Finntalc M15 is a hydrated magnesium silicate with the chemical formula Mg₃Si₄O₁₀(OH)₂, known for its high consistency and reproducibility due to its precisely controlled particle size distribution.

Finntalc M15 is used in a wide range of applications including interior and exterior paints, coatings for automotive and marine industries, and as a functional extender to improve properties such as abrasion resistance, weather resistance, and adhesion.

The purification process of Finntalc M15 involves multiple flotation cells, which tightens the talc composition and makes it similar to a synthetic chemical, ensuring exact reproducibility in formulations.

Finntalc M15 is a trademarked name, typically used in the context of industrial chemicals or products.

Unfortunately, detailed information about Finntalc M15 is not widely available in general sources.

If you have specific questions about its uses, properties, or handling, I recommend consulting the manufacturer's data sheets or product specifications.

Finntalc M15 is a hydrated magnesium silicate.

Finntalc M15 is a hydrated magnesium silicate with chemical formula of Mg3Si4O10(OH)2.

Finntalc grades are purified in a cascade of multiple flotation cells. 

This process results in a tight definition of the talc composition, making this natural product similar to a synthetic chemical. 

In combination with a precisely controlled particle size distribution, this ensures exact reproducibility in formulations. 

Finntalc M15 is a part of the most tightly defined talc product lines worldwide, with the highest consistency and reproducibility, and has 18% of the particle size <2 µm. 

Finntalc M15 has applications in interior flat emulsion paints, exterior flat emulsion paints, multi-purpose interior/exterior paints, flexible exterior wall paints, semi-gloss emulsion paints, outdoor wood paints, elastomeric coatings, silk and eggshell paints, general industrial protective coatings, heavy duty maintenance coatings, high solids-low VOC coatings, alkyd, epoxy, RU primers - solvent based, water based epoxies, ballast coatings, marine coatings, offshore/onshore coatings, automotive OEM-intermediate coatings, commercial vehicles, freight container, yacht paints, and gel coats.

Finntalc M15 by Elementis is floated, medium sized, laminar talc (Mg-silicate). 

Finntalc M15 is recommended for paints & coatings.

Finntalc is the second most popular filler, after calcium carbonate, used in the production of LFM. 

The hydrophobic surface and lamellar shape of talc particles give decorative lacquers many useful properties:

Improves abrasion resistance according to ISO 11998 and cracking, weather resistance, increases protection against external influences, water-repellent properties, easy to clean.

Promotes pseudoplasticity, improves rheological and thixotropic properties, prevents sedimentation, increases shelf life, improves coverage.

Provides better adhesion to the surface, irreplaceable in the composition of corrosion-resistant coatings.

Has an extremely stable quality, ideal for paint tinting systems.

Finntalc M15 is an ideal solution for exterior and interior paints - matte, semi-glossy, silky, and materials for exterior finishing of wooden and stone (concrete, brick) surfaces.

Finntalc grades are purified in a cascade of multiple flotation cells. 

This process results in a tight definition of the talc composition, making this natural product similar to a synthetic chemical. 

In combination with a precisely controlled particle size distribution, this ensures exact reproducibility in formulations.
