3M Scotch-Weld Plastic & Rubber Instant Adhesive PR100 is formulated for exceptional performance on difficult-to-bond substrates, such as EPDM, polypropylene, and polyethylene, with the use of an appropriate primer. When applied, this adhesive has a short handling time of 20 seconds, with a full cure in 24 hours; once cured, it creates a strong, durable, and lasting bond, with high overlap shear strength. During use, 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR100's flexible container allows for two application methods, either pinch for a precise drop or squeeze for a steady bead.
