Application characteristics of talcum powder in the field of coatings
Talc, scientific name: hydrated magnesium silicate, chemical formula: Mg3[Si4O10](OH)2, due to its unique layered structure, it has special lubricity and chemical stability, as well as softness and adsorption, strong and other excellent physical properties. Widely used in the field of coatings:
●Automotive putty
●Primer for steel structure
●Railway primer and primer paint
●Latex paint for interior and exterior walls
●Polyurethane waterproof coating
●High temperature silicone coating and other products
Application features:
Auto putty: Add talcum powder as skeleton to increase sandability and improve workability.
Steel structure primer: high proportion of talc powder can improve the precipitation of the coating, delay the diffusion of corrosive substances and effectively improve the protective effect, and at the same time can improve the mechanical strength and recoatability of the coating film.
Rail transit paint: A certain amount of talc powder can improve the sandability and permeability of the primer; enhance the toughness of the middle coat, improve the phenomenon of sanding and sticking to the sandpaper, improve the leveling of the middle coat, and further improve the overall appearance of the paint film.
Interior wall latex paint coating: a certain amount of talc can effectively improve the construction and leveling of latex paint coatings; and with high hardness and good chemical stability, it can also effectively improve the corrosion resistance and scrub resistance of the coating.
