Product name:Organopolysilazane (room temperature curing coating resin) IOTA-OPSZ-9150
Description:
IOTA OPSZ-9150 is a transparent, batch-stable preparation new polysilazane resin
Description: The product has a unique Si-NH-Si bond, can be cured at room temperature, curing mainly involved in the reaction of Si-NH-Si hydrolysis and oxidation. While the Si-NH-Si bond and the substrate surface-OH easily react, and bring the substrate and good adhesion. Addition the appropriate catalyst in the resin can promote Si-H and Si-NH-Si reaction, after curing resin to form three-dimensional cross-linked structure, giving the material good mechanical properties, hardness can be as high as 9H.
OPSZ-9150 can anti-alcohol, ketones and other organic solvents after curing with.
OPSZ-9150 is a transparent solid after curing.
OPSZ-9150 is a one-component product. It is soluble in polar and non-polar solvents, such as ethers and alkanes, but can't be diluted with alcohol solvents or water.

Q: What is polysilazane?
A: Polysilazane is a polymer composed of elements such as silicon, nitrogen and hydrogen, and its molecular structure contains silicon-nitrogen bonds (-Si-N-). This polymer usually appears as a colorless or slightly yellow solid with special chemical properties and application characteristics.
Q: What are the main uses of polysilazane?
A: Polysilazane has important applications in some specific fields, including:
Ceramic preparation: used as polymer precursor, which can be converted into ceramic materials at high temperatures and used to prepare ceramic coatings, ceramic fibers, etc.
Composite materials: Matrix or reinforcement materials that can be used to prepare high-performance composite materials.
Q: What are the characteristics or advantages of polysilazane?
A: Polysilazane has some special properties, such as:
High temperature resistance: exhibits excellent stability under high temperature conditions.
Low dielectric: Has lower dielectric loss.
Ceramic conversion: can be converted into high temperature resistant ceramic materials under appropriate conditions.
Q: What is the preparation method of polysilazane?
A: Polysilazane is usually prepared by chemical synthesis. The preparation method may involve a multi-step chemical reaction process, including the reaction of silicon, nitrogen source material and polymerization catalyst.
Q: What is the role of polysilazane in ceramic preparation?
A: As a precursor material for ceramics, polysilazane can be converted into silicon-nitride ceramics under high temperature conditions. This ceramic usually has excellent heat resistance, chemical stability and mechanical properties. It is used to prepare ceramic coatings, ceramic fibers, high-temperature ceramics, etc.
Q: How environmentally friendly is polysilazane?
A: Polysilazane is generally considered a relatively environmentally friendly material, but its specific environmental protection needs to comprehensively consider the environmental impact of its preparation process, usage conditions and final application scenarios.
