摘要:
A moldable article comprising a woollike mass of intermeshed glass fibers bonded to one another at points of contact by a phenolic binder. The binder is substantially dry and curable, and comprises from 40 percent to 91 percent of a curable phenolformaldehyde condensate, from 4 percent to 40 percent of urea and from 5 percent to 45 percent of dicyandiamide. Preferably, the binder additionally contains a thickening agent, as well as a siloxane or other release agent and emulsified petroleum oil to minimize sticking and resin build-up during molding of the article.
