Notes

  • This performance might vary according to different dimension of product.

  • Multi-layer coating is a combination of different type of coatings, and its color,thickness and working temperature might varies from different combinations.

  • PCT test conditions: 121 celcius degrees, 100% humidity,2atms HAST test condition:132 celcius dergees, 95% humidity,2.7atms(mainly for evaluation of material weight loss)

  • HAST (Highly Accelerated Stress Test) condition: 132 celcius degrees, 95% humidity,2.7atms(mainly for evaluation of material weight loss)
