Boron Nitride Cera Patch Putty
Description
Boron Nitride Cera Patch is a unique trowelable putty for patching, repairing, and filling any fissure, crack or defect in refractory materials—leaving a non-wetting layer for molten metals, glasses, slags/drosses. It contains no RCF (Refractory Ceramic Fiber) and is not sensitive to freezing like other ceramic repair products. After applying and drying with no cure required, Cera Patch uniquely expands when heated up to the use-temperature
Specs
- Uses Boron Nitride for best non-wetting and is non-reacting with molten aluminum and its alloys or drosses
- Smoothly applies and spreads easily
- Dries in minutes at room temperature
- Expands to fill the damaged areas: does not sinter, shrink or crack with thermal cycling
- Excellent non-wetting, strength, hardness, and toughness that prevents molten aluminum from reacting or undercutting any coated or filled regions
- Stops metal penetration
- Long life of the repaired areas due to non-reaction/non-wetting
- High adhesion to all refractory types (dense or porous) without chipping or flaking
- Fills fissures, cracks, seams, and joints
- Not sensitive to freezing
