◈Background
Silica Aerogel can be used in coatings to improve thermal insulation and hydrophobic performance of the coatings. But it is
very important to select right form of aerogel to achieve target performances.
Only a few years ago, it was impossible to mix aerogel to other materials. Due to this reason, we have developed “wet-Aerogel”
which can be mixed into other materials easily. And then, we have developed two kinds of products finally!

With “Aerogel-W”, We have developed 4types of aerogel coatings. In Korea, Several large companies already have been using this aero-coat-series.
Especially, Aerocoat-300 is being applied to components of complex structures (engine part, pipe curved sections…etc) in which insulation is
needed or which existing insulation blanket can not cover.

Aerogel Blanket
Firstly, the existing blanket has no Hydrophobic. so the blanket absorbs the moisture
and eventually shrinks. Therefore it causes the inconvenience of having to replace the
blanket after a certain period of time.
In case of aerogel blanket, although it has made up on the weakness of existing blanket, aerogel
blanket experience the process of oxidation due to the oxygen created from the gap between the
pipe and the surface of aerogel blanket during the construction process

High Temperature Resistance
However, our aerogel coating fully supplements the weakness of blanket.
• firstly, our aerogel coating is hydrophobic
• second, when coating the “aero-coat” to the pipe, we can completely avoid
oxidation corrosion because there is no oxygen involved.
• thirdly, in order to attach a the blanket to the pipe, it must be measured and
constructed separately which requires a lot of technicians. but our product only
requires one to mix the ingredients in the right proportions and just spray them.

Conclusion
Solution - A
We also agree with you about Dry time issue. If you are concerned about Dry-time,
we recommend you to see following solutions.
The insulating performance improves and the threat of crack decreases as the
temperature inside of pipe increases. And of course, it will shorten the time gap of
the coating time. If there’s a device inserting steam into the pipe to increase the
temperature.
Please try to apply to pipe systems with Aero-coat-
300.
If you want to develope new system to insulate for
higher temperature (maximum 300 ℃) applications
such as steam. Also You can lower volume of pipe
by installing aerogel coating system than now.
Our “Aerogel Coating”is an excellent insulator!!
