AT 4400 - THERMAL PROTECTION COATING
AT 4400 - Thermal Protection Coating is specifically formulated to create a thermal barrier for high temperature applications. AT 4400 is effective up to temperatures of 1200°F (648°C). Coating may be applied ultra-thin (3-6 microns) and has excellent adhesion to a wide range of substrates. It is an easy to apply single component coating with a quick drying time. AT 4400 may be used as a stand-alone insulation coating or as a topcoat on AT 4410 High Temperature Thermal Protection Coating. Multiple layers of AT 4400 coating may be applied until the overall desired insulation performance is achieved.
Proudly manufactured in the USA.
- Excellent insulation/thermal barrier.
