Definitions
- the invention relates to a method for sealing surfaces using a one-component, moisture-curing coating composition which is isocyanate- and bitumen-free. More particularly, the invention relates to a method for sealing exterior and interior building surfaces, roofs and the like.
- a major disadvantage of aqueous emulsions is the physical drying of the materials, which becomes very slow, especially at a temperature of 15 ° C.
- the Drying at the surface above 25 0 C comparatively quickly, so that it can lead to water inclusions and subsequently to the formation of bubbles. This creates weak spots in the coating, which can lead to leaks.
- One-part polyurethane-based sealant systems typically contain large amounts of solvent to lower the viscosity for a roofing application or roll application to an acceptable level.
- Two-component polyurethane systems are very expensive in comparison and require a complicated application technology. All polyurethane waterproofing systems contain highly toxic isocyanate compounds, the use of which is critical in almost all home improvement, but also in many craftsman applications.
- RTV-I silicone coating formulations such as acetate or oxime systems, give malodorous or even deleterious cleavage products upon curing, e.g. Acetic acid or oxime, from.
- Other disadvantages of these materials are the poor adhesion to a variety of building materials, the poor paintability and the insufficient weathering stability.
- One-component moisture-curing coating compositions based on MS polymers are known as sealing materials for use in the construction industry from EP 1 695 989 A, WO 2007/093382 and WO 2008/077510.

- EP 1 036 807 A is known, the efficiency of this final termination in the manufacturing process for the conventional, commercially available MS polymers with a maximum of 85% is relatively poor.
- all non-terminated end groups are ultimately unreactive and form "dead chain ends"
- Coating formulations based on MS polymers always have substantial residual tack which results in rapid fouling and is accordingly undesirable - especially in roofing applications.
- MS polymer-based formulation must achieve greater than 25 wt% MS to achieve acceptable mechanical properties Polymers as a comparatively expensive formulation component, as is known from WO02 / 093382.
