Abstract : Coating is a method or technique to cover the surface of the substrate with the aim of protection, decorative and other purposes. coating is a more general term for a variety of materials that can be applied as a thin layer to a surface. Paint is traditionally described as a material having a color pigment used to coat a surface, the coating may be either a liquid or a solid material. coatings are known and used since ancient times and to protect various kinds of objects and buildings. Emulsified silicone is a term generally used to describe a group of hydrophobic polymeric and monomer compounds composed of silicon-oxygen bonds and given the name organosiloxane, because of their viscosity and ability to repel water, they are referred to as oils. Polycarbonate helmet visors are the material used today. Plastic Helmet Glass (Polycarbonate) has advantages and disadvantages, the first advantage of plastic helmet glass is that it is flexible. The flexibility it has makes it more resistant to receiving impact impacts when incidents occur. Polycarbonate can withstand impacts 30 times better than glass, that's why most helmets now use this material. However, the drawback of plastic visors is that they are not scratch resistant. To resist scratches on this polycarbonate helmet glass, it must be covered with a coating.
