POLICAM PMMA (polymethylmethacrylate) and polycarbonates (PC) sheet used in many sectors such as furniture, decoration, building materials, lighting have optical properties. They are thermoplastic polymer sheets with a maximum usage temperature of 80 ° C. Thermoplastic polymer with amorphous structure is quite transparent and has the closest permeability to glass. Its density is half the density of glass and it is light. Fabrication applications are very easy. It is preferred instead of glass. Surface scratches are seen in areas of use in the environments where it is exposed. Surface improvement applications can be made with functional coatings. Sol-gel method is one of the most widely used methods because it is easy and useful in functional coating of ceramic, glass and plastic surfaces. In this study, the sol gel method was preferred for coating PMMA and PC plate surfaces. The prepared functional coating is applied to PC and PMMA sheet surface in certain thicknesses by means of an applicator. The improvements seen on the plate surface after the coating has cured have been controlled. Surface scanning with SEM, anti-scratching of the surface with pencil hardness test, and permanent properties on the surface were determined by artificial aging.
