Thermacool 0.3M

  • (Customer Reviews)

Thermacool 0.3M Coating is a two-pack, acrylic-PU, heat reflective top-coat. It can be applied on fresh or coated metal surfaces viz. mild steel, galvanized sheets, coloured and coated metal sheets etc.
Thermacool 0.3M Coating is a premium quality high heat-reflective product designed and developed by IIT-Bombay. It is nano-tech based and modified with specially designed filler powder. Thermacool 0.3M Coating has excellent toughness and durability in extreme climatic conditions.

  • Thermacool 0.3M Coating has a Solar Reflectance Index (SRI) of 95; approved by CEPT University as per ASTM method.
  • Thermacool 0.3M Coating provides a robust and long lasting barrier, which increases the service life of the substrate.
  • No rusting, film delamination and blistering observed in Condensation Test, Salt Spray test and Alkali Resistance Test. Tested by Corrosion Science & Engineering Division, Department of Metallurgical Engineering & Material Science, Indian Institute of Technology, Powai, Mumbai.

Thermacool 0.3M Coating can be applied on uncoated or coated metal surfaces.

In case the coating has deteriorated, then the metal substrate has to be thoroughly cleaned and the coating removed. The metal substrate should be made free of peeling paint, mildew, oil, dust, dirt, loose rust or other contamination. High-pressure water-jetting can be used for this purpose. Wire hand-brush, power wire-disc or grinder can be used wherever necessary. Solvent can be used to remove oils and grease patches.

For coated surfaces that are perfectly intact and without rusting, thorough water jet washing and drying is sufficient.

The substrate has to be completely dry before painting.

Note: Application of coating should not be done immediately after a rain, during foggy weather or when rain is predicted.

Priming of Metal Substrate

If the metal surface is perfectly intact, then priming is not required. Thermacool 0.3M Coating can be directly applied over the coated metal after thorough removal of dirt, dust etc. as mentioned in surface preparation.

In case of bare metal/coated metal surface has deteriorated, then substrate has to be prepared and primed, as mentioned in Thermacool STP Primer section.

Thermacool 0.3M Coating is a 2-pack coating system; base and hardener has to be mixed in 4:1 ratio.

Two coats of Thermacool 0.3M Coating has to be applied over the surface prepared dry metal substrate.

Thermacool 0.3M Coating can be applied by brush, roller or airless spray.

  • Thermacool 0.3M Coating : 2 pack Acrylic-PU topcoat.
  • Mixing Ratio - Base:Hardener :: 4:1.
  • Recommended DFT - 2 coats of 50-60 microns per coat i.e. total 100-120 microns.
  • Recommended no. of coats – 2 coats.
  • Re-coatability – Minimum 3-4 hrs before applying the second coat.

Note: Each coat shall be applied uniformly over the entire surface. Skips, runs, sags and drips shall be avoided. Each coat shall be free from pinholes, blisters and holidays. Contamination of painted surfaces between coats shall be avoided.

Base (Part A): Sealed metal drum of 20 litres. Also available in 4 litres pack.

Hardener (Part B): Sealed metal drum of 5 litres. Also available in 1 litre pack.
