What is 3M self-cleaning glass
This coating after coating and the surface of the chemical material, and surface molecules (such as glass or ceramic surface of the silica ), The adhesion and corrosion resistance of the coating is very strong, and the specific contrast parameters can be obtained here. In addition, the surface energy of the fluorocarbon polymer is very low (less than 10J / M2), not only the water, But also the oil has a strong exclusion effect (which is the paint itself, the decision, the first introduced the first and second types of paint is not this feature.) Therefore, its advantage is not only waterproof but also anti-oil, very good adhesion, The disadvantage is that the price is usually higher than the first two categories.Third category of products is a typical representative of the Golden Seal series.
Our common lotus leaves have this effect. Hydrophile (Hydrophile): refers to the hydrophilic molecules can be through the hydrogen bonds and water molecules to form a short bond, making the water is particularly easy and hydrophilic surface. Our common capillary phenomenon is this principle. On the market for the glass and ceramic surface of the "easy to clean paint", or "self-cleaning paint can be divided into three categories: the first category: the main component is silicone (or silicon organic resin) or other oily materials, The surface of the material gives a sense of slick, but it does not have the role of silica molecules on the surface of the material to produce a solid nano-film, but only fill our invisible surface of the uneven material, making the material smooth and uniform surface, The advantage is that water (but not on the oil) also has a strong exclusion, the disadvantage is poor adhesion, in a short period of time (6-12 months), the characteristics of its rejection of water will be significantly reduced. The second component: the main component is titanium dioxide (TiO2). In the glass plating / coated with a layer of titanium dioxide film, due to titanium dioxide (ultraviolet) light energy can produce good photocatalytic properties and has a super-hydrophilic. This super-hydrophilic property (as opposed to the hydrophobic nature of the gold seal coating), which makes small droplets converge into large water droplets, It is particularly suitable for use in outdoor architectural glass, which has the advantage of being inexpensive and has the disadvantage that it is necessary to have ultraviolet radiation, and it is necessary to use the ultraviolet light, And the same poor adhesion. The third category: the main component is fluorosilane or fluorocarbon polymer.
Easy-clean glass ", which is also commercially known as" self-clean glass, or Auto-clean glass. "It is meant to apply a layer on the glass surface After a special coating, dust or dirty liquids (including aqueous, even oily liquids) are difficult to adhere to the surface of the glass, or are easily washed with water (or rain), so that the glass surface is very easy to keep clean and Clean the glass surface of the trouble, but also can save the increasingly scarce water resources.This special coating is the so-called "easy to clean paint", or "self-cleaning paint." It is the use of objects in nature with two basic physical characteristics (Also known as "hydrophobic, English: Hydrophobe): refers to a substance (the molecules) have a strong exclusion of water." The two basic physical characteristics of the performance of the opposite, respectively: a hydrophobic Water in the surface of hydrophobic objects will form a large contact angle into a drop-like.
