MasterSeal M 790

CRACK-BRIDGING PROTECTIVE COATING

Description

Two-component highly chemical resistant, crack-bridging protective coating based on Xolutec for waterproofing and protection of concrete structures in harsh conditions.

Uses

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.
This includes:

Waste water treatment plants both in the inflow and outflow areas

Sewage effluent pipelines

Biogas plants

Secondary containment

Advantages

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
