Organic Polysilazane IOTA 9150K Description IOTA 9150K is a liquid polysilazane, it is developed for room temperature cured 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 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. IOTA 9150K 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), etc. IOTA 9150K has high activity, generally solid content is 50%, could customized as customers' requirements. |

Notes
The heating curing process of IOTA 9150K is operated after surface dried, curing temp. is 60ºC-200ºC. The totally cured time will be shorten as the temp increasing.
The operating temp. of IOTA 9150K is related to the coating thickness, the higher thickness, the better protection, but the coating is easy to be crack in high temperature.
compatibility
The product could be miscible with most non-polar solvents, such as alkanes, ethers, ketones, esters. Insoluble in alcohol and ether solvents, such as diethylene glycol dimethyl ether,tetraethyl ether Butyl glycol ether.
It's also miscible with a variety of resins, such as epoxy silicone resin, silicone resin, it will shorten the curing time and improve resin hardness when mixed with silicone resins.
Operation methods
Operating and storing in a dry, cool and well-ventilated environment, away from heat and fire sources, the recommended temperature is 0-20ºC.
The gloves, masks, etc. is necessary when taking the product.
Uncured product should not be placed close to fire sources, humid air, or water.
The container must be replace the air with nitrogen and completely sealed in time after use.
Unused product that has been formulated cannot be recycled and should be disposed of in accordance with local regulations.
Products beyond the shelf life can be used only after the retesting complied.
Package
Packed with metal container in 100ml, 1L and 5L.
Clean
Proper cleaning methods are important, quickly wipe down the surface with mineral spirits after use.
Once IOTA 9150K is cured, the coating cannot be washed away by solvent.
Precautions:
The storage environment should be dry, cool and well ventilated, away from heat and fire sources. The packaging container must be kept tightly closed and handled with care. The storage temperature should be kept between 0°C and 20°C, and the storage period is 12 months.
