摘要:
A melamine-urea-formaldehyde resin modified with a cyclic urea prepolymer and sodium metabisulfite. Products prepared with the binder include wood composites such as particleboard and medium density fiberboard.
摘要:
A urea-formaldehyde resin modified with a water-insoluble anionic phosphate ester is used as binder in the preparation of glass fiber mats using a hydroxyethyl cellulose white water system. High tear strength glass fiber mats can be produced in a hydroxyethyl cellulose white water system using such a binder.

摘要:
A coated panel formed from a self-supporting cellulosic substrate and a top coating containing a thermoset resin having about 0.1-1.5 wt % free formaldehyde admixed with said resin; and (b) a thermoplastic polymer thoroughly admixed with said resin, wherein said thermoplastic polymer exhibits amine groups capable of reacting with at least some of the free formaldehyde under resin curing conditions. The coated panel can be embossed with decorative patterns such as wood grain without fracture of the coated surface or significant buildup on the press or embossing die surfaces.
