Talc range & mullite
More ways to improve your mix
What other minerals offer innovations to your industry? Four should be front-of-mind for manufacturers looking to up their game.
The first is talc, the softest of all minerals. Chemically inert and available in macro- or micro-lamellar crystal shapes, when talc is added to adhesive and sealant binder systems it improves properties such as rheology, cracking, and sanding resistance in epoxies and putties. Our talc brands include Luzenac, Mistrobond and Stealene.
Bentonite also produces a range of results. A product of weathered volcanic ash, bentonite can be used to adjust low shear viscosity in adhesives due to its absorbent properties. We produce a range of sodium-modified bentonites perfect for this application.
For those who need to increase the electrical and thermal conductivity of adhesives and elastic bonding materials, our range of conductive carbons are ideal, notably our Ensaco grades.
Finally, there’s mullite, a rare silicate mineral formed during contact metamorphism of clay minerals. It’s highly resistant to heat (up to 1,200°), and its low, uniform thermal expansion rate gives it excellent resistance to thermal shock, while its rough particles improve keying properties for clay or chemical bonding.
