Persistency Of The Front Overlay To Solvents - VWR T Serie Bedienungsanleitung

6.5.

Persistency of the front overlay to solvents

The front overlay is based on a polyester foil with a biaxial alignment and has therefore a higher persistence against
solvents compared with e.g. polycarbonate or PVC. It is stronger and more durable than other foils generally used for
plastic foil keyboards and front panels.
The material is resistant against following chemicals over a period of more than 24 hours without any perceptible
changes:
