Product Description

Product Name: Organic Polysilazane IOTA 9150

IOTA 9150 is a liquid polysilazane with a Si-N structure, the main functional bonds are Me. It is developed for room temperature cured and adjustable curing time 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 9150 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

• Surface curing time of IOTA 9150 could be customized as customers' requirements. The surface dry time are confirmed for the same items. For example:

1. IOTA 9150-8545 in 20ºC-40ºC, the thickness is 10μm-100μm, surface dry time is 15min-30min.
2. IOTA 9150-8525 in 20ºC-40ºC, the thickness is 10μm-100μm, surface dry time is 30min-45min.
3. IOTA 9150-8545 in 25ºC, humidity is 60%, thickness is 25μm, surface dry time is 20min.
4. IOTA 9150-8545 in 25ºC, humidity is 60%, thickness is 100μm, surface dry time is 28min.

• The heating curing process of IOTA 9150 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 9150 is related to the coating thickness, the higher thickness, the better protection, but the coating is easy to be crack in high temperature.

Application details
Case 1: car coating

Coating thickness	Application	Coating methods
3-8µm	Car coatings	Rubbing/Brushing

Effect: Car surface brightening, anti-corrosion, anti-graffiti, anti-scratch
Recommend solid content: 10%-20%
Dilution (for example IOTA 9150-8545):

1. Solvent: adjustable according to customers' requirements.
2. Ratio: i.e: IOTA 9150-8545: Solvent=1:3-8, prepare the proper solvent, add into IOTA 9150-8545.
3. Sealed with High purity argon/nitrogen in metal container.

How to use?

1. Take the prepared polysilazane solvent, dip with clean non-woven fabric, and then wipe evenly on the surface of the car that has been treated.
2. After operated, place in room temp. for 30-60min, heat in 60-80°C for more than 3hours to totally cured.

Case 2: Anti-corrosion coating

Coating thickness	Application	Coating methods
10-15µm	Surface protection of radar and other equipment	Spraying/Brushing

Effect: The transparent coating does not affect the surface camouflage texture effect of radar and other equipment, and provides anti-corrosion, anti-graffiti, anti-scratch and certain hydrophobic and high-temperature resistance effects.
Recommend solid content: 15%-25%
Dilution (for example IOTA 9150-8545):

1. Solvent: adjustable according to customers' requirements).
2. Ratio: IOTA i.e:9150-8545: Solvent=1:2-5, prepare the proper solvent, add into IOTA 9150-8545.
3. Sealed with High purity argon/nitrogen in metal container.

How to use?
1. Take the prepared polysilazane solvent, evenly sprayed on the surface of the substrate of radar and other equipment.

1. After operated, place in room temp. for 60min, heat in 45°C for 2hour, 125°C for 1hour.

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 dibutyl 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.

Storage
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/argon 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.

Clean
Proper cleaning methods are important, quickly wipe down the surface with acetone or mineral spirits after use.
Once IOTA 9150 is cured, the coating cannot be washed away by solvent. It can be treated with strong alkali such as sodium hydroxide 10% aqueous solution for more than 5 hours.

Package
Packed with metal container in 100ml, 1L and 5L.

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.
