Unifrax Fiberfrax® Rigidizer™ Inorganic Liquid Hardener

Rigidizer™ and Rigidizer™ W, inorganic liquid hardeners, have a temperature grade rating of 1260°C (2300°F). They are generally used to increase the durability and surface erosion resistance of Fiberfrax blanket and board products. Rigidizer W hardener contains an organic wetting agent to promote saturation into the substrate, whereas Rigidizer hardener tends to remain on the material surface of the product form to which it is applied.Typical ApplicationsRigidizer for surface hardening of other Fiberfrax product formsRigidizer W for saturating and rigidizing other fiberfrax product formsErosion-resistant coating for surfaces subject to high-velocity hot gasesInformation Provided by Unifrax I LLC
