フェノール樹脂、調製方法、鉱物繊維用のサイジング組成物及びその生成品

摘要

A liquid phenolic resin intended to participate in the makeup of a sizing composition for mineral fibers is essentially composed of phenol-formaldehyde and phenol-formaldehyde-glycine condensates. A process for the manufacture of the resin, the sizing composition including the resin and the insulating products based on mineral fibers sized by means of the abovementioned sizing composition are presented.
