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
