Royal Adhesives & Sealants, LLC is a privately-held adhesives and sealant company specializing in epoxy, urethane, solvent-based and water-based adhesives, sealants, and potting compounds used in a wide range of industrial applications. Headquartered in South Bend, Indiana, Royal operates state-of-the-art ISO 9001/ 2008 certified laboratories and manufacturing facilities in Indiana, New Jersey and California. Royal provides high-performance and customized solutions meeting the end-use requirements of its customers through constant innovation. From this demand for the highest quality products, it was no surprise that in March, 1997, Royal acquired the C. Gunther Company, located in Cary, Illinois, a market leading supplier of mirror mastics. These adhesives are used to bond mirrors to a variety of different materials related to both commercial and residential mirror installation. These products are now sold under the Gunther Mirror Mastics brand.
