ABSTRACT:
An improvement is provided in the compression molding of lignocellulosic composite articles, such as particle or flake board, in which polyisocyanate binder systems are employed, the improvement being the provision of a novel functional polysiloxane-hydroxyle substituted mono-carboxylic acid or metal salt-isocyanate terpolymer as a release agent on the mold surface or surfaces to give multiple release. Optionally, organopolysiloxane fluids may be employed along with the terpolymer release agent as a diluent.
