High temperature resistance is one of the key features of automotive masking tape and other masking solutions for the car refinishing sector. In this article, we deepen a topic that sometimes arises confusion in the field: what temperatures is a masking tape required to withstand during an average painting procedure? How long?
To answer the question, we have to go through the main steps of the painting procedure performed in body shops and car repair centers. Usually, masking tape is applied on the vehicles just once, in combination with masking paper or film, and has to stay in place and maintain its features throughout the whole process. To do so, it has to undergo several drying cycles without losing its adhesive power or leaving sticky traces on the underlying surface.
In the average car painting procedure, drying cycles include:
To gain particular effects, such as pearlescent shades, an additional layer of basecoat is spread before clearcoat’s application. This layer usually dries at 50°C for 15 minutes*.
As it is clear from the data, a good masking tape for automotive refinishing has to withstand a maximum of 90°C for twenty minutes or 110°C for two minutes. Obviously, that’s not all to evaluate the high temperature requirements for a quality tape: we have to consider the exposure time to lower temperatures, too. A good tape has to resist an exposure of 60-70°C for about one hour and a half, or a bit longer if you are using double basecoat.
PPM Industries masking tape 3010 is designed to withstand 110°C for half an hour, 90°C for one hour and lower temperatures for even longer exposure times, so to offer a significant margin to the average requirements of a professional body shop.
