4.2.
Resistance of the Front Foil Sheeting to Chemicals
4.2.1. General Resistance of the Foil Sheeting Material
AUTOTEX is based on a polyester foil sheet with a biaxial arrangement and there-
fore exhibits better resistance to solvents. It is stronger and more durable than
other sheeting materials such as polycarbonate or PVC, commonly employed for
touch pads and front face panels.
AUTOTEX is resistant to the following chemicals in accord. with DIN 42 115, Part 2,
and will exhibit no alterations for exposure periods of more than 24 hours:
