One of the main reasons why this product is known and trusted for use in so many industries is because of its broad temperature compatibility. When put to the test, this tape continues to work effectively in some of the most demanding work conditions. The pressure sensitive silicone adhesive is ideal for high temperatures up to 400°F (204°C) with clean removal during high-temperature masking operations. This product can also be used in temperatures as low as -60°F (-50°C). This represents superior heat resistance when compared with acrylic adhesives.
