and J S MURASHOV 4 Jan 1973 [4 Jan 1972] 643/73 Heading B2E [Also in Division C3] Flat or shaped surfaces, e.g. of plywood, are sprayed with a foamed plastic comprising an acidic mixture of a liquid phenol-aldehyde resol condensate and 0.15-5.0 parts by wt. per 1 part by wt. of the resol (calculated for the dry products) of a liquid phenol-aldehyde novolak condensate, and/or 0.2-3 parts (per I part by wt. of the resol) of a sulphonated novolak having an average of 0.3-0.9 sulpho groups/phenyl nucleus, and a foaming agent which is a volatile liquid, a compressed gas e.g. air, being optionally used for the spraying which also acts as a foaming agent. The foam acts as an insulation.
