The disadvantage of acrylic is that it is softer than metal and its surface is easily scratched.
However, there is an acrylic that prevents scratching.
That is an acrylic called hard-coated acrylic, an acrylic with a coating agent to increase the hardness of the surface.

1. characteristics and properties First, as the name “hard coat” implies, the surface is hardened. Generally, the surface hardness of plastic plates (including polycarbonate, etc.) is 2H, which is the hardness of a pencil lead, and scratches will occur. Hard-coated acrylics can withstand scratches up to 6H, making them much more resistant to abrasion and scratch. It will not be scratched in the environment of daily use. In addition to scratch resistance, it also has excellent optical properties, weather resistance, and smoothness. 2. intended use Used for parts that are affected by scratches. Small LCD full-face protective panels for cellular phones, etc. TV full surface panels Full surface of monitors Soundproofing plates for expressways Window glass for vehicles Various building materials, etc. 3. model number Model numbers of hard-coated acrylics differ depending on the manufacturer. Mitsubishi Chemical MR series: Thickness 0.5 to 15 mm Nitto Plastic Industry: Hard-coat panels with a thickness of 0.2 to 5 mm Nitto Jushi Kogyo hard-coated plates with thicknesses ranging from 0.2 to 5 mm, etc. We use hard coated boards from both companies above. Conclusion Acrylic has the advantage of excellent transmittance, but it also has the disadvantage of being susceptible to scratches. Generally, scratching acrylic with fingernails causes scratches, so it is one idea to use hard-coated acrylic for areas where you do not want scratches, although it is more expensive than regular acrylic. In addition to acrylic, polycarbonate is also available as a hard-coat material. Since the coating is made by heat treatment, it is not suitable for bonding, bending, or lasers.
