*3M™ Adhesive 100 is a firm acrylic pressure sensitive adhesive system. It features high ultimate bond strength, very good high temperature
and solvent resistance and very high shear holding power. Bond strength increases substantially with natural aging.
3M™ Adhesive 740 is a medium-firm rubber-resin pressure sensitive adhesive system. It features good holding power and adhesion to a
wide variety of surfaces including many low surface energy plastics such as polyethylene and polypropylene.
