Preparation of lignocellulosic composite articles using a functional polysiloxane release agent.

摘要

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 functional polysiloxane release agent on the mold surfaces to give multiple release. Optionally organopolysiloxane fluid may be employed along with the functional polysiloxane as a diluent.
