Application process

Ensure surface is clean from dust, grease, and loose material. The substrate must be dry and free from frost. Prime surface with Partel ACRAPRIME and allow sufficient time for the primer to dry depending on conditions. This will eliminate dust particles and result in a better bond. Cut the required length for connection, peel the release liner from the tape and with sufficient downward pressure press tape onto the substrate to activate the acrylic adhesive, use Partel HELPING HAND to apply pressure evenly.

Connections joints should be free from tensile strain. Acrylic-based adhesive tape is pressure activated, sufficient pressure is required to ensure a long-lasting bond. A smoother physical substrate will result in optimum adhesion between tape and surface. It is the responsibility of the applicator to check the substrate for the suitability, adhesion tests are recommended in non-standard situations.
