In each product any 3key on the smoothed HB pencil with 500 grams of force, uniform speed 45 degrees sample Under the surface 1; Scratches are about 6.5mm; 2. On any 3key of each product, smooth the polished 2H pencil with a force of 1000g, and scratch the sample surface uniformly at 45 degrees; the scratches are about 6.5mm, and then Observe the sample, pass the physical property test standard, pass the physical property test standard;
* Butanone resistance test, 3pcs, test sample appearance should be no change, coating layer without dissolution and exfoliation phenomenon, at room temperature, 50% relative humidity, with MEK liquid coating the sample, to add reagents to ensure that the surface lasts 2 minutes Do not dry, remove the test sample after 2 minutes with a dry cloth, and check the appearance of the test sample, physical test standards passed;
* Wear resistance test, 1pcs, other test points> 50 Cycles, RCA friction machine 275g pressure continuous friction 50 times, physical property test standards passed;
* Wear test, 1PCS, other test points> 50 Cycles, with a sand face eraser rubbing machine 1500 grams of pressure continuous friction 50 times, the physical test standards passed. The above data is the thickness of our laboratory's screen printing process, 250 mesh fabric. According to different printing methods such as the transfer process; film thickness, substrate (surface hardness) of different wear parameters slightly different. This ink can be well attached to a variety of materials, such as, ABS + PC, ABS, PC, UV paint, PU paint, metal. It is a solvent-based two-component ink.
