Inorganic hardening agent Rigidizer
It is used to strengthen the surface of high-temperature insulating wool products with a liquid inorganic hardener that disperses ultra-fine particles of anhydrous silica in water.
The strength appears by spraying or dipping this product and then drying and heating it. ■Usage Instructions To cure the inner lining surface of high-temperature insulating wool, first dilute the rigidizer concentrate with clean water to about twice its original concentration. Next, using a hydraulic spray with a pressure of 1-2 kg/cm² (pressure tank type or pump type), uniformly spray the diluted liquid at a rate of 2 liters per square meter. Smooth the sprayed surface with a wooden trowel or roller. After leaving it for at least 8 hours, drying or heating will yield a good curing surface. Please note that if the concentrate is sprayed directly, a thin curing film will form on the surface of the blanket, which can easily peel off and will not achieve the intended purpose. Additionally, this product is not toxic, but it can adhere to the skin and is not easily removed, so please use thin rubber gloves. If it accidentally comes into contact with the skin, wash it immediately with water or warm water.
