Trimer catalyst

Aliphatic and cycloaliphatic isocyanate high-efficiency trimerization catalyst Polyurethane has excellent physical and mechanical properties and chemical resistance. It is widely used in foam, coatings, elastomers, adhesives, leather, etc. Defects such as poor thermal properties, low softening temperature and low decomposition temperature limit its application in certain fields. Later, it was discovered that both aromatic and…
