XENON TEST

Task:

In cooperation with the renowned „eph-Institut“ located in Dresden, Germany – Resysta carried out an „artificial weathering test of selected materials“. The Xenon test was chosen as test procedure.

Test Performance:

Artificial weathering was carried out for 2000 h (after 650 MJ/m2 irradiation) with a Xenon tester CI 3000 (test device KL 31) according to DIN EN 11341. Artificial weathering was conducted at the following test conditions:

  • 55°C black standard temperature
  • 50% relative humidity
  • Radiation intensity 0.5 W (m2 x nm) at 340 nm
  • Weathering cycle: spray cycle 18 min, drying phase 102 min

A factor of 15-25 can be applied to this 2000 h test. Assuming factor 20 and an average of 7 sunshine hours per day (Central Europe) this corresponds to a weathering period of 15 years.

The following assessments were carried out to characterize the weathering resistance:

  • visual evaluation of color change by means of gray scale according to DIN EN 20105-A02
  • visual evaluation after 500 h, 1000 h, 1500 h and 2000 h.

 

Test Material:

eph-Institut“ was provided with 15 material samples with two test specimen each. One specimen of each version was subject to the weathering test.

Winner in the long-term test

CONCLUSION:
Resysta combines all the materials tested
natural look and feel are the most convincing with longevity.

SCRATCH TEST

Test Condition
Substrate Resysta Decking
Conditioning 7 days at room temperature
Clear Sealer coat 1: Resysta UV Sealer RSI30
Clear Sealer coat 2: Resysta 2K Sealer RFS10

Final Result

All three tests show that the RSI30 UV coated Sealer substructure has much higher wear and scratch resistance compared to the RFS10 2K Sealer.
