    Why OSI and what is it?

    OSI® is a trusted brand because it was born on the jobsite. A group of tradesman created OSI, seeking better performance from the products they were using every day. Their experience and persistence helped build one of the toughest portfolios of construction sealants, adhesives, foams and tapes available in the industry — products that stand-up to the elements and provide long-lasting protection.
