BASF is introducing the MasterSeal 7000 CR product designed to protect concrete and steel structures in aggressive wastewater environments.
It builds on the company’s new XolutecTM technology.
“Our novel Xolutec technology was developed to solve the problems of challenging technical environments," explains Roland Nowicki, Vice President, BASF Construction Chemicals Europe. "It is an innovative and smart way of combining the advantages of different chemical products and thus represents a unique solution. When the material is mixed on site, a cross-linked interpenetrating network (XPN) is formed, enhancing the overall material properties.”
The effects of wastewater in collection networks and treatment plants can lead to rapid deterioration of concrete surfaces and corrosion of concrete reinforcements and steel structures. MasterSeal 7000 CR’s high resistance to abrasion and biogenic sulfuric-acid corrosion is ideal to withstand the severe conditions that occur in pretreatment and aeration tanks, digesters, or sewers. The product possesses dynamic and static crack-bridging abilities which protect concrete, even after non-structural cracks appear, thus prolonging life cycle of the structure.
BASF reports that another key benefit of this novel resin technology is its tolerance to moisture, both in the substrate and in the environment. MasterSeal 7000 CR can be applied on very damp substrates by spray or roller, and its fast curing properties allow contact with water under pressure as soon as 24 hours after application at 20 °C.
