IOTA OPSZ 1800 Heat Curable Coating Resin(Organopolysilazanes OPSZ)
Description:
1. Enables the heat-curable coatings capable of withstanding operating temperatures of 1000 °C or above.
2. Supplied as a 100% "solids" liquid of low viscosity which rapidly solidifies upon heating to 200°C.
3. Solidification can be achieved at lower temperatures with the addition of a free radical initiator such as dicumyl peroxid1.
4. With the free radical initiator employed, cure from liquid to solid can be accomplished in times ranging from 1 to 90 minutes over a temperature range of 100°C to 180°C.
5. The peroxides are typically dissolved in solvent free polymer at the 0.5 to 1.0wt% level based on the weight of polymer employed.
6. Cure without the use of a peroxide can be effected by heating to 200 - 250°C.
7. For ultra-high temperature formulations, the coated part is then heated to at least 425°C to promote conversion of the polymer to ceramic.
8. Depending on the exact formulation, the resulting coatings are then durable at peak use up to temperatures of 1800°C.
Formulation and Application:
Typically added at 10 - 60 wt. % and is compatible with a wide array of solvents including alkanes, aromatic hydrocarbons, ethers, ketones, esters, etc.
Heating to temperatures above 700°C converts the resin to a ceramic.
High Temperature Ceramic Coatings.
Thermally Stable Anticorrosive Coatings.
Non-stick Coatings.
