Special for investment casting


                              Yuda silica sol and silicate are widely used in all walks of life due to their good adhesion, high temperature resistance, film-forming property, gelation, electricity charge, large surface area, non-toxic, tasteless and odourless characteristics. In addition to precision casting, catalyst industry, coating (architectural coating, casting coating, fire retardant coating, other coatings), refractory (refractory products, castable, mullite fiber, furnace lining) Civil Engineering (concrete, wharf, airport, pier, foundation, sediment reinforcement, cultural relics protection, etc.), anti rust and anti-corrosion (replacing phosphating treatment, anti-corrosion treatment, wet sand blasting, Besides heavy anti-corrosion coating materials, wall and floor functional materials, they can also be used in the following fields:
