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.
