PERFORMANCE PROPERTIES CHEMICAL RESISTANCE Finished products are laminated to aluminium panels and allowed to dwell for 24 hours prior to testing. Test conducted at room temperature. Testing consisting of five cycles of 10 min immersions in the specified test fluid, followed by 30 min recovery periods. After final immersion, samples rubbed 10 times with cotton swab saturated with test fluid.
