AT163 is a high quality polythene extruded Silver gloss cloth tape coated with a thermosetting, pressure sensitive solvent free rubber – resin adhesive which results in excellent heat resistance, strength and high adhesion. This duct tape has a thermosetting adhesive which make it useful as a temperature indicator as thermosetting occurs at temperature above +110°C. Below this temperature no residue is left*. AT163 has excellent resistance to both water and salt water. This combined with its good abrasion resistance makes the tape an ideal choice for off-shore marine applications. Extremely flexible and will conform to bends and contours. Used for sealing joints in rigid, air duct sealing used throughout the heating and ventilating industry and for joining and sealing lengths of flexible ducting and for joining smooth polystyrene insulation materials, polythene sheeting, joints and reinforcing eyelets. Protection against abrasion in inflatable polythene buildings. * We would always recommend that users should satisfy themselves that the product is suitable for a particular application prior to use.
