Dr. Fixit Heatshield is a heat reducing & ‘Energy Saving’ elastomeric coating composed of acrylic emulsion polymers, microspheres, properly selected & graded inert fillers, light fast & weather durable white pigments, additives & water as medium. It is used as a heat insulating coating on building rooftops & exterior walls because it helps in reducing power consumption substantially by reducing the load on air-conditioners & keeps the interiors cool with additional function of waterproofing.

Description

Dr. Fixit Heatshield is a heat reducing & ‘Energy Saving’ elastomeric coating composed of acrylic emulsion polymers, microspheres, properly selected & graded inert fillers, light fast & weather durable white pigments, additives & water as medium. It is used as a heat insulating coating on building rooftops & exterior walls because it helps in reducing power consumption substantially by reducing the load on air-conditioners & keeps the interiors cool with additional function of waterproofing.


About the product
Dr. Fixit Heatshield contains advanced material of ‘Hollow Micro spheres based on Borosilicate Glass as micro bubbles’ having remarkable ‘Heat Insulation’ property. The unique spherical shape of the glass bubble produces stable voids which results in low thermal conductivity and a low dielectric constant. When applied on substrate, the hollow micro spheres form a closely packed structure like ‘Air Space’ within the dry film layer that serves as insulation medium to resist heat transfer. Dr. Fixit Heatshield has thus the ability to slow down heat transfer remarkably and keep interiors of externally coated surface of a building cooler by re-radiating most of the solar heat back into the atmosphere.

Specification: Conforms to AST M E-903

Areas of Application
1. Terraces and rooftops of buildings - cementitious, asbestos & metal surfaces
2. Industrial & godown shades with GI or asbestos roofs
3. Exterior walls of buildings
4. Cold storages, computer server rooms, electrical control panel rooms, etc
5. Metal & concrete storage tanks for water, chemicals and fuel in petrochemical industry

Features & Benefits
1. Heat Insulation - Reduces the conductivity of heat from exterior to interior, thus lowers the temperature.
2. Solar Reflectance - 83.8% solar reflectance ( AST M E-903 ), re-radiated heat back to atmosphere
3. UV and IR resistant - Resistance to UV & IR emission, protects coating from damage and reduces heat conductivity.
4. Microbial resistant – Resistance to algae and fungus growth results into lesser maintenance.
5. Non-Toxic water based system - Eco friendly
6. Energy Saving - Reduction in electrical consumption for air-conditioners, saves energy cost.

Method of Application
Surface Preparation: on Cementitious Surfaces
1. Surface to be applied upon must be free from dust, loose material, paint, oil, or any other material which may impair adhesion
2. Mechanical means such as wire brushing & shot blasting can be used. Finally vacuum cleaning of all loose solids and liquids can be done if required
3. All surface cracks up to 5 mm width should be filled up with Dr. Fixit Crack X or Dr. Fixit Unifiller.
4. Cracks more than 5 mm and all separation gaps should be filled up with Dr. Fixit Pidicrete UR P or Dr. Fixit Unibond SBR modified mortar or as specified.

1 Priming
a. All new cement-sand renderings & concrete surfaces should be allowed to age for 6 to 8 weeks before surface coating
b. Attain SS D condition before priming
c. Prime with Dr. Fixit Primeseal (2 part primer : 1 part water)
d. Apply with brush or roller.

2 Application
a. Apply 3 coats of Dr. Fixit Heatshield without any dilution by brush or roller at an interval of 2-3 hours.
b. Allow the coated surface to air cure fully for 7 days.

Surface Preparation: on Metal Surfaces
a. Metal surface should be cleaned to remove existing paint, rust by appropriate mechanical or chemical means.
b. New surface should be de-greased and cleaned well

1. Priming
a.Prime the metal surface with suitable anti-corrosive primer.
b.Priming is not required for new GI sheets.

2. Application
a. Apply 3 coats of Dr. Fixit Heatshield without any dilution by brush or roller at an interval of 2 hours.
b. Allow the coated surface to air cure fully for 7 days.

Precautions & Limitations
1. Do not dilute.
2. A lways to be kept as final coat. i.e. No overcoating on Dr. Fixit Heatshield.

Coverage
3m2 per ltr per coat.
*Coverage may vary depending upon the texture and porosity of the surface
