Excellent Weatherability ASA

With the automotive industry increase weatherability requirements to paint-free interior and exterior parts, KUMHO-SUNNY developed excellent Weatherability ASA resin, by using the fourth monomer and compatible distribution technology.

With the automotive industry increase weatherability requirements to paint-free interior and exterior parts, KUMHO-SUNNY developed excellent Weatherability ASA resin, by using the fourth monomer and compatible distribution technology. 

 

 

Characteristics

 

  • Increase weathering resistance by 40% compare with the common ASA 
  • Maintain high performance good long-term usability after aging
  • High Flow

* Test Standard: SAE J2527 (SAE J1960)

After 3500 KJ/m2 irradiation of xenon lamp, ASAXC811-HW still maintains smaller delta E and higher color fastness.

 

 

Long-term Usability Evaluation---Heat Aging

 

* Test Standard: ISO188

After 1000 hours heat aging, ASAXC811-HW mechanical properties has little changed, and still maintains high performance.
