Cyclic urea-formaldehyde prepolymer-modified melamine-containing resins, and use in binders for cellulosic-based composites

摘要

A melamine-containing resin modified with a cyclic urea prepolymer comprising urea, formaldehyde and ammonia or a primary amine. The prepolymer-modified melamine-containing resin provides useful binders alone, or when combined or coreacted with other resins. Products prepared with the binder include wood composites such as particleboard and medium density fiberboard.
