The main role of talcum powder in water-based paint
Used as a filler to reduce the cost of paint, which is determined by the structure of talcum powder and its own low cost.
Increase physical and chemical properties and maintain the stability of the paint system. Because the molecular structure of talcum powder is layered, when used in paint, it can be evenly dispersed in the resin in a layered manner, and has good compatibility and complementarity of mechanical properties with the resin. Just like the steel structure mesh embedded in concrete, it can not only maintain the advantages of the paint itself, but also form an enhanced support structure with excellent mechanical properties to improve the physical properties of the product.
Increase the weather resistance and insulation of the paint. Due to its inactive chemical properties, it is also acid and alkali resistant and insulating. Adding it to the paint can also reduce the aging and weathering of the paint and improve the electrical insulation performance.
Used as an auxiliary matting agent. Due to its special structure, after the paint is added to the medium coating and the film is dried, the surface forms a diffuse reflection, which can be used as a matting agent and increase the stain resistance of the paint.
Provide paint anti-corrosion. Because talcum powder is a flaky structure, adding it to the paint can improve the protective effect by extending the diffusion path of corrosive substances in the paint film.
Increase the feel. This is because talcum powder has a greasy feel. When added to the paint, it can provide a special feel to the coating after the coating dries.
