Application Method:
It is used in production of aminoplast resins such as urea formaldehyde adhesives, UF and MUF impregnation resins. It is used as anti-caking agent in the process of urea production. As an antiseptic in hospitals, cattle breeding centers, contaminated public places, sugar industries and sanitary detergents.
