to solvents and environmental influences.
The film usually used is based on a polyester film with biaxial orienta-
tion, which therefore has a better resistance to solvents. It can with-
stand pencil hardness 3HB.
The front film is able to withstand over 24 hours exposure to the fol-
lowing chemicals at 50°C without visible damage. Concentration 100%
