Instant Healing VS Heat Healing
Instant healing
First of all, a knowledge: the car ppf has the ability to repair scratches because its surface has an anti scratch self healing coating, the coating protects the base film from being destroyed. When an external force acts on the coating, the molecules in the coating will be dispersed because of extrusion, as long as this external force does not destroy the coating, then when the external force disappears, the coating molecules can return to their original state on their own or under the influence of certain factors, presenting the results is the scratch repair.
The so-called “instant healing” is that after the external force disappears, the coating molecules can return to their original position on their own, without the need for other factors to affect the coating molecules. The “instant healing” sounds cool, but in fact there are many problems
One: The instant coating is actually designed to repair scratches by giving the coating molecules more room to move to resist external forces. However, for the same area of coating, the larger the molecular space, the smaller the number of molecules, the looser the structure. So instant coating stain resistance, hydrophobicity are relatively poor, such as the same rain ,instant healing car ppf more likely to appear water spots water stains.
Two: Although the coating molecules have more space to move, but there is still a limit, once the molecules exceed their own space to move, back to the original position, scratches will still exist. And poor stain resistance, easy to appear water stains, film becomes matte and other product quality problems
Heat healing
Heat healing is now has proven to be the best repair method, from the molecular structure of the coating, hot repair coating molecular structure is closely arranged, the density of its own molecules is also higher. You can understand that for the same area of coating, the molecules of the hot repair coating are “heavier and more compact”. The advantage of this structure is that scratches on the coating, because of the molecular density and tightly arranged two factors, scratches will not be very deep, naturally less likely to break through the coating. Because of the tighter arrangement, when the molecular position of the coating changes, it needs to be heated to loosen it back to its original position. Compared to second repair, heat repair is much slower, usually taking an hour at normal room temperature to repair a scratch. But warming up can make the scratch repair time shorter, which is the reason for pouring hot water or taking a heat gun to heat up the scratch during the demonstration.
So to say, the heat healing coating is the evolution of the instant healing coating, which is the result of the improvement of the product after the introduction of the instant healing coating and the problems. At present, the so-called “instant healing” products are basically faded out of the industry, because for car owners, scratch repair is only a functional feature of the car coat, what is more important is the car coat in daily use, after being ravaged by nature, the film surface can still shine as new! And this, at present, only the heat healing coating is the best choice.
CAXVINYL TPU PPF, using imported USA TPU material, mastering independent coating technology, our PPF using heat healing double nano high glossy super hydrophobic coating and heat healing double nano super anti stain anti yellowing top coat, heat quickly and automatically repair the film surface minor scratches, so that the new paint surface does not leave defects, At the same time, the dense surface structure can keep foreign pollutants out of the film, and with its hydrophobicity, it can effectively reduce the erosion of external substances, not only to provide aesthetic effects, but also have the ability to protect this aesthetic. The ordinary scratch caused by slight scraping can be repaired by itself under normal temperature or heating, and the original installation can be restored without affecting the subsequent use and protection performance.
