Curable aqueous composition and use as fiberglass nonwoven binder
TLDR
In this paper, a formaldehyde-free curable aqueous composition containing a polyacid, a polyol and a phosphorous-containing accelerator was proposed for heat resistant nonwovens.Abstract:
This invention relates to a formaldehyde-free curable aqueous composition containing a polyacid, a polyol and a phosphorous-containing accelerator. The composition may be used as a binder for heat resistant nonwovens such as nonwovens composed of fiberglass.read more
