| Résumé : |
The author discusses how the right inorganic pigment can be the right solution for exterior painting tinting systems.
Colour is an excellent way of personalising your home, helping your company's brand stand out or expressing how you Peel.
High public demand for colour has been confirmed by market research on pigments, which show not only an increase in demand for colour but also the considerable potential for a wide range of hues, as a resuit of the colour solutions available.
One of the rnost common ways of incorporating organic and inorganic pigments into paint is dispersion in liquid. The pigment or pigment paste to be used must be chosen carefully and accurately on the basis of the context in which it is to be used.
When exterior colour is called for (so-called façade paints) the choice of pigment is crucial to the development of tinting systems because it is necessary to guarantee the paint's performance when it is exposed to environmental conditions, such as rain, sun, heat and cold.
Tinting system development hinges on the need to encompass the greatest range of colours in the widest variety of available paints and products (acrylic and alkyl paints, etc) including mineral paints (silicate and silicone-based) and external thermal insulation systems (External Thermal Insulation Composite Systems, ETICS).
Clearly the challenge is in obtaining the widest range of colours possible, whilst maintaining high performance standards for exterior
In this article I will attempt to analyse the delicate equilibrium, which exists between the chemical make-up and the structure of inorganic pigments, their colour hues, their pigmentation capacity and their performance when exposed to the sort of atmospheric conditions and aggressive environments characteristic of outdoor surfaces. |
