  • Applications

    Benzoguanamine (CAS 91-76-9) is primarily used as a reactive intermediate and crosslinking agent in aminoplast resin chemistry, notably in melamine-formaldehyde and benzoguanamine-formaldehyde systems. It is employed in industrial coatings and inks to improve hardness, chemical resistance, and heat stability; in decorative wood laminates and veneer papers based on benzoguanamine-formaldehyde resins; as a building block for specialty polymers and thermosetting materials; and as a component in adhesives for wood panels and packaging. Depending on the formulation, it may act as a curing or crosslinking agent in reactive resin systems, including certain epoxy-amine formulations.
