Evaluation of post-added ester and/or urea as a formaldehyde scavenger in UF resins used to bond southern pine particleboard
Three-layer particleboards made of southern pine were bonded with urea-formaldehyde resins containing post-added ester and/or urea. The ester was a water-soluble active methylene compound [(2-hydroxyethoxyethyl) acetoacetate], which was added to […]
