Pe protectivefilm for marble performance requirements
1. The pe protectivefilm for marble is inert to the surface of the material to be protected.
2. The protective film has good adhesion to the material to be protected. During the material handling and processing, the protective film does not rise and fall off.
3, the protective film has good weather resistance and stability of the holding force. After several days or a long time, the peeling force is not significantly increased, and it is easy to remove. When the film is removed, no residual glue remains on the protected surface, and no shadow is left.
4, low crystal point
Pe protectivefilm for marble requirements
1, suitable viscosity: easy to paste easy to tear.
2, the peeling force is stable: the change over time is small, that is, the smaller the peeling force is, the better.
3, good weather resistance: under the conditions of sun exposure, the use period is up to six months to one year.
4, long storage period: stored in the warehouse for more than one year, no change in quality.
5, no pollution, no corrosion: the adhesive is inert, will not react with the surface of the material to be bonded.
6, mechanical properties: in accordance with user requirements for tensile strength, elastic modulus, elongation and so on.
