Description
IOTA 9283 is a liquid polysilazane with Si-N structural, mainly function group is Me and modified flurine 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.
IOTA 9283 has excellent hydrophobic property as contain group, keep the colorless transparent coating with good transmittance more than 95%.
IOTA 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) etc.

Notes
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, diethylene glycol dibuty 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/agon 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 in 100ml, 1L, 5L metal drums.
Clean
Proper cleaning methods are important. After use, quickly wipe down the tool with actone or mineral spirits.
Once IOTA-9150 is cured, ordinary solvents cannot be washed away. It can be treated with strong alkali such as sodium hydroxid 10% aqueous solution for more than 5 hours.
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.
