Intertape PG21A is a beige, high-temperature fine crepe paper masking tape with a pressure-sensitive natural rubber adhesive — IPG's premium masking tape for automotive, truck, bus and marine paint masking. It is designed for clean removal from a variety of surfaces after oven exposure up to 325°F (163°C) for 30 minutes, delivering 29 oz/in adhesion to steel and 26 lb/in tensile strength from a 7.2 mil backing. The smooth, high-strength crepe conforms to irregular surfaces, corners cleanly, resists paint flaking and leaves a clean, well-defined paint line, and it performs well in wet strip applications. Available in beige, 12mm, 18mm, 24mm and 48mm x 54.8 m (60 yd) rolls, with no liner.
