Heat-reflective Cool Roof Coating

Heat-reflective Cool Roof Coating for Exterior Walls — Solar Reflection & Energy-Saving Protection

Heat-reflective Cool Roof Coating is produced from specifically modified acrylic emulsion base material, blended with rutile titanium dioxide, hollow glass microspheres and ceramic micropowder. The composite formula is presented with infrared rays and thermal visible light, which may reduce the wall thermal conductivity and interior temperature by 3~8°C in non-air-conditioned spaces. The product is steady in external weather resistance, easy in on-site construction, 20kg standard drum packing, and customised colour and packaging options for individual project demands.

What Sets This Coating Apart from Standard Exterior Paint

Traditional paints for outside walls absorb most of the solar radiation and are not efficient in blocking outdoor heat. Heat-reflective Cool Roof Coating is heat reflecting, with various operating principle and material matching design.

The multilayer thermal barrier was constructed on the wall surface with hollow glass microspheres, ceramic micropowder and rutile titanium dioxide. It reflects solar radiation on the wall surface to stop heat penetration fundamentally rather than inhibit interior heat transmission . This will reduce the temperature of the wall surface and the air conditioning load of the building, therefore reducing the long-term energy consumption for the building’s operation.

How the Thermal Reflection System Works

Three methods are used for cooling and heat insulation in synchronisation:

High Solar Reflectance - Infrared reflecting pigments and rutile titanium dioxide reflect solar radiation, keeping total solar reflectance (TSR) above 80%.

Infrared Thermal Emittance - The coating emits absorbed heat into the air, thermal emittance of 0.85 or more. Solar Reflectance Index (SRI) over 100 for long term heat dissipation.

Hollow Microsphere Insulation - Heat conduction is insulated by internal hollow glass microspheres, which slow thermal transfer through walls at high temperatures.

Key Performance Properties

Water, Alkali & Scrub Resistance – Cured film is not affected by long term moisture and chemical degradation. Will not peel or crack with frequent outdoor usage.

Dirt Resistance Surface structure prevents dirt from sticking. Self-cleaning is normal with rain, preserving 85-90% of original solar reflectance over time.

UV & Weather Stability — Modified acrylic emulsion foundation resists UV ageing and is suitable for long-term outdoor exposure in hot, humid regions.

Crack Bridging – Good elasticity reacts to thermal expansion and contraction of substrate, bridging tiny cracks from temperature fluctuations.

Frequently Asked Questions

Q1: How it cools and saves energy?

A1: The composite formula may reflect infrared and thermal visible light, block solar heat and reduce the thermal conductivity of walls. Reduces energy usage and lowers the temperature within the building by 3-8C in un-airconditioned buildings.

Q2: Is it suitable for hot climates?

A2: Yes. It is designed for external use under strong sun radiation, significantly decreasing the inside temperature in hot climate zones.

Q3: What effect does dirt have on cooling performance?

A3. No. Dirt resistance + rainwater self-cleaning preserves 85–90% of original solar reflectance during service life.

Q4: Can it be used on existing exterior walls and coatings?

A4: Yes for new constructions and renovations. Yellowing and loss of reflectivity can be avoided by using a stain blocking primer on bitumen- or oil-stained substrates.

Q5: What construction equipment is suitable?

A5: Brush, roller & spray. For big commercial and industrial applications, high pressure airless sprayers are suggested for consistent film thickness.
