OSI® QUAD MAX® ´s durable, next generation sealant takes toughness to the next level, with a superior combination of adhesion and flexibility for a long-lasting finish. It also takes the guesswork out of color matching with over 300 colors that directly match more than 9,200 finishes offered from leading window, door and siding manufacturers. QUAD MAX’s clear option is a non-cloudy formulation that, unlike traditional silicones and hybrids, remains transparent and resists yellowing from UV exposure.
