Frequently Asked Questions of Hydrophobic Paint
A white roof is coated with heat-reflective white coating which reflects up to 90% of sunlight. White roofs are much more than just white paint it is an indicator of the ability of a surface to reflect solar heat.
Heat Reflective Paint. There has been a revolution in the paint industry with the advent of heat reflective coating, which improves the insulation properties of buildings in an environmentally friendly manner. Generally, these paints are available in light colors because they can reflect up to 80% of the solar radiation.
Specialist heat reflective paints are also available, but their effect is minimal compared to going from dark to light colour. Heat reflective paint allows more energy from the sunlight to bounce off than usual paint of the same colour. However compared to painting a dark roof with non-heat reflective light colored paint, the effect is only mild.
Heat reflective paint designed to reflect more sunlight and absorb less heat than a standard roof. The usage increases roof temperature and decreases room temperature correspondingly.
In industries where heat is used for process, heat insulation coatings are used for energy saving purpose up to 1800 degrees C. This decreases heat transfer from inside shell to outside and thus lowers fuel consumption, increasing energy savings.
