Natural additives for reducing formaldehyde emissions in urea-formaldehyde resins

open access: yes, 2015
This work studies the use of soy protein as a natural formaldehyde scavenger in wood particleboard production. The protein is incorporated in two forms: a) as a powder, during the blending process of wood particles with urea-formaldehyde binder resin, and b) as an aqueous solution, added at different times during resin synthesis.

Influence of uron resins on the performance of UF resins as adhesives for plywood

open access: yesMaderas: Ciencia y Tecnología, 2012
Uron resin, a kind of urea-formaldehyde (UF) resin containing much more uron structure, were prepared. Several modified UF resins were obtained from mixing uron resins with normal UF resins as well as synthesizing UF resin with uron resin as raw material.
