    ChEMICAL RESISTAnCE

(24 hOUR ExPOSURE)

Test procedure The test was conducted by applying 5 drops of each reagent on the surface, covered with a watch glass (except those marked**). Chemicals marked ** were tested with a saturated cotton ball covered by a bottle. All chemicals were tested at room temperature for a period of 24 hours, rinsed off with water and evaluated.

Test results no effect: No detectable stain, loss of gloss or change in work surface material. Excellent: Slight stain or loss of gloss, but no change to the function, smoothness or life of the work surface material. Good: A clearly discernible stain or loss of gloss, but no change to the function, smoothness or life of the work surface material. Fair: Unacceptable staining or discernible deterioration or etching of the work surface material. Failure: Severe stain or moderate deterioration, pitting cratering or etching of work surface material.
