南通Paint grade talc slag

Characteristics of coating grade talc slag: high whiteness, strong hiding power, can improve fluid performance and prevent precipitation; Increase the covering power, increase the adhesion and weathering resistance; Improve the suspending, dry, waterproof and chemical resistance of the coating. At the same time, it can reduce the amount of titanium dioxide and reduce the production cost. Make the putty connect well, low oil absorption, good gloss.

Applicable fields:

Suitable for water - based industrial coatings, such as inner and outer walls.

Coating grade talc slag (TL)

Usage: used for white body pigment, water base, oil base, resin industrial paint, low paint, protective paint

Molecular structure diagram

This product is a mineral talc of magnesium silicate and mineral talc. Its main component is magnesium silicate containing water. After crushing, it is treated with hydrochloric acid, washed with water and dried.

The paint is made of talc

The main component of talc is hydrated magnesium silicate, molecular formula

For Mg3 [Si4O10] (OH) 2. Talc is a monoclinal system. The crystal is a pseudo - hexagonal or diamond - shaped sheet, occasionally seen. It is usually a dense mass, leaf, radial and fibrous aggregate. Colorless transparent or white, but light green, light yellow, light brown or even light red due to a small amount of impurities; The cleavage surface is of pearl luster. Hardness 1, specific gravity 2.7 ~ 2.8.

Characteristics of talc for coating

Talc soft, its for 1 ~ 1.5 mohs hardness coefficient, have slippery feeling, {001} cleavage is extremely full, easy to split into slices, natural rest Angle is small (35 ° ~ 40 °), very solid, the surrounding rock of silicide and petrochemical magnesite, lingmei rocks, lean ore or dolomitic marble, with a few solid medium, generally are not solid, joint, crack development, physical and mechanical properties of the ore and surrounding rock is a big influence on mining process.

Talc with lubricity, sticky, flow resistance, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good luster, strong adsorption force and other excellent physical and chemical properties, due to the crystallization of talc is a layered structure, so the easier to split into flake trends and special lubrication, if the content of Fe2O3 high will reduce its insulation.
