Fiber Coating · Repair Material
SD Tech's fiber coating and repair materials are manufactured from ceramic fibers and blended with organic and inorganic binders to form a viscous gel-like material. These fiber coating/repair materials are primarily used on the surfaces of ceramic fiber materials (such as ceramic fiber boards, modules, and vacuum-formed products). They reduce the rate of powderization of the fiber surface when in direct flame contact, improve the wind resistance of ceramic fiber module surfaces, and enhance chemical attack resistance.
1. Characteristic
- Delayed powderization of ceramic fibers
- Improved chemical attack resistance of ceramic fibers
- Improved resistance to high-temperature airflow
- Flame blocking
2. Use
- Suitable for use on ceramic fiber lining surfaces and other refractory surfaces
