IMS Rigidiser

IMS Rigidiser is a colloidal silica compound for treating surfaces of fiber products to provide a degree of surface hardness and resistance to erosion. IMS Rigidiser is stabilized against freezing during exposure to cold; however freezing should be avoided.

– Increases surface hardness and resistance to erosion.
– Easily applied by brushing or spraying
– Freeze Resistant


– Surface coating for ceramic fibre blanket and modules exposed to high velocity gases
– Surface treatment for vacuum formed fiber shapes to increase surface hardness

IMS Rigidiser is applied by brushing, dipping, rolling and spraying. IMS Rigidiser recieves its bonding action from the removal of physical water. Bonding may be accelerated by heating or over drying. Curing is a function of the size of the shape and its geometry.
