COOL COAT ELASTOMERIC PAINT REDUCES HEAT BUILDUP ON WALL & ROOFS
Rainguard COOL COAT Ready-to-Use White is a premium quality, heat reflective paint and thermal barrier high build, 100% acrylic water-based white color elastomeric waterproofing coating with ceramic sphere technology to reflect infrared radiation that provides insulating benefits in both the summer and winter. Over 200% dynamic elongation and recovery strength ensures that the coating will move and flex with the thermal changes of the masonry surface to help prevent rupturing or cracking.
COOL COAT is vapor permeable yet resists the effects of wind driven rain. It restores and beautifies damaged masonry surfaces and unifies color and texture on new surfaces.
Comes standard in white color with a Satin Gloss Finish. COOL COAT also comes in a Clear Satin Gloss or one of 3 different tint bases for custom tinting. Use on new or existing surfaces including block, brick, stucco, cement, concrete, wood, metal and EFIS. COOL COAT is quick drying with excellent adhesion and hide.
As a Thermal Paint, Works Like a Liquid Pane Of Thermal Glass. Offering Both Heat Reduction And Cold Protection Paint Film. To cool in the summer apply on exterior walls or roofs to keep heat out and in the winter to keep heat from escaping outside apply to interior walls. Cool Coat is an effective insulator by reflecting infrared radiation from whatever surface it is applied to since most heat is transferred by infrared radiation.
Primer:
For painting bare ferrous steel, galvanized steel, aluminum first prime with a corrosion resistant metal primer such as Plugger Universal Primer. Plugger Universal Primer can also be used on porous concrete, brick, stucco and previously painted surfaces when a primer is needed prior to application of Cool Coat Thermal Barrier Coating.
For smooth, slick, non-porous surfaces such as vinyl, plastic, polycarbonate, fiberglass, glass recommend bonding primer like Extreme Bond Primer.

The solar reflectance, thermal emittance and SRI value of a wall or roof surface are important surface properties affecting temperature, which, in turn, drives the heat flow through the wall or roof. Cool Coat test results below demonstrate its effectiveness.
OPTICAL PROPERTIES
| TESTED | SOLAR REFLECTANCE AT AIR MASS 1.5 | THERMAL EMMITANCE AT 300K |
|---|---|---|
| Cool Coat | .812 | .875 |
| Uncoated Sample | .653 | .040 |
SOLAR REFLECTANCE INDEX (SRI)
| CONVECTION COEFFICIENT | COOL COAT | UNCOATED SAMPLE |
|---|---|---|
| Low, 5 W/m (2) K | 101 | 6 |
| Medium 12 W/m 92 K | 101 | 45 |
| High, 30 Wm (2) K | 101 | 63 |
Solar reflectance determines the fraction of the solar radiation incident from all directions that is diffusely reflected by the surface. The higher the solar reflective value the more efficient the product is in reflecting sunlight and heat away from the building and reducing roof and wall temperature.
Thermal emittance describes how well the surface radiates energy away from itself as compared with a blackbody operating at the same temperature. In warm and sunny climates highly emissive roof and wall products can help reduce the cooling load on the building by releasing the remaining heat absorbed from the sun Scientists use a number between 0 and 1, or 0% and 100%, to express emittance (the higher the number the more effective the coating).
Solar Reflective Index (SRI) SRI is calculated by using the values of solar reflectance, thermal emittance and a medium wind coefficient. The higher the SRI value, the lower its surface temperature and consequently, the heat gain into the building
