Recently, a product named Full - Hydrogen Polysilazane Liquid Coating Material IOTA PHPS has emerged in the materials field. This inorganic (full - hydrogen) polysilazane coating, also known as Hydrophilic Super Hard Stain Resistant Nano - Coating Materials, has drawn attention for its unique properties and broad application prospects.

IOTA PHPS takes full - hydrogen polysilazane as its main component and is stored in a solvent after dilution. It boasts excellent solubility, short curing times, and diverse curing methods. It also has good adhesion to metal, ceramic, and polymer materials and can be converted into SiO2 at relatively low temperatures. In terms of technical parameters, it is a colorless and transparent liquid with a solid content of 20%. The solvent is n - butyl ether, and its liquid and cured densities range from 1.16 - 1.31g/ml and 1.6 - 2.0g/ml respectively.

Its curing mechanism mainly occurs through the hydrolysis of Si - N bonds. The curing conditions are flexible. It can be cured at room temperature for over 7 days or through moisture curing at 90% humidity and 150℃ for 2 hours. The cured coating has excellent properties. Composed mainly of SiOx, it has a thickness of over 100nm. Its hardness ranges from 3 - 10GPa under different curing conditions, with a pencil hardness of up to 9H (Zhonghua). Its transparency exceeds 90%, and its adhesion is Grade 0. It can withstand temperatures of 800℃ and has strong rust, alkali, and salt - water resistance. Although its acid (10% hydrochloric acid) resistance is relatively weak, it can last for about a month.

In application areas, IOTA PHPS can be used in building anti - graffiti, precious metal anti - corrosion, rail transit, semiconductor insulating layers, electronic circuits, plastic packaging for gas and water resistance, metal high - temperature oxidation resistance, and surface hardening coatings, showing great market potential.
