摘要

The preparation of Binders based on phenol formaldehyde Resin melamine formaldehyde and extended with a cyclic Urea formaldehyde Prepolymer as products prepared using Binders.More particularly, The Invention estu00e1relacionad with a cyclic urea Prepolymer comprising urea, formaldehyde and Ammonia or a primary Amine whichWhen added to a base Resin phenol formaldehyde Binder results in a useful for the Manufacturer of many articles.The prepolu00edm ero of the Binder is cyclical with a molar ratio of urea urea: formaldehyde, Ammonia or primary Amine, approximately 0.1 to 1.0: 0.1 to 3.0: 0.1 to 1.0.
