Used primarily in epoxy resin systems to initiate and control the curing process, enabling the resin to harden into a durable, chemically resistant solid. Commonly applied in coatings, adhesives, sealants, and composite materials for industries such as construction, automotive, and aerospace. Provides strong mechanical properties, good adhesion to substrates, and resistance to heat and environmental degradation. Also used in flooring systems and electrical insulation due to its excellent dielectric properties and long-term stability.
