PortuguêsFibrepatch - Refractory Fibre Mastic
ApplicationFibrepatch is an air setting high alumina insulation refractory supplied in a plastic, ready to use form. Based on ceramic fibres, its high workability enables it to be trowelled, hand moulded, injected or gunned. It will readily adhere to most surfaces. ClassificationFibrepatch will air dry to a lightweight strong hard mass. Forced drying must be below 100°C taking care to allow for the escape of moisture. Fibrepatch is thermally stable up to 1000°C having low shrinkage and high resistance to thermal shock. It is not advisable to use Fibrepatch beyond a maximum service temperature of 1260°C (=MST), as shrinkage increases rapidly. The melting temperature of the ceramic fibre is 1790°C. |

Packaging & Storage
Fibrepatch is supplied in 4 litre tubs. Use in rotation. Exposure to air and prolonged storage will result in a firmer mass. A useable shelf life of 3 months may be expected during which any reduction in workability can be regained by hand mixing in the container. Slight drying-out can be recovered by the addition of small amounts of water and remixing but this is not recommended.
