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 peroxide.

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.
