Adhesion performance test: It adheres to the surface of objects easily, and does not leave residual glue. The steel plate will not break or fall off when bent 90 degrees. When removing it from the film Pittsburgh cable, there will be no residual glue left on the surface of the film. Load test: It can bear a /SPCM2 load for 360 hours at 25 degrees to 50 degrees, and after being taken off, there will be no residual glue left on the surface. UV resistance test: After being subjected to irradiation of a 300W UV lamp for 60 hours at 50 degrees, it does not crack, deform, and no residual glue is left on the surface. Dampness and heat resistance test: At 60 degrees 80%=240H, it has no residual glue on the surface and does not corrode the surface after being taken off. High temperature resistant test: At 200 degrees, it will not fall off after three minutes, with no residual glue or corrosion on the surface after being taken off.
