Urea Formaldehyde Resin Compositions, Methods of Making, and Uses Thereof

Abstract

Embodiments of the present disclosure generally relate to urea-formaldehyde (UF) resin compositions, methods of making, and uses thereof. In an embodiment, a method of forming a UF resin composition is provided. The method includes heating a first mixture comprising formaldehyde and a first amount of urea, introducing a bio-additive with the first mixture to from a second mixture, and heating the second mixture at a selected temperature while maintaining the second mixture at a selected pH. The method further includes introducing a second amount of urea to the second mixture to form a third mixture, and heating the third mixture to form a first product mixture comprising a UF resin composition. In another embodiment, a UF resin composition is provided. The UF resin composition includes a liquid UF resin and a bio-additive. The UF resin composition can optionally include a rheology- and/or strength-enhancing polymer, a methylated melamine-formaldehyde crosslinker, or both.
