Sikagard® M 790
(former MasterSeal® M 790)
2-component highly chemical resistant, crack-bridging membrane based on Xolutec® for protection of concrete structures in harsh conditions
Sikagard® M 790 is a two-component crack-bridging membrane based on Xolutec® - Technology providing high chemical and mechanical resistance.
Xolutec® - a new dimension in durability
Xolutec is an innovative and smart way of combining complementary chemistries. When the material is mixed on site a cross linked interpenetrating network (XPN) is formed enhancing the overall material properties. By controlling the cross-linking density, the properties of Xolutec can be adjusted depending on the product performance required, e.g. this allows the formulation of materials with varying degrees of toughness and flexibility. Xolutec is very low in volatile organic components (VOC), is quick and easy to apply with both spray and hand application depending on requirements. It cures rapidly even at low temperature, reducing application time thus enabling fast return to service and minimizing downtime.
This technology is not sensitive to moisture and tolerates a wide variety of different site conditions, greatly expanding the application window and reducing the potential for delays and failures. Long maintenance cycles and lower life cycle costs significantly reduce total cost of ownership.
- Easy hand application by roller or trowel
- Continuous membrane: monolithic – no laps, welds or seams
- Excellent chemical resistance – including high concentrations of biogenic sulphuric acid.
- Waterproof and 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 resistance to carbon dioxide diffusion: Protects concrete from rebar corrosion.
- High tear, abrasion and impact resistance: Withstands traffic and use in areas exposed to mechanical damages.
- Tough - but flexible and crack bridging.
- Long-term durability and protection
- Thermoset: does not soften at high temperatures.
- Weatherproof: proven thundershower and freeze / thaw resistance, can be applied outdoors without additional top coating.
- Does not contain solvents.
- Can be spray-applied with selected 2-component spray machines (Please contact Sika Technical Service for details).
