Biesterfeld has expanded its distribution partnership with Songwon CS to cover additional countries in Europe, strengthening its additives portfolio for paint and coatings, adhesives and related applications.

Effective immediately, Biesterfeld will distribute Songwon’s SONGNOX® CS antioxidant and SONGSORB® CS light stabilizer product lines in the Baltic States, Bulgaria, Bosnia and Herzegovina, Croatia, Kosovo, North Macedonia, Montenegro, Serbia, Slovenia, Ukraine and Romania. The two companies already cooperate in Italy, Austria, Poland, Portugal, Switzerland, Slovakia, Spain, the Czech Republic, Hungary and parts of Germany.

The stabilizer ranges are designed for use in coatings, adhesives, sealants and reaction resins, helping protect formulations from light and heat exposure while supporting consistent product performance over time. According to the companies, the expanded agreement supports growing demand for high-performance stabilizers in emerging and established European markets.

“Biesterfeld contributes market knowledge and technical expertise, while Songwon CS provides a broad portfolio. Together, we ensure that formulators receive the best possible complete solution for their specific applications,” said Robert Geffken, Product Manager at Biesterfeld.

Fabio Giuntoli, Sales Manager Coatings EMEA at Songwon CS, said the expanded partnership will allow the company to reach customers more efficiently in new regions while supporting localized technical service and supply.

The agreement further positions Biesterfeld to support formulators seeking stabilizer solutions that align with regulatory requirements, process efficiency goals and long-term performance expectations.
