Frequently Asked Questions

Common questions about Talc in adhesive & sealants applications

Talc improves reinforcement, enhances barrier properties against moisture and oxygen, helps increase solid content, and provides UV shielding — all while being a soft, easy-to-process mineral filler.

The plate-like (lamellar) structure of talc particles creates a tortuous path that limits moisture and oxygen transmission through the adhesive or sealant film, significantly improving barrier performance and durability.

Yes. Talc improves workability, contributes to better sanding properties (important in automotive putties), and provides a smooth surface finish in the cured product.

Yes. Talc is compatible with polyurethane, epoxy, silicone, and solvent-based adhesive and sealant systems, delivering reinforcement and barrier performance across all these formulations.

Talc's lamellar structure helps shield the adhesive or sealant from UV degradation by physically blocking UV rays and reducing their penetration into the polymer matrix.

SUPER TALC is an ultrafine, high-purity grade offering superior smoothness and mechanical strength, while Micron Talc 2050 and 1030 are coarser grades suited for general-purpose applications with good reinforcement and barrier properties.
