Product Description
Organic Polysilazane Mingyi 9283
Description
Mingyi 9283 is a liquid polysilazane with Si-N structural,
mainly function group is Me and modified fluorine groups
.
It is developed for room temperature cured hydrophobic coating systems.
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 good adhesion to substrate. Add appropriate catalyst in the resin can promote Si-H and Si-NH-Si reaction, after curing resin can generate three-dimensional cross-linked structure, giving the material good mechanical properties.

Mingyi 9283 has excellent hydrophobic property as contain fluorine group, keep the colorless transparent coating with good transmittance more than 95%.
Mingyi 9283 has low viscosity and good adhesion, can be applied to various types of substrates by smearing, dipping, spraying, brushing and other methods, the main substrates are metals, alloys, glass, paint films and plastics (such as PP, PC, PVC, PMMA), etc.

Notes
① Solid content of Mingyi9283 is 10%, could be customized as customers’ requirements.
② The heating curing process of Mingyi 9283 is operated after surface dried, curing temp. is 60℃-200℃. The totally cured time will be shorten as the temp. increasing.
③ The hydrophobic angle of cured Mingyi 9283 coating is stable at 115°, it could keep around 109° after heating with 350℃ in 1hour.
④ The operating temp. of Mingyi 9283 is related to the coating thickness, the higher thickness, the better protection, but the coating is easy to be crack in high. Temp.
