All of the relevant tests prove this: HI-MACS® has excellent chemical resistance.
HI-MACS® has a non-porous, dirt-repellent surface into which moisture cannot penetrate, with the result that even tough stains, like lipstick, acids, detergents and foods containing dyes, leave no traces on the material even after being left to work in for 16 hours.
