Description

MasterSeal 7000 CR's high resistance to abrasion and biogenic sulfuric acid corrosion are ideal to withstand the severe conditions that occur in pretreatment and aeration tanks, digesters, or sewers. Its dynamic and static crack-bridging abilities protect concrete from cracks thus prolonging the structure's life cycle.

Product properties

• Fast and easy application by rolling or spray
• Excellent curing properties, which reduce downtime
• Specific chemical resistance, including high concentrations of biogenic sulfuric acid
• Crack-bridging for gaps of up to 0.7 mm
• Maximum moisture tolerance, including application on humid substrates

Challenges in wastewater Treatment

• Strong waterflow and water containing solid particles > Abrasion
• Concrete shrinkage and steel reinforcement corrosion > Cracks, leakage and structural damage
• Presence of chemicals and conditions for Biogenic Sulfuric Acid > Chemical attack

Fields of application

• Urban and industrial wastewater treatment both in inflow and outflow areas
• Biogas plants
• Secondary containment in industry
• Sewage effluent pipelines
