The SIGMAFAST 210 HS Hardener is the B-component of the SIGMAFAST 210 HS two-component polyurethane system. It ensures the chemical reaction required to form a durable, resistant, and high-performance coating film.
Specifically formulated for the SIGMAFAST 210 HS base, it provides fast drying, excellent film cohesion, and reliable outdoor durability.
With its simple 10% mixing ratio, the hardener contributes to the coating’s strength, stability, and long-lasting anticorrosion protection, whether applied in the workshop or on-site.
