POLY (VINYL ALCOHOL) - BASED FORMALDEHYDE-FREE CURABLE AQUEOUS COMPOSITION |
摘要 |
A formaldehyde-free curable aqueous composition containing polyvinyl alcohol, a multi- functional crosslinking agent, and, optionally, a catalyst. The composition may be used as a binder for non-woven products such as fiberglass insulation. The non-woven products are formed by contacting the formaldehyde-free curable aqueous composition with fibrous components and the mixture is cured to form a rigid thermoset polymer providing excellent strength and water resistance of the cured nonwoven product. |
