Talcum powder in the field of coatings
Talc, scientific name: hydrated magnesium silicate, chemical formula: Mg3[Si4O10](OH)2, by its unique layered structure, so that it has a special lubricity and chemical stability, but also has a soft, strong adsorption and other excellent physical properties.
It is widely used in the field of coatings:
●Automotive putty atomic gray
●Primer for steel structure
●Railway primer and medium paint
●Latex paints for interior and exterior wall coatings
●Polyurethane waterproof coatings
●High temperature silicone coatings, etc.
Product Application Characteristics:
Automotive Putty Atomic Gray: Adding talcum powder as a skeleton increases sandability and improves construction performance.
Steel structure primer: high proportion of talc can improve the paint precipitation, delay the diffusion of corrosive substances and effectively improve the protective effect, and at the same time can improve the mechanical force of the coating film and re-coating properties.
Railway transportation coating: a certain amount of talcum powder can improve the primer sanding, penetration; enhance the toughness of the middle coating, improve the phenomenon of sanding sticky sandpaper, improve the leveling of the middle coating, so that the overall appearance of the film is further enhanced.
Interior wall emulsion paint coating: a certain amount of talcum powder can effectively improve the construction and leveling of emulsion paint coating; and high hardness chemical stability, but also can effectively improve the corrosion resistance of the coating, scrub resistance.
