Nano-silica can be added to the coating to improve coating scrub resistance, strength, hardness and so on. Add a small amount of our material nano-silica (VK-SP30T) in coatings, anti-UV coating aging test performance to be reduced from 250h to 600h or more scrub more than 10 times an increased drying time significantly reduced, and the presence of raw materials poor stability of the suspension, thixotropy poor, not high finish was also a very good solution.
