In this study, trimethylol urea from urea formaldehyde was modified with Hydroxylated African Locust Bean Seed Oil (HALBSO) (Parkia biglobosa) so as to satisfy some specific requirements for water-based binders. The copolymerization was carried out at different concentrations (10 - 60%). The results showed that the copolymer composite of trimethylol urea and hydroxylated african locust bean seed oil (TMU/HALBSO) is more water resistant, softer and more flexible and can compete favorably than some convectional paint binders. The blending at 50:50 has succeeded in reducing the emission level lower than the permissible level of 0.1 ppm. The different levels of interactions gave rise to polymers with different morphology and crosslink density. The density of the amino resin, decreases gradually with increase in HALBSO concentration and this trend is attributed to differences in the molecular features and morphology which influences the packing nature of resin molecules. TMU and HALBSO copolymer resin present itself as a good binder for the formulation emulsion paint.
