The Uses of Benzoguanamine

In the manufacture of thermosetting resins, pesticides, pharmaceuticals and dyestuffs.

Preparation

Benzoguanamine closely resembles melamine in that reaction with formaldehyde gives methylol derivatives and then resinous condensates. Butylated benzoguanamine-formaldehyde resins have found some use in surface coatings. In a typical preparation, benzoguanamine (1 mole) is heated with formalin (3 mole formaldehyde) at pH 8.3 and 70-80°C until the guanamine has dissolved. n-Butanol (9 mole) and a small amount of hydrochloric acid are added and the azeotrope distilled off until removal of water is complete. Like their melamine counterparts, butylated benzoguanamine-formaldehyde resins are most commonly used in admixture with alkyd resins. The resulting coatings are very similar to those based on melamine but they show improved resistance to alkalis.

Flammability and Explosibility

Non flammable
