There are three methods of heat transfer:
Neo Chemicals applies the common physics principles of heat transfer (conduction, convection, radiation) to make the effective thermal insulation coating.
We need to distinguish the concept of true thermal insulation paint with reflective paint, as described above, true thermal insulation paint uses insulation principles: dissipating heat or cold temperature, preventing heat absorbtion, and slowdown heat transfer. The white paint has only one function of reflecting the sun's rays (until the paint gets dirty), which leads to a decrease of heat transfer to the inside. White paint can not replace thermal insulation paint. Thermal insulation paint creates the temperature difference between the two surfaces, can be tinted with any color, can be applied inside or outside of the surface. Reflective paint can only be applied outside and "paint film always clean & white", Reflective paint can only be used on corrugated iron roof, It can not be applied for thermal insulation applications such as insulation pipes, hot liquid tanks, boilers, hot oil tanks, steam pipes...
Insulation paint is lighter than water, weight from 0.60 to 0.80 kg per liter, 17 liters pail weighs about 10-15 kg. Reflective paint is much heavier than water, weight from 1.20 to 1.40 kg per liter, 17 liters pail weighs about 20-24 kg. In fact, to choose a true thermal insulation paint, the lighter weight the better thermal insultion paint.
|THERMAL INSULATION COATING||CONVENTIONAL SOLUTIONS|
|Problem solving method||Prevention: Protect the surface out of heat.||Cure: Accept surface heat by absorbing solar radiation completely.|
|Anti-heat Efficiency||High. Thanks to preventing solar energy from absorbing or transferring into the inside.||Low. Ex: insulation sheet installed under the roof, the roof absorbed heat, so it still transfers inside.|
|Application||Easy and fast application, no interruption in production inside.||Difficult and complicated, interrupting production inside.|
|Maintenance||Easily. Roof is protected by the coating so it does not rust or leak. Easily detect leaks when it rains.||Difficult, not detect leaks when it rains, the roof is easy get rust and leakage due to polution environment.|
|Economic benefits, added values.||Protect the roof from rust, corrosion, increase the life of the roof for more than 20 years.|
