2. What are these coatings?
ď‚—Hydrophobic Coatings is the name we can also give to Liquid Glass Coatings.
ď‚—Hydrophobic Coatings makes any surface resistent to water, oil and other liquids.
ď‚—Thanks to the protection they give to the surface, drops of liquid are repelled and they do not get into it.
ď‚—Hydrophobic coatings can be also used in absorvent surfaces.
3. Performance in absorvent surfaces
ď‚—It is more difficult to understand the performance of hydrophobic coatings in absorvent surfaces, as they usually let liquid get into them easily.
ď‚—In the other hand in absorvent surfaces it is easier to see how it works as it is more surprising.
ď‚—In order to know how hydrophobic a surface is, we have to look at the drops. The less they are in contact with it, the more hydrophobic is the surface.
4. Performance in non-absorvent surfaces
ď‚—Surfaces such as glass may seem hydrophobic to the naked eye, as they seem to repel liquid.
ď‚—Non-absorvent surfaces have small holes in which liquids and contaminants can adhere and spoil the surface.
ď‚—If we apply hydrophobic coatings to these porous surfaces, the holes will be protected and the surface will be able to repel any liquid.
5. How does it work in non-absorvent surfaces?
ď‚—Once we use hydrophobic coatings in a non-absorvent surface, there are two test we can make in order to check its hydrophobic capacity.
ď‚—Speed test The quicker the liquid is repelled, the most hydrophobic the surface is.
ď‚—Beading test When a liquid is spilt over a surface it shears all over the surface, but when this surface is hydrophobically protected the liquid stays together in little beads.
