Exterior paints
Exterior paints are used for decorative design as well as for protecting surfaces from the destructive influences of weathering. Suitable substrates include renders (mineral and polymer based), concrete, brickwork and other coatings.
Exterior emulsion-based paints protect the subsurface by forming a sealed, flexible film. This coating film has low water vapour permeability and acts as an effective barrier against acidic gases (carbon dioxide, sulphur dioxide). Because of the reduced water absorption, the facade is protected for many years against damaging effects of water and driving rain. Exterior emulsion-based paints can be coloured with all types of weather-resistant organic and inorganic pigments. Tylose® is mainly used as rheological modifier and enhances the film formation of the binder.
Tylose® H/HS- and MH-types with a medium viscosity level are recommended.
Coating materials
Due to numerous properties, Tylose® is an important component in water based paints. The most essential properties of Tylose® for the optimisation of coatings are; adjustment of consistency, water retention, binding power and the function as a protective colloid.
