ROUGH SUBSTRATES

FOR COATINGS

20RCMA Annual Meeting – February 27, 2017

BACKGROUND

• Round robin – confirmed reproducibility and repeatability of solar reflectance testing

• Specification to implement procedure−Prepared vs. commercially-available substrate

−Thermal emittance testing

−Weathering/field exposure

RCMA Annual Meeting – February 27, 2017 21

SUBSTRATE

• Discussed commercial substrate −Potential to reduce error in preparation

−Ease of preparation

• M&I confirmed use of prepared substrate at December 2016 meeting

−Round Robin confirmed reproducibility and repeatability

−No study using commercial product as substrate

RCMA Annual Meeting – February 27, 2017 22

THERMAL EMITTANCE

TESTING

• Applicability of slide method discussed−Potential damage to equipment

• Devices & Services completed preliminary testing

−0.002 to 0.006 higher – slide method

−Surface temperature effect

−Surface roughness effect (0.018 displacement)

• Effects minimal and tend to offset one another

RCMA Annual Meeting – February 27, 2017 23

WEATHERING

• No weathering of rough specimens completed −Durability of specimens

• Working group discussed solutions (February)−Weather specimens

−Simulate weathering

• Working group confirmed need for 3-year aging

RCMA Annual Meeting – February 27, 2017 26

• Timeline – begin weathering by end of 2017

• Identify coatings to weather

• Determine level of significance

• RCMA participation−Study design

−Volunteers
