Why is Coating necessary?
Coating for automobiles started with wax. Historically people in the olden Europe started to use wax, such as pine oil to protect the wooden surface of horse carriage from rain, wind and dust. Varnish and tree resin took the place of pine oil. In the modern society wax from Carnauba palm oil has been used. Wax technologies kept evolving and found the use as effective material to protect steel plate from getting rusty and to give shine to the surface. Initially Carnauba oil was used to make wax. Later on inorganic solvents technology has developed and artificial paraffin started to be used to make wax as paraffin oil can create a layer on the surface when applied on it. What does it mean? By making an oil film, it helps reduce prism activity of sun light, and as a result, it makes it harder to find or see small scratches on the surface. Wax can temporarily maintain the shine. Thus, wax made of paraffin has been the main protection for automobiles.
Molecules of paraffin one monomers, which means paraffin has a relatively small molecule weight and a big cluster. This property means that paraffin tends to be dissolved by water and vulnerable against fluctuation of heat.
Lately, polymers or compound of iso-paraffin and acrylic silicone started to be used for coating on the automobile paint surface. As these polymers have a large molecular weight and are composed from many chemicals, they are strong against water and other atmospheric elements. They can last longer than wax. They can penetrate into paints cluster holes while wax can’t.
But the other important point is that paraffin used in wax contains abrasive particles to get rid of dust in the air. It means one time waxing can scratch approximately 0.02 to 0.05 micron to the paint and repeated waxing may give the paint scratches equivalent to the grit of abrasive paper No.1500. Subsequently, the paint begins to lose shine. It is, therefore, desirable not to unlimitedly wax the paint surface. It is advisable to take the importance of coating of the paint surface with polymer or sealant into consideration.
|Use CAR COATING:|
Currently, car coating programs* are becoming popular for the coating of the paint in the market. They are comprised of silicate dioxide and other materials. When applied on the paint surface, silicate dioxide reacts with hydrogen in the air and leaves the silicon layer on the paint surface. This silicon is 100 % inorganic material, which means it is immune to oxidation, and has static electricity prevention effect and makes the paint surface extremely smooth. This functions to keep dust and soil away from the paint surface.
(*Many of car coating programs in the market contain a large quantity of inorganic materials with a small quantity of silicate dioxide. It means they are not immune to oxidation and don’t stay on the surface for long enough).
