What Is the Maximum Temperature for Flex Tape?
Flex Tape is made to withstand tough conditions, including high heat. Whether you're using it on outdoor equipment, vehicles, or sun-exposed surfaces, it's important to understand how this super-strong tape performs in elevated temperatures.
Flex Tape Application Temperature Range
Flex Tape is best applied to surface temperatures from 20°F to 120°F. Once fully bonded and cured, it can withstand temperatures from -70°F to 200°F. Flex Tape maintains a strong, waterproof seal under high heat, making it suitable for:
- Hot rooftops
- Direct sun exposure
- Outdoor metal fixtures
- Automotive and RV surfaces
Important Note: Flex Tape is not rated for extreme heat applications, such as exhaust systems or surfaces that exceed 200°F.
Best Flex Tape Uses in Hot Conditions
- Outdoor hoses or pipes exposed to the sun
- Sealing roof joints or flashing
- Temporary repairs on RVs or trailers
- Outdoor gear, storage, or tools
