RD-Sunguard
Technical sheetHigh performance solar reflective coating with exceptional properties. Cool Roof system.
Helps our planet by reducing surface temperatures and urban heat island effects
• SRI index ≥ 110 – Solar Reflectance Index - ASTM E 1980
• TSR ≥ 88 % – Total Solar Reflectance - EN 14500 part B and EN 410
• High degree of whiteness and UV resistance
• Maintains its high reflectance value over time
• Excellent dirt pick-up resistance and self-cleaning properties
• Excellent resistance to weathering
Much more powerful than any ordinary white paint!
RD Coatings has developed a new type of universal coating based on very innovative chemistry and capable of maintaining the most important properties required for cool roof coatings. RD-Sunguard ensures long-lasting performances, whether it is energy savings, better thermal comfort or lower heat effect.
BENEFITS:
1. Lower the energy bill of buildings as less energy is used to cool the inside
2. Increase the productivity of solar panels on roofs
3. Reduce Urban Heat Island Effect (UHI) and lower the Carbon Footprint
4. Better thermal comfort by decreasing by several degrees the temperature inside buildings

Description of the product
USE:
High performance solar reflective coating - Cool Roof system
FEATURES:
Single component water-based solar reflective coating based on new generation of resins enabling the coating to boost its solar reflective properties.
Thanks a high solar reflective index (SRI) over 110, to its special pigmentation, very high UV and excellent dirt pick-up resistance, and self-cleaning properties, RD-Sunguard helps to keep and maintain the surface white and clean to ensure maximum solar and heat reflection over time.
RD-Sunguard is water-based, easy to handle, safe and has no fire risks. It is a fast-drying coating system that greatly reduces downtime during installation and increases on-site labour productivity.
Virtually odour free, it does not affect neighbouring occupants and can therefore be used in occupied buildings.
RD-Sunguard ensures long-lasting performances, whether it is energy savings, better thermal comfort or lower heat effect.
SUBSTRATES:
RD-Sunguard can be used on most kind of surfaces providing first the application of an adequate primer coat (see table with systems)

In case of problematic surfaces like highly corroded, leaking, peeling … refurbish first the surface as described in our Solution pages or contact your RD representative for advice.
Indicated consumption is theoretical and does not consider potential losses during application.
It can also be influenced by the porosity of the substrate.
