A 4.0 mil. thin polyester backed tape with a rubber adhesive ideal for bonding a wide variety of similar and dissimilar materials such as rubbers, metals, glass, paper, paints and many plastics. The 830 firm rubber based adhesive provides good anchorage to the carrier, giving one piece removal characteristics. 830 adhesive also gives a combination of high shear holding power, good high temperature performance, good solvent resistance and good adhesion to a wide variety of materials. 442W tape includes a film carrier which adds dimensional stability for aid in removal and easier handling during slitting and die-cutting. Initial tape application below 50Â°F is not recommended because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is generally satisfactory.
