Hydroxyethyl Cellulose(HEC) for Exterior Paints

· Products

Water-based paints are mainly used for the protective and decorative coating of interior walls and ceilings but are also used for exterior applications.Paints, in particular with a high pigment volume concentration (PVC), owe their good processing properties to HEC. Although the amount of coating auxiliaries is very small, it can improve the performance of coating remarkably. So hydroxyethyl cellulose has become an indispensable part of coatings. Thickener is a rheological additive. It can not only thicken the coating, prevent sagging in the construction, but also give the coating excellent mechanical properties and storage stability. Hydroxyethyl cellulose is a very important additive for low viscosity waterborne coatings.

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. Celopro® is mainly used as rheological modifier and enhances the film formation of the binder.

 The use of Celopro Hydroxyethylcellulose optimises the following properties of coating:

  • Consistency for application
  • Water retention
  • Binding power
  • Storage stability

Furthermore, open time, spattering, levelling, hiding power and film formation of the coating material are enhanced by the use of cellulose ethers.

Celopro® H  grades with a medium viscosity level are recommended.
