Product Sheet
General Description:
Curramix 3500 is an advanced multi-part low temperature-cure anti-coking ceramic coating system designed specifically for high temperature metal substrates and components. This coating exhibits state of the art coating technology with exponential improvements in thermal cycling and anti-coking properties. Designed to withstand extreme temperatures up to 750°F, (400c). Ideally suited for heat exchanger tubes, tube sheets, channels, exchanger components and crude heaters. Maintains repellency at 750f, (400c). Can be done in-situ.
Benefits:
- Excellent Hydrophobic & Oleophobic properties
- Excellent foul release.
- Reduction in drag
- Coating surface remains smooth even at high temperatures.
- Excellent adhesion
- Thermoshock resistant
- Minimal Porosity
- Resists micro-cracking & spalling
- VOC exempt
