Recently, a material named Organic Polysilazane IOTA 9283 has drawn significant attention in the chemical industry. This liquid polysilazane, which contains a silicon - nitrogen structure and has methyl and fluorine - modified functional groups as its main components, is specifically designed for room - temperature - curing hydrophobic coating systems, showcasing unique performance advantages.

IOTA 9283 features Si - NH - Si bonds, allowing it to cure at room temperature. The curing process mainly involves the hydrolysis and oxidation of Si - NH - Si. Meanwhile, the Si - NH - Si bonds can react with the -OH groups on the surface of the substrate, resulting in good adhesion to the substrate. By adding an appropriate catalyst to the resin, the reaction between Si - H and Si - NH - Si can be promoted, forming a three - dimensional cross - linked structure and endowing the material with excellent mechanical properties. Additionally, the presence of fluorine - containing groups gives IOTA 9283 excellent hydrophobicity, and the cured coating is colorless and transparent with a light transmittance of over 95%.

This material has low viscosity and good adhesion. It can be applied to various substrates such as metals, alloys, glass, paint films, and plastics (e.g., PP, PC, PVC, PMMA) through multiple methods including coating, dip - coating, spraying, and brushing. Its cured coating is hydrophobic, has a short curing time, and offers diverse curing methods. It also has antioxidant, anti - corrosion, and easy - to - clean properties, with strong adhesion to metals and ceramics.

In terms of applications, IOTA 9283 has a wide range of uses, including coatings, adhesives, non - combustible composite materials, polymer - based composite materials, glass and abrasive tool fields, as well as areas requiring hydrophobicity and low surface tension for easy cleaning. It is believed that IOTA 9283 will bring new development opportunities to related industries.
