01. How does the thermal insulation coating work?

There are three methods of heat transfer:

  • Conduction is transfer of heat between atoms as they collide within a substance, from hotter part to less one.
  • Convection is the movement of matter due to differences in density that are caused by temperature.
  • Radiation is the transfer of energy by electromagnetic waves, such as visible light and infrared waves.

Neo Chemicals applies the common physics principles of heat transfer (conduction, convection, radiation) to make the effective thermal insulation coating.

  • The coating structure consists of ceramic bubbles reflects up to 90% of the radiation heat.
  • Each ceramic bubble encapsulates air leads to break down the heat transfer process.
  • The dry coating film has low thermal conductivity (k value) leads to slow down the heat transfer process.

02. Requirements for efective thermal insulation solution?

  • Very low thermal conductivity coefficient.
  • Good reflection capability.
  • Durability under all climates, including coastals.
  • Easy application (or installation), does not affect activities inside.
  • Easy maintenance.
  • Non-flammable and non-explosive.
  • Non-hazardous components to the environment and health.

03. How to choose the right insulation coating?

  • Low wet weight of the coating, not higher than 0.78 kg/liter. (wet weight of water = 1kg/liter)
  • Thermal conductivity (k) of the coating is low, it should be below 1 W/m.K.

04. Can white paint be used instead of thermal insulation paint?

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...

05. How to distinguish reflective paint with true insulation paint?

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.

06. Compare thermal insulation solution between insulation coating with conventional solutions


Problem solving methodPrevention: Protect the surface out of heat.Cure: Accept surface heat by absorbing solar radiation completely.
Anti-heat EfficiencyHigh. 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.
ApplicationEasy and fast application, no interruption in production inside.Difficult and complicated, interrupting production inside.
MaintenanceEasily. 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.
