Description: Alumina enriched ceramic fibre in extrudable plastic form, supplied wet, ready to use, in mastic tubes. Very easily applied to any surface or crack.
Applications: High temperature insulation plugging of furnace holes, heat shields, burner cores, thermal shock protection, Furnace hoods, preheater lids, ladle lids, seating surfaces high gas flow areas of fibre lined furnaces, repair of cracks and joints protection of equipment, repair of shrinkage in fibre linings. Upgrading of linings for thermal efficiency or faster cycle times. Repair of broken element holding lips. Sealing of kiln and furnace doors.
Properties: Very low thermal conductivity, Electrically insulating, Very low density; 1,2g/cm³ wet, 0,6g/cm³ fired. Resistant to high gas velocities. Low shrinkage; normally 12% but all taken up in the thickness of the layer, therefore no cracks. Extreme thermal shock resistance. Very low thermal mass. High reflectivity. Low permeability compared to fibre blanket or modules.
Rapid commissioning. Excellent adhesion to all surfaces. Minimal anchoring required. High strength.
Installation:Fibre Mastic is supplied wet in 300ml plastic mastic tubes. It can be taken out and remixed or thinned down with water, or it can be ordered softer for injection. Cut the nipple off the tube, screw on the nozzle place it in a mastic gun. (±35 in hardware store) Cut the nozzle to give the desired flow diameter.
Onto brick; Blow dust off and squeeze on.
Insulating firebrick or very porous surfaces: Rub a thin layer on very firmly before builing up the profile.
Ceramic fibre: Over fresh fibre, softening by water dilution may help. You can order mastic in 10kg buckets.
Door seals: Plaster a narrow strip onto one surface, cover with fibre paper and close the door to press the Fibre Mastic into the exact thickness required.
