Product Specification

Sunsheetal

SunsheetalÂ® is based on polyurethane-acrylic blended elastomeric aqueous polymers. It is a high thermal emittance ceramic coating useful in the world of industrial and commercial buildings, as a roof coating system that has the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, thereby reducing heat transfer to the building.

SunsheetalÂ® is defined as a cool roof coating by virtue of its ability to radiate absorbed, or non-reflected solar energy. Solar heat incident on a roof is dissipated by means of three physical phenomena namely

A fraction of the absorbed heat is conducted to the ground and surrounding buildings
A fraction is dissipated by convection to air leading to higher air temperatures
A fraction is radiated to the sky.

As such one has no control over the first two phenomena but the third one, that is, the amount of heat radiated can be maximized by SunsheetalÂ® roof/ wall coatings that inherently possess high emittance values.

Use of SunsheetalÂ® is particularly useful where the terrace covers an air conditioned space. A higher roof temperature necessarily leads to a higher load on the air-conditioning plant a reduction in roof temperature will result in lower roof temperature with consequent savings in power consumption.

Recommended use

Concrete, Plaster & Asbestos Cement Sheet
Galvanized Tin Sheet
Primed Metal

Advantages

Ready to use single pack system.
Repels heat energy & control heat transfer.
Reduces air-conditioning running cost.
The coating acts as a shield and protects the surface from heat and water.
Its film is water resistant and does not support growth of fungus and algae.
Does not crack due to wide temperature fluctuation.
Cleans up with soap and water.

Special Features

SunsheetalÂ® enhances durability of the roof and reduces both building cooling loads and the urban heat island effect.
SunsheetalÂ® is also an effective alternative to bulk attic insulations under roofs in humid tropical climates. Bulk insulation can be entirely replaced by SunsheetalÂ® roof coatings that both reflect solar radiation and provide emission to the sky.
SunsheetalÂ® has excellent abrasion and water resistance it is also resistant to fungal growth
SunsheetalÂ® is recommended for reduction in the carbon foot print of a building as it reduces fuel consumption of the air-conditioning plant.
In general the roof temperature is in the range of 60^oC to 80^oC in summer and this can be substantially reduced by coating the roof with SunsheetalÂ® , typically various types of roofs will show reduction ( after coating ) of surface temperature as indicated below
RCC terraces: 10^oC to 12^oC
Asbestos cement sheets: 12^oC to 15^oC
GI or powder coated sheets: Up to 20^oC

The above figures are indicative and will vary according to ambient atmospheric conditions such as wind velocity etc.

Direction for use

Application areas to be cleaned with a hard brush to remove all dust, weak paint, fungus etc. Cleaned area to be washed with water.
The surface should be moist before application.
Stir the paint thoroughly before each use.
Apply first coat with brush on the cleaned & washed surface.
Apply second coat after a gap of minimum one hour.
Ensure that the coated area does not come in contact with water for at least one hour.
After completion of full coating, it should be allowed to cure for 24 hours

Coverage: One ltr. SunsheetalÂ® covers 40 sq.ft. area in double coat for smooth surface.

Colour: Off-white base. Tintable to any light shade, using appropriate strainer.
