Koster MS Flex Foil Liquid Applied Roofing Membrane

Koster MS Flex Foil is a very easy to apply, one component, fast curing, highly elastic, UV resistant waterproofing material with very good adhesion to numerous substrates.

MS Flex Foil is an eco-friendly, premium single component, liquid applied, elastic, crack bridging waterproofing material, based on MS Polymer technology. It is characterised by excellent adhesion to a wide variety of building materials and can be applied on dry or slightly moist substrates. It is liquid applied and therefore seamless, which greatly eases application to complicated architectural details. It is characterised by a high UV resistance and stability and it is suitable for
indoor and outdoor application. The coat is fast curing and quickly resistant to rain.

It is free of solvents and therefore does not suffer from solvent evaporation in the curing process, that leads to shrinkage and consequent cracking.

Flex Foil is free of isocyanate, which in contact with moisture, releases carbon dioxide resulting in bubble formation and voids that lead to cohesive failures overtime. This allows it to be used on slightly moist substrates, unlike regular solvent base PU coats.
