Include anti-graffiti property, anti-viscosity, salt fog resistance, adhesive force and photocatalysis effect.
Wherein anti-graffiti property test method uses 00 StandardPractice for of standard ASTM D6578-
Determination of Graffiti Resistance, the standard method principle are that the material that will scribble imposes on coating surface,
By pressing defined cleaning method cleaning scribble surface after a certain period of time, the anti-graffiti property of coating is indicated with rank capable of washing.
Anti- viscosity test method uses GB/T2792-1998 " 180 ° of peeling strength test methods of pressure sensitive adhesive tape ", uses 3M
Single side marking tape as simulation paste, observation film layer whether peel off, whether there is or not obvious loss of gloss, whether there is or not glue residua objects.
Salt fog resistance test is that the good template of film is inclined in salt fog cabinet, observes template after a period of time
Corrosion, sprawling and blistering degree, record occurs corroding or cream time.
Adhesion test method is carried out using X method is drawn, and is measured using 9286-1998 standard of GB/T.
Photocatalysis effect uses decomposing formaldehyde method, and the template for applying and wiping is placed in cabinet, while being filled with concentration is 20mg/
m3Formaldehyde measures concentration of formaldehyde in cabinet after illumination 8h, calculates degradation rate.
