Our History

In 1924 Mr. I. D. Blumenthal was a traveling salesman in need of repair to his car's radiator. A local tinsmith in Charlotte, North Carolina repaired the radiator with a "magic powder". Impressed with the product, I.D. teamed with the tinsmith and SOLDER SEAL became the first product of Radiator Specialty Company. His brother, Herman, joined the company in 1938 to make it a family-run business. When I. D. passed away, Herman became Chairman of the Board, and likewise, later his other sons, Alan and Sam, each took responsibility for running the business at separate times.


Today RSC Chemical Solutions continues to serve the automotive, hardware and industrial markets through brands trusted for decades by trade professionals and serious DIYers.
