For best adhesion, bonding surfaces should be smooth, clean and dry. The optimum temperature range for this double-sided tape is 16 to 40 C. If the temperature is lower than 10C, it cannot be firmly stuck to the object because the adhesive will harden. It is recommended to use a heat gun or hair dryer to heat the double-sided tape to best restore the chemical molecules on the tape. Features: 1. The long-term temperature resistance is 132C, and the short-term temperature can reach 208C. 2. Good adhesion, suitable for non-structural fixings of different materials. 3. Waterproof, solvent resistant, high temperature resistant, good adhesion to curved surfaces, can fill irregular surfaces, excellent filling power, unique adhesive suitable for different surfaces. Note : 1. This double-sided tape requires time and pressure to achieve maximum adhesion. You need to press the surface firmly and then peel off the red film. 2. Leave it for 3 days to make it fully bonded. Optimal adhesion will develop over time. Achieve 50% adhesion in 20 minutes, 90% adhesion in 24 hours and 100% adhesion after 72 hours. It is ideal for mounting large and heavy tools, greenhouse covers, teaching materials, posters and picture frames FLEXIBLE AND EXPANDABLE: Simple take off, without glue, without heating, without screwing, without damaging the wall. The foam tape can be extended according to your needs 2-Way Waterproof Tape: High adhesion acrylic foam tape is suitable for most surfaces, including installation at outdoors or in damp locations. Compatible with almost all LED strips including 2835, 3528, 5050 and more Easy to install: - This foam tape is easy to install, just peel off the tape and stick it to the surface of the object. Easy to reposition when not fully compressed, repositioning does not affect bond durability, fast and strong bond when fully compressed VERSATILE TAPE: Multi-purpose tape with comfort foam on both sides provides adhesion to a variety of painted surfaces, including powder coating. Such as automotive LED signs, decorative strips, door sides, body side decorative strips, stainless steel, ABS and PVC door sill panels, wheel lips, nameplates and decorative strips< /p>
