MasterSeal M 790
CRACK-BRIDGING PROTECTIVE COATING
Two-component highly chemical resistant, crack-bridging protective coating based on Xolutec for waterproofing and protection of concrete structures in harsh conditions.
MasterSeal M 790 is a two-component crack-bridging membrane based on Xolutec providing high chemical and mechanical resistance. This is the body coat of the MasterSeal 7000CR biogenic sulphuric acid-resistant coating.
MasterSeal M 790 is used in waterproofing applications where a high level of chemical resistance is required.
Waste water treatment plants both in the inflow and outflow areas
Sewage effluent pipelines
Easy hand application – by roller or trowel
Continuous protective coating – monolithic no laps, welds or seams
Excellent chemical resistance – including high concentrations of biogenic sulphuric acid
Waterproof – resistant to standing water
Fully bonded to substrate – can be applied to a wide range of substrates with the appropriate primer
Moisture tolerant – can be applied on substrates with high residual humidity
High water vapour permeability – low risk of blistering
High resistance to carbon dioxide diffusion – protects concrete from reinforcing steel corrosion
High tear, abrasion and impact resistance – withstands traffic and use in areas exposed to mechanical damages
Crack bridging – tough but flexible
High durability – reduced cracking tendency due to no long-term embrittlement
Thermoset – does not soften at high temperatures
Excellent adhesion – on different substrates (concrete, steel)
Weatherproof – proven thundershower and freeze / thaw resistance, can be applied outdoors without additional top coating
