Uses and applications

What the substance is used for, by industry and function

Thermosetting resins, resin modifiers, chemical intermediate for pesticides, pharmaceuticals, and dyestuffs.

In industrial paints, addition of benzoguanamine to baking enamels based on melamine alkyd resins leads to increased gloss, elasticity, and stability toward alkali, used in the preparation of daylight fluorescent paints to increase their resistance to weathering, benzoguanamine is also an effective stabilizer for aqueous formaldehyde solutions, preventing the separation of formaldehyde polymers.

Used in amino resins for coatings because it provides excellent resistance to laundry detergent.

Industrial uses: Monomers, Other, Adhesion/cohesion promoter.

Consumer uses: Adhesion/cohesion promoter.
