For best adhesion, the adhesive surface should be smooth, clean and dry. The best application temperature range for this double-sided tape is 16-40C. If the temperature is lower than 10, it cannot be firmly attached to the object because the adhesives harden. It is recommended to heat the adhesive tapedouble-sided using a hot air gun or hair dryer so that the chemical molecules present on the adhesive tape can recover in an optimal state. The 3M 4611 VHB double-sided tape is made of acrylic foam as the base material and is coated with an acrylic glue. Features: 1. Long-term temperature resistance is 132, short-term up to 208. 2. Good adhesion, can be applied on non-structural fixings made of different materials. 3. Waterproof, solvent resistant, high temperature resistance, 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 must press firmly on the surface and then remove the red film. 2. Leave it for 3 days to be fully adhesive. The best adhesion occurs over time. It achieves 50 percent adhesion in 20 minutes, 90 percent adhesion in 24 hrs and 100 percent adhesion after 72 hrs SUPER STRONG ADHESIVE TAPE:Tapedouble-sided mounting bracket, length 3 m, width 2 cm, thickness: 2 mm. it is ideal for mounting large and heavy tools, greenhouse covers, teaching materials, posters and picture frames FLEXIBLE AND EXPANDABLE: Simple peel off, no gluing, no heating, no screwing and no wall damage. The foam tape can be extended according to your needs TWO-WAY WATERPROOF TAPE: High adhesion acrylic foam tape suitable for most surfaces, including installation outdoors or in damp locations. suitable for almost all LED strip lights including 2835, 3528,5050 and more Easy Installation: - This foam tape is easy to install, just peel off the tape and stick it to the surface of the object. And it is easy to reposition when not fully compressed and repositioning will not influenceadhesion durability, it bonds quickly and securely when fully compressed Versatile Tape: Versatile tape with comfort foam on both sides provides adhesion to a variety of painted surfaces, including powder coats. Such as LED plate, moldings, door edge, body side moldings, panelsstainless steel, ABS and PVC underbody, wheel lip, nameplate and decoration bar for automobiles
