Surface Scratches on PCTG Products
Fenómeno del problema
The surface of transparent PCTG products is prone to scratches.
Análisis de la causa
The surface hardness of PCTG is low (pencil hardness around HB), and it is scratched by contact with hard objects during processing and use.
Solución
Use hard coatings (UV-cured coatings or silicone hard coatings) to protect the surface; protect properly during production and transportation.
Conclusión clave
PCTG surface protection coating is the solution to its shortcoming.
