Finntalc M40LV by Elementis is a functional extender-based on hydrated magnesium
silicate. It is a pure, lamellar, coarse particle size talc, exhibiting stable color, very hydrophobicity, inertness, and softness. It is characterized by special low viscosity impact and reduced oil absorption.
- It is purified in a cascade of multiple flotation cells, resulting in a precise definition of the talc composition, making this natural product similar to a synthetic chemical.
- In combination with a precisely controlled particle size distribution, it ensures exact reproducibility in formulations.
- It provides good barrier properties, good corrosion resistance, outdoor durability and good sandability with reduced VOC emissions.
- It is used in adhesives and polyester putties.
- Finntalc M40LV has a shelf life of 5 years.
