PHENOL-BASED RESIN FOR THE PRODUCTION OF LAMINATES AND PROCESS FOR THE PREPARATION OF THE RESIN

摘要

A Mg compound-containing phenol formaldehyde resin neutralized to a pH-range of 7,5 to 5 which resin alone or together with a melamine formaldehyde resin can be made cure rapidly and whereby, when using an impregnated paper in the body portion of a laminate, the laminate can be impressed with a dynamic or static compression, at a high or low pressure at an increased temperature and whereby the paper can be pressed to the surface of a building board over a short pressing time.
