In 1967, Nitto Kasei commenced the manufacture and sale of stannous octoate as a foaming catalyst for soft polyurethane. We also began using organo-tin compounds - which had been used as PVC stabilizers - as polyurethane catalysts, expanding the possibility of organo-tin
compounds. Since then we have put the unique properties of various tin compounds to practical use as silicone bridging catalyst, esterification catalyst, epoxy hardening accelerator, glass coating agent, electrical conduction coating film, reaction protecting group,
rubber lubricant, paint coloring additive and so on, materials found in all sorts of products ranging from kitchen sponges to aerospace industry.
We have also expanded our activity to the fine chemical synthesis of pharmaceutical intermediates, preform for electronic materials and others.
We intend to ensure a stable supply of our existing products, while continuing to explore new possibilities in all areas for further progress and development.
Organo-tin compounds are available in mono, di, tri and tetra types (R4Sn, R3SnX, R2SnX2, RSnX3), of which the mono and di types are mainly used for industrial applications.
Nitto’s inorganic metal catalysts are widely used as bridging catalysts essential for urethane and silicone, and as esterification catalysts.
Widerange applications of inorgano-tin compounds include ceoxidizers, electric conduction film, glass-protecting film and ceramics. Nitto continues to develop new areas of applications for inorgano-tin compounds, to better meet the needs of the times.
