Silicates bind particles together in applications such as briquetting, pelletizing, agglomeration, and coatings. As in paper adhesives, the dehydration of a liquid silicate results in a sticky glue that hardens as it dries. Liquid silicates may also be mixed with setting agents, however, to obtain binders that set faster and are water-resistant. Powdered silicates are also used, although they must be dissolved before they can provide binding power.
