Main application fields:
Polyurethane industry (core application):
Role: It is one of the most crucial gel catalysts used in the production of polyurethane foam plastics (soft foam, hard foam, semi-hard foam, self-bonding foam). It is often combined with foaming catalysts to precisely control the balance between foaming and gelation.
End products: Automotive seats, furniture padding, building insulation boards, shoe materials, packaging materials, etc.
Synthesis of pharmaceutical and pesticide intermediates:
Role: As a strong organic base catalyst, it is used to promote various reactions such as esterification, alkylation, and cyclization, especially suitable for asymmetric synthesis and API preparation with strict requirements for alkalinity and steric hindrance.
Epoxy resin curing accelerator:
Role: As an efficient latent curing accelerator, it can significantly reduce the curing temperature of epoxy resin systems, accelerate the curing speed, and improve the thermal, mechanical, and electrical properties of the products.
Organic synthesis catalyst:
Role: As a multifunctional catalyst or ligand, it is used in reactions such as Knoevenagel condensation and Michael addition, improving reaction selectivity and yield.
Petroleum and natural gas processing: Role: As a component of a selective desulfurizer, it is used to remove hydrogen sulfide (H₂S) and mercaptans (RSH) from refinery gas and natural gas, thereby improving the quality of the gas.
