Double-sided tapes

Description
A thin polymer or paper strip with pressure-sensitive Adhesive on both the upper and lower surfaces. In the rolls, a liner (also called backing or release paper) keeps the adhesive from sticking to itself. Double sided tapes are commonly used because they immediately adhere one surface to another, without any dry time. Companies state the tape provides continuous permanent adhesion that is vibration and corrosion resistant while spreading the stress load across the entire length of the joint. The thin bond produces a smooth appearance without the need for mechanical fasteners.
he following table gives several examples:
