Borchers, a Milliken brand, announces the launch of Borchi® Kat 2115, a next generation
tin-free catalyst engineered for polyurethane coatings. This empowers formulators to meet demanding performance standards while advancing compliance and sustainability in line with evolving global regulations.

With increasing global regulations driven by regulatory bodies like the European Chemical Agency mandating stricter labeling on dibutyltin dilaurate (DBTDL) and 2- ethylhexanoate (2EH) in coatings, Borchi Kat 2115 enables manufacturers to transition to better-labeled, high-performance systems without sacrificing efficiency or durability.

Developed as a combination of neodecanoate metals, Borchi Kat 2115 delivers optimal reactivity and reliability while minimizing regulatory drawbacks.

“True innovation means delivering solutions that not only perform but also advance sustainability and compliance in our industry,” says Jeff Losch SVP and managing director for Milliken’s polymer solutions business. “The launch of Borchi Kat 2115 demonstrates our team’s commitment to developing next-generation technologies that help our customers meet evolving regulatory requirements and achieve their performance goals with confidence.”

Borchi Kat 2115 provides efficient reactivity and enhances durability properties compared to traditional tin and bismuth-based catalysts in 2K polyurethane systems. This next generation catalyst has been tested across a range of applications, including general industrial, protective and marine, and automotive refinish coatings.

Key benefits include optimal drying times, longer pot life, superior hardness, excellent corrosion resistance, and stable gloss/color retention.
