Its low-viscosity formula allows easy application via brushing, spraying, or dipping, curing within 24 hours. Ideal for industrial uses such as forges, kilns, and furnaces, it extends insulation life and boosts thermal efficiency while reducing harmful particle release. ## Description Rigidizer is a Colloidal Silica Compound, that can be used as a cohesive agent for various fireproof materials which are used for insulation across various industries. This is widely applied for treating the surface of ceramic fiber materials like boards, blankets, vacuum-formed components, and modules for increasing the hardness and erosion resistance of the surface. We also deal in a wide range of quality ceramic fiber products like Ceramic Fiber Blanket, Board, Bricks, Paper, Ceramic Wool, and plenty more. Product Value Good Mechanical Strength: Rigidizer is used for surface treatment of the ceramic fiber materials to increase its resistance to abrasion, thermal shock resistance, and volume stability providing durability and good mechanical strength to the surface. High Insulating Value: This coating can withstand temperatures up to 2300F providing high insulating value to ceramic fiber materials and extending their life by increasing erosion resistance of surfaces that are subject to high-velocity gases. Enhance Efficiency: Ceramic fiber materials coated with rigidizer reflects more heat, thus improving their thermal efficiency and giving you better results. Safety: This rigidizer when applied prevents the particle to fall off from the surface and also reduces the spread of harmful airborne particles that impact your health. Applications - Surface Coating of Ceramic Products exposed to high-velocity gases & flame impingement. - Cohesive agent for the ceramic blankets, boards, paper, and for making other composites too. - For the surface treatment of vacuum-formed shapes to increase firmness and solidity of its surface. - Mix with water 1:1 makes 32 Oz. - This is enough to rigidized 1 piece of 24”x24” ceramic fiber blanket Review: Easy to mix. I’d certainly recommend using a hand spray bottle to apply it rather than a brush. It seems to rigidise my thermal kiln blanket well and is economical. Review: Works great perfect for prep on isolation and activities fast and strong ## Features - HIGH TEMPERATURE INSULATION - This coating increases the insulation value of ceramic fiber materials and can with stand temperature up to 2300F - HARD SURFACE FINISH - Rigidizer makes the surface finish after application with increase resistance to mechanical abrasion and helps flexible ceramic fiber material from being too flaky - EROSION RESISTANCE - Rigidizer increases surface erosion resistance for surfaces exposed to high velocity gases - EASY TO APPLY - Because of it low viscosity its application on ceramic fiber materials becomes very simple. It can be applied with brushing, spraying or dipping. It takes around 24 hours for curing post application. (Don't keep the lid open when not in use for better preservation as it starts freezing when it comes in contact with air) - WIDE APPLICATION - This rigidizer is extensivly used in varied fields for surface coating of ceramic fiber insulation used in Forges, Foundry, Furnace, Stove, Oven, Raku, Kiln and many more ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B84XT8VN | | Item model number | RCB-12 | | Manufacturer | Spectra Overseas | | Package Dimensions | 18.59 x 6.81 x 6.71 cm; 630 g | ## Product Details - **Brand:** REFRATECH - **Item form:** Liquid - **Material:** Ceramic - **Special features:** Heat Resistant - **Specific uses for product:** Forges, Foundry, Furnace, Stove, Oven, Raku, Kiln, Ceramic fiber insulation ## Images ![Rigidizer for Ceramic Fiber Coating, 2300F Rated, Fireproof Insulation Surface Coating for Ceramic Fiber Blanket Boards Wool – 16 Oz Rigidizer - Image 1](https://m.media-amazon.com/images/I/71hLRDM3rpL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this adhere to steel?** A: No **Q: Can this be sprayed on the inside of a woodstove in place of fire brick?** A: Yes **Q: How much will this 16Oz bottle coat?** A: I had it for a whole 24"x 156" roll.
