| Cera-Preg is a highly refractory air-setting inorganic surface rigidizer designed for refractory fibre products. It penetrates into the surface of the fibrous body, bonds the fibres together to achieve a harder more abrasive and erosion-resistant surface. Cera-Preg is stabilized against damage from freezing, owever repeated freezing should be avoided. Surface rigidizing is useful for preparing refractory fibre products to resist the abuse of contact with molten metals and other forms of mechanical abuse. This treatment should be approached cautiously as the surface resiliency of the refractory fibre body will be reduced and surface cracking may result in service. Applications: Cera-Preg may be applied on refractory fibre felts, blankets, vacuum-formed products and other high temperature insulations when rigidizing in necessary. It may be applied by means of spraying, brushing, dipping or rolling. An application method should be selected to enhance penetration 3.2 to 6.4mm (1/8" to 1/4") into the surface. When spraying, suitable respiratory protection and ventilation is required. Evaporation of water will fully cure Cera-Preg. Heating or oven-drying will enhance drying. Detailed handling instructions are on each container. Information provided by Morgan Advanced Materials |
