Kasil SS Powder Potassium silicate PQ Corporation Extenders / Fillers >> Potassium Silicate ADHESIVE >> Water-based >> Inorganic (silicates) Because liquid silicates dehydrate (or dry), they can be used as glues to bond surfaces together. Silicates lose water to the air or to the surfaces being glued. As a silicate dries, its viscosity increases and it becomes tacky and sticky. Eventually the silicate dries to form a hard, glasslike bond. Silicates usually work well with porous or semi-porous surfaces, where the silicate can partially penetrate the surface. Silicates can also bond metal and glass, but surfaces must be roughened or attacked chemically to make sure that a good physical bond can be formed. To provide you with extensive formulating flexibility, PQ supplies potassium silicate in a wider variety of forms than any other manufacturer. Among them are liquid, flake glass, and hydrated powder products. PQ has been a leader in potassium silicate since its introduction to the North American market in 1942. Whether you manufacture welding rods, detergents, refractory binders, or specialty coatings—and no matter where on earth you make them—PQ offers the widest range of potassium silicate to meet your needs. Soluble Silicates in Bonding and Coating , Because of the low cost and versatile properties of PQ sodium and potassium silicates as coatings and binders, they are useful in a broad range of applications. Potassium silicate. Can be used as glue to bond surfaces together when dehydrates. Possesses increased viscosity, tackiness and stickiness when dries. Works well with porous or semi-porous surfaces, where it can partially penetrate the surface. Can also bond metal and glass (but surfaces must be roughened or attacked chemically to make sure that a good physical bond can be formed). Application: spiral and convolute tubes and cores, fiber drums, angleboard and cornerboard, corrugated board and other fibrous products (sisal, fiberglass, wood fabrics), paper/metal foil laminates, paperboard laminates.
