BT 3M D-shaped rubber seal diagram3M™ BONDED TAPE SYSTEM 
The BT option for your self-adhesive rubber seal provides the ultimate bond to the rubber and the ultimate bond to the substrate. It creates a moisture barrier and air-tight seal. With the highest peel and shear resistance, it can be used under high loads of stress and force. It has low initial tack for easy re-positioning during installation and needs 72 hours of cure time to come to full bond strength. It is rated for good heat performance between -20°F to 158°F.
