Abstract

A process for the production of composite materials having a reduced formaldehyde emission, principally those comprising cellulose-containing materials, using a formaldehyde scavenger, wherein material pieces are impregnated with an aqueous or pulverulent, precondensed formaldehyde resin, a moulding is produced from the impregnated pieces, and the moulding is subsequently cured on exposure to heat, characterised in that the curing is carried out in the presence of a formaldehyde scavenger in pulverulent or prilled form, in each case provided with a water-resistant and/or water-impermeable coating.
