PREPARATION OF LIGNOCELLULOSIC-ISOCYANATE MOLDED COMPOSITIONS USING A TERPOLYMER OF A FUNCTIONAL POLYSILOXANE-ISOCYANATE-CARBOXYLIC ACID OR SALT THEREOF AS RELEASE AGENT |
摘要 |
In the compression molding of lignocellulosic composite articles, such as particle or flake board, in which polyisocyanate binder systems are employed, a terpolymer of a hydroxy- or carboxy- polysiloxane, an isocyanate and a hydroxyl substituted monocarboxylic acid or metal salt thereof is employed 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. |
