Performance Of Protective Film For Color Steel Sheet
- Sep 21, 2018 -

One.

1. Adhesion performance test: easy to stick to the surface of the object, leaving no residual adhesive: A. with the object bending 90 degrees, not breaking, not falling off; B. after tearing off the film Zburg cable test, leaving no residual adhesive on the surface of the film.


2. load test: 360h25 degree -50 degree withstand /SPCM2 load, peel off after glue trace no residue surface.


3. Ultraviolet aging test: at 50 degrees, 300 W ultraviolet lamp irradiated for 60 hours without cracking, no deformation, no residual surface after tearing.


4. moisture and heat aging test: after 60 degrees +80%=240H, it will not fall off. After stripping, it does not leave any residual glue and does not corrode the surface.

Two. Paste requirements: the surface should be dusty without oil.


Three. Main technical parameters:


1. Viscosity: Medium Viscosity - Substrate: Polyethylene - Thickness: 0.05-0.13mm - Peel Strength (KN/M): 0.06-0.07 - - Tensile Strength: 600-800 - - Fracture Elongation: 150-180 - - Temperature Resistance: Less than or equal to 60 degrees;


2. High viscosity - base material: polyethylene - thickness: 0.05-0.13mm - peel strength (KN / M): 0.08-0.11 - Tensile strength: 600-1000 - elongation at break: 180-200 - temperature resistance: less than or equal to 60 degrees;


3. Viscosity: Ultra High Viscosity - Substrate: Polyethylene - Thickness: 0.05-0.13mm - Peeling Strength (KN/M): 0.22-0.32 - Tensile Strength: 600-1100 - Breaking Elongation: 150-220 - Temperature Resistance: Less than or equal to 60 degrees;
