Who would have thought we could fight earthquakes and fires thanks to ... painting the walls?
Human creativity is endless - no one can deny this, because the evidence for that statement is present all around us, anytime, anywhere.
Even the earthquake in Japan in 2011 did not break down the paint-covered buildings.
Human creativity is endless - no one can deny this, because the evidence for that statement is present all around us, anytime, anywhere.
The face of the world has changed so much that it is the residents of this era who are surprised. If not witnessed, would anyone believe that mankind has successfully built a coating that makes the material so terribly hard?
It seems that only in this fictional film turned out to be real. And that material is Polyurea - the new pride of material science.
Polyurea possesses a lot of preeminent points that any builder wants. And maybe they will surprise you.
1. Fast and strong adhesion on many surfaces
Depending on the coated material and the amount of paint used, the drying rate will vary, but in general, Polyurea dries very quickly . Basically, after only a few hours, this process is complete, while most paints need 1-2 days to reach completion.
And if other paints are almost " not " on cold or moist materials such as steel, stone, foam . then Polyurea "accepts".
At the same time, they are almost non-volatile so they can reduce poisoning ability many times.
2. Insulated and non-flammable
The structure of polyurea is not deformed by heat. This is also a plus compared to the polyurethane brother, which is also very popular with construction. Polyurethane can be melted at high temperatures, while polyurea is not.
What about extreme heat, like when there is a fire? As with all things, they were ruined in this situation, but instead of igniting and spreading, the polyurea did not "surrender". They can extinguish themselves, or slow down the spread of fires and smoke production.
3. Very good moisture resistance
In areas with humid climates, the top concern is how to prevent the walls from getting wet, and becoming rotting or moldy.
And once again, polyurea shows its dominance. When first introduced in 1989 by Texaco Chemical Company, everyone was amazed at the experiment they were observed, when Polyurea was sprayed on the surface of a water bath.
Everyone thinks that water will neutralize this paint and dissolve it easily, but no.
The reaction rate between components is too fast, causing super-strong bonds to be created before water can penetrate into the middle. As a result, it forms a very solid block right above the water surface, while other paints will have to dissolve.
It forms a very solid block right above the water.
4. Excellent durability
This last feature is what makes polyurea more special. It is a two-step reaction chain between extended amines and isocyanate polymers that make up a flexible, non-bonding flexible membrane, able to withstand high strength forces.
Along with that is the equally attractive properties are elastic, anti-abrasion, resistance to many chemicals and cover cracks. Polyurea can even return to its original shape after being stretched to twice its original size.
However, when it was first launched, this was again the less noticeable nature of Polyurea. The awards given to this material all promote properties such as non-toxic, UV-resistant and free from acidic environment - destructive bases .
That's fine, but the problem is not enough. It was not until 2011, after the fateful earthquake occurred in Japan that people were shocked: the water tanks at a salmon farm were outside Polyurea covered intact, while a lot of work. Great process badly damaged.
This is Polyurea when sprayed on the wall.Is there a prospect?
