MasterSeal 7000 CR System for Extreme Wastewater Challenges

Waterproofing and concrete protection system for aggressive wastewater environments.

System components:

MasterSeal 7000 CR consists of two components, both based on Xolutec™ technology:

• Primer MasterSeal P 770 (two-component). Acts as a bonding promoter.

• Membrane MasterSeal M 790 (two-component). Crack-bridging.

Features and benefits:

• Quick and easy application by roller or spray at temperatures from 5–35°C.

• Fast curing properties, which reduces downtime and allows contact with water only 24 hours after application.

• High abrasion and chemical resistance, including a resistance to high concentrations of biogenic sulfuric acid.

• Has a high moisture tolerance, even when applied to humid substrates.

• Crack-bridging for gaps of up to 0.7 mm, therefore helping to extend the life cycle of the concrete structure.

• Available in two colours - both of which allow for safe application in areas with poor visibility.

• Uses Xolutec™ technology, which aims to provide a durable solution in challenging environments by forming a cross-linked interpenetrating network (IPN). The technology enhances overall material properties, has extremely low volatile organic compounds (VOCs) and is quick and easy to apply.

• Fully bonds to steel and concrete.

• The system has been tested over a five-year period at the Fraunhofer Institute under conditions that simulate those of a real sewer. The results of the test show no significant changes on the properties of MasterSeal 7000 CR.

Applications:

Suitable for horizontal, vertical and overhead application, as well as indoor and outdoor application. Can be used in the following areas:

• Urban and industrial facilities for wastewater treatment, in both inflow and outflow areas.

• Biogas plants.

• Secondary containment in industry.

• Pre-treatment and aeration tanks.

• Sewage effluent pipelines.
