In August 2013 R & D center had developed saturated polyester resin baked paint by many experiments, which has good scratch resistance and excellent alcohol resistance

The old air compressor was unable to meet work needed in September 2013. R & D center bought a new air compressor through the approval of the leadership. The compressor has high power and a large gas tank. It can fully meet the needs of everyday work and make the experiment work to finish more smoothly.
