Abstract

The blending of dimethylol urea (DMU) and hydroxylated black seed oil (HBSO) was studied in this work. The FTIR spectroscopy of the pure DMU and DMU/HBSO showed that chemical interaction took place. Some of the physicochemical parameters such as melting point, gel time, moisture uptake, turbidity, viscosity, density, solubility, formaldehyde emission, and refractive index were investigated. Results of the composites showed remarkable improvements in formaldehyde emission, flexibility and softness, optical properties and water resistance compared to the hardness and brittleness, poor water resistance and formaldehyde emission associated with dimethylol urea. Therefore, this copolymer composite (DMU/HBSO) resin can serve as a potential binder for emulsion paint formulation.
