How Resistant is the Xypex Coating to Aggressive Chemicals?
Based on independent testing according to ASTM C 267-77 Chemical Resistance of Mortars, the Xypex coating is not affected by a wide range of aggressive chemicals including mild acids, solvents, chlorides and caustic materials. Because Xypex is pH specific (not chemical specific) it will protect concrete from any chemical whose pH range is 3.0 to 11.0 constant contact, or 2.0 to 12.0 periodic contact.
