Additional minerals

Additional minerals

Imerys offers a wide portfolio of additional minerals which can provide interesting specific functions in adhesive and sealant applications.

Talc

Talc is the softest of all minerals, hydrophobic, chemically inert and available in macro- or microlamellar crystal shapes. Each crystal type confers different interesting properties to adhesive and sealant binder systems.
Imerys talcs are suitable additives for improving properties such as rheology, cracking, and sanding resistance in epoxies and putties.

Brands include: Luzenac, Mistron®, Mistrobond®, Stealene®

Bentonite

Bentonite originates from the in-situ weathering of volcanic ash and consists primarily of montmorillonite, a fine particle sized hydrous aluminum silicate and one of the three layer clay materials.  When brought into contact with water, bentonite swells to several times its original volume. 
Imerys sodium modified bentonites can be used to adjust low shear viscosity in adhesives.

Conductive carbons

Imerys conductive carbons such as our Ensaco® grades can be used to increase the electrical and thermal conductivity of adhesives and elastic bonding materials.

Mullite

Mullite is used in formulations mainly for its resistance to high temperature (up to 1200°C).
The low, uniform thermal expansion rate of Imerys Molochite
® gives it excellent resistance to thermal shock, while the rough particles gives excellent keying properties for clay or chemical bonding.

We offer a full range of custom formulation and technical and process support services to help you match the right mineral grade to your application requirement.
