Jiffy Seal® Ice & Water Guard HT BUTYL

For Very High Temperature, Highly Conductive Roofs and High Altitude Applications. Protects Your Roofs from Ice Dams and Wind Driven Rain.  A proprietary RECYCLED butyl Adhesive. Our BH formula contains the Protecto FM™ Technology, which promotes excellent adhesion to the substrate at the molecular level and provides improved initial tack and facilitates easier application at low temperatures (40°F ). The butyl component contains the same 100% recycled post-consumer material base as our Butyl adhesive. Butyl adhesive shares the same high temperature limitation as our rubberized asphalt adhesive (300°F) as well as the same chemical compatibility limitations.
