Organopolysilazane (room temperature curing coating resin) IOTA-OPSZ-9150
IOTA OPSZ-9150 is a transparent, batch-stable preparation new polysilazane resin, the structure is as follows:
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 is a transparent solid after curing.
OPSZ-9150 can anti-alcohol, ketones and other organic solvents after curing with.
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.
