In order to formulate a paint binder for emulsion paint formulation, Urea formaldehyde resin was reactively blended with various concentrations (10-70 percent) of cassava starch. Some physical properties and the emission of formaldehyde from the blended resin have been investigated. Initially, viscosity decreased before a gradual increase was noted with an increase in the concentration of starch. With cassava starch content in the blend, refractive index and elongation at break increased initially but gradually decreased. As the inclusion of starch … Continue reading “Impact of Starch Addition on Properties of Urea Formaldehyde/Starch Copolymer Blends for Application as a Binder in the Coating Industry”
