Natural Additive for Reducing Formaldehyde Emissions in Urea-Formaldehyde Resins

open access: yesJournal of Renewable Materials, 2016
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.

Reduction of Formaldehyde Emission from Plywood Adhesive Filling a Ground Scallop Shell [PDF]

open access: yes, 2014
Scallop shells are disposed more than 200,000 ton per year in Hokkaido. Here we report effective uses for discarded shells as an additive of plywood adhesive because some plywood adhesives emit formaldehyde that leads to limit on its use.

Formaldehyde Emission in Micron-Sized Wollastonite-Treated Plywood Bonded with Soy Flour and Urea-Formaldehyde Resin

open access: yesApplied Sciences, 2020
Soy flour was partly substituted for urea-formaldehyde (UF) resin with different content to investigate its effect on formaldehyde emission in three-layer plywood panels. In each square meter of panels, 300 g of resin was used (wet weight basis of resin).
