Adhesive Options for This EPDM Rubber Profile

3M™ BONDED TAPE SYSTEM 
The 3M Bonded Tape System enables you to achieve the ultimate bond to the rubber and the ultimate bond to the substrate. This tape option creates a moisture barrier and air-
tight seal. With the highest peel-and-sheer resistance, the 3M Bonded Tape System can be used under high loads of stress and force. It has low initial tack for easy repositioning 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.


3M™ Heat-Activated Acrylic Foam and Acrylic Plus Tape

STANDARD PRESSURE SENSITIVE ADHESIVE
The Standard Pressure-Sensitive Adhesive option for your seal is an acrylic-based adhesive. 
It works best when used to hold the seal in place while installing in a static application or when it’s compressed between two stationary objects. It may be used in some light-duty dynamic applications against a variety of substrates. It is rated for good heat performance between -20°F to 158°F. Please note: During installation, ambient temperature must be above 60°F.
