One of the best ways to choose a car masking tape is to consider its technical specifications, learning to read them properly and understand exactly what they refer to. In this article, we give you a little help.
The best car masking tapes guarantee a long series of technical features that improve their performance. It’s not just a matter of numbers: each feature is associated with a specific quality of the tape, and reflects on the final result when painting a car. When you choose a car masking tape, you should be able to read its technical sheet in order to compare different products and buy the best one: here is a brief guide to the most important features you have to consider.
- Dimensional features: the width of car masking tape is important, as different tapes are required for different uses. Larger masking tapes are perfect to support masking films and paper when covering wide areas of the car, while the narrowest tapes can be used directly on small components or surfaces for a high precision masking. Another important feature to consider is the thickness of the tape, which is the distance between the backing and the adhesive surface.
- Tensile strength: tensile strength indicates the force required to break the tape or, in other words, the maximum load it can withstand. A tape with a high value of this parameter avoid breaks and rips when applied and removed.
- Elongation capability: strictly related to tensile strength, elongation is the ability of the tape to stretch when force is applied. Elongation is important when applying the tape on the car, stretching it to fit irregular surfaces: in this particular case, we talk about conformability.
- Temperature resistance: this is one of the most important features of a car masking tape. Car painting requires one or more drying cycles, during which the car is exposed to high temperatures: in these phases, the tape has to keep its hold steadily and prevent the paint from bleeding, or the adhesive from sticking too much to the paint itself. Good car masking tapes should withstand a temperature above 80° to perform properly.
- Shear adhesion: this parameter indicates the ability of a car masking tape to bear the weight of an object prior to come loose from a vertical plane. In car painting, you have to consider shear adhesion when choosing a tape to apply masking films or paper: in this case, shear adhesion indicates the time the tape can keep the film in place, before slipping downward.
- Water and solvent resistance: when you are using water-based paints, water resistance is important as it refers to the capability of the tape to resist water, keeping unaltered the features of its adhesive. Strictly related to water resistance we find solvent resistance, which indicates the ability of the tape to resist the attack of organic solvents.
