MetalTec TC can easily be applied to joints, pipes,elbows or connectors, valves flanges that are generally difficult to insulate with traditional insulation methods. It can be replaced and maintained easily if technical or maintenance intervention requires dismantling. Here on the port, this crude oil pipes are able to encapsulate energy and avoid to install heating system. Huge energy savings

  • - instruction to use MetalTec TC


      Mix the contents of the can with an electric mixing paddle at max 300 rpm for 3 to 5 minutes, making sure to thoroughly mix the solids from the container's top.


      Minimum curing temperature 15°C, maximum hot spray application temperature 240°C. The coating will not cure below 15°C. Before applying to a substrate where the temperature exceeds 80°C, please contact your distributor.


      Apply MetalTec-TC to a clean substrate free of oil, grease, wax, rust or dirt. Use an airless spray at 205 Atm, 4.75 L / min, with a ratio of 45: 1 with a 0.53 mm tip. A pneumatic gun can be used for small areas. Let the product completely dry between the different layers. This system has a drying time of 12 hours at room temperature for 500 microns thickness layer. A higher substrate temperature will shorten the recovery time. A brush can be used for touch ups, but is not recommended for an application of more than 10 m²

    • Major problem

      The major problem of conventioanl thermal insulation (rock wool, glass, PU) is that it only takes into account the element of thermal conductivity whereas this element is also significantly impacted by emissivity , solar energy transmission, reflection, radiance and convection.

      In absolute terms, the thermal conductivity of MetalTec TC, that is to say the capacity of the material alone to let go of heat, is much higher than rock wool, which is laboratory tested, in an oven with high temperatures and zero humidity.

      Item 1

      This measure does not take into account the effect of moisture and humidity in calculation of thermal conductivity of rock wool: it should be known that “lambda” or K of the rockwool (thermal conductivity coefficient) is calculated at high, constant temperatures in an autoclave , with a humidity of zero %. The thermal conductivity coefficient of rock wool significantly decreases with ambient humidity. In fact, at an ambient humidity of 80%, rock wool loses about 80% of its insulating power, and this is irreversible! Imagine what happens in case of heavy rain or any cladding outdoors.

      Item 2

      Only conductivity is measured here, which is the only property of rockwool, whereas TC performs well in other registers: convection, reflectivity, emissivity, radiance and conductivity; restitution of the temperature variation on site, infrared pyrometer measurements are also distorted by the reflective properties of TC. Best way of measuring temperature on a TC surface is contact probe thermometer. The pure insulation properties of our product can therefore only be adequately measured by comparing the effect of the insulation on the contents of the receptacle. (energy retention)

      Item 3

      Of course, the added qualities of TC are: no maintenance, no rust no CUI, perfect PP, less volume, less weight, very economical spray application, no aluminum shell, insensitive to humidity, total inspectability and maintenance at all times, no climate effect, no CUI (corrosion under insulation) and guaranteed long term resistance.

      In short, the following formula is a guideline when doing calculations:

      MetalTec TC Insulating Formula = Reflectivity + Conductivity + Convection + Emissivity
      Heat transmission = Project Parameters – MetalTec TC Insulating
      Formula Without examining all parameters of the above, the coating is not compared fairly, nor does it explain the differentials found on applications.

      The spreadsheet calculations that I have derived are only a forecasting method to compare conventional insulation and the coating system and to effectively forecast the amount of coating needed to produce the result needed.
      Actual field study has shown that the forecasted calculations are very similar, although may differ due to other variables unknown.

      This calculation study now allows MetalTec TC to be effectively forecasted for engineering study. This calculation however only is applicable to MetalTec TC Coating. Other conventional insulating coatings such as rooftop derivatives cannot be examined by this forecasting method as they do not employ the same insulating principles or technology that TC employs.
