| Résumé : |
A company has introduced a new waterborne technology for exterior masonry paints. The authors explain how it works.
Hydro Pliolite is a new waterborne technology for exterior masonry paints. Based on innovative EBS (Emulsified Binding System) technology, it combines the advantages of water-borne paint formulation with outstanding adhesion, allowing application without primer.
Paints based on Hydro Pliolite resins have a deep matt texture and can be produced in a wide range of shades from delicate pastels to the deepest colours. They can be applied to all types of masonry surfaces, whether old or new. They are both porous and water-repellent, with the result that facades are not only decorated but also enjoy a lasting protection.
Exterior masonry or facade coatings represent one of the most dynamic and largest markets for paints in Europe. The first and easiest segmentation is made between solvent borne and water borne paints.
The former represents about 30% by volume of the market and is particulary strong in some countries (France, UK, Italy, Spain, Portugal ...). The key benefits being "the all-weather application and strong adhesion on mineral surfaces.
It is well known and accepted that film formation of solvent borne paints is less affected by climatic conditions (temperature and relative humidity), and that the minimum film formation temperature (MFFT) is very low(<-30°C). Last but not least, solvent borne paints are still widely used to prime difficult and chalky surfaces. They are the preferred choice for the renovation of old surfaces because of their ability to penetrate and bind porous substrates.
The waterborne offer can be divided between organic coatings (often described as latex or dispersion paints), organic silicone paints (siloxane paints), and mineral paints (silicate paints). In this article, we will focus only on the two first categories. |
