APPLICATIONS

(Hydroxymethyl)-Urea and Bis(hydroxymethyl)-Urea are used as disinfectants, slimicide or algaecides for air, materials and equipment, whereas are not used for direct food or food contacts. Dimethylolurea is used in animal feeds to keep feed protein quality as it modifies tyrosine residues by decreasing microbial degradation. They are used as a preservative in metal-working fluids and processing systems. They are used to treat plywoods to increase hardness and fire resistance, and to form self-binding laminations and to treat textiles for better stiffness, shrink-resistannce for cottons, finishing, drying, sizing, and tanning. They are used as photographic film developers. They are used as intermediate for crosslinking agents for polymers and coatings.
