New tesa® 50620 Basic powder coating tape for general applications
(curing temperatures up to 200°C for 30 minutes)
Powder coating is a very demanding application that requires special masking tapes that can withstand high curing temperatures and are tear-resistant enough to be easily removed afterwards. The process is used to create a highly resistant and uniform finish as protection or decoration on metal surfaces.
In the first step, the free-flowing, dry powder is applied to the material electrostatically, so it is literally drawn into the tiniest gaps. In the second step, the coating is typically cured by heat, for example at 200°C.
This causes the powder, which often contains a thermoplastic or thermoset polymer, to melt into a durable finish that is tougher than conventional paint. This exceptional resilience makes powder coating the preferred choice for metal working industries from household appliances to transportation and aerospace industries. In addition, powder coating does not release volatile organic compounds (VOCs).
For the masking tapes used in this extremely demanding process, it is crucial that they produce sharp edges and leave no residue when removed after curing. While paper masking tapes can withstand high temperatures, they have neither the tear resistance nor the tensile strength required for this application.
Therefore, tesa have developed special masking tapes that are very thin, seal tightly, and withstand high temperatures without shrinking or edge lifting. Even after curing, when they are partially covered with the hardened finish, they can be easily removed without tearing or residues leaving behind sharp edges.
