The choice of colour and resistance of paints depends to a large extent on the environment and the conditions to which the painted surface will be exposed.
If we talk about façade paints, we can say that they are the calling card of a building. On exteriors, since façades are exposed to the vagaries of the weather, it is crucial to choose paints that are resistant to rain, sun and other elements.
In terms of colours, the choice is often aesthetic, but can also have practical considerations, i.e. how it will look over time and how it will blend in with its surroundings.
For example, light colours can help reflect light and keep surfaces cooler, while dark colours can absorb more heat.
High stability pigments are essential in applications where colours are to remain unchanged over time, resisting factors such as light, heat, exposure to air and other environmental elements. Pigments must have these characteristics:
1. Lightfastness: these pigments must be able to resist degradation caused by ultraviolet radiation and prolonged exposure to sunlight.
2. Thermal stability: They must maintain their colour even under high temperature conditions.
3. Weather resistance: Pigments must be able to withstand the effects of weather, rain and other outdoor elements.
4. Chemical resistance: They must be stable against exposure to chemicals, avoiding changes in colour or degradation.
5. Good adhesion: They must bond effectively to the substrate to ensure a durable application.
Specific pigments that are known for their high stability include certain metal oxides, titanium dioxide and selected organic pigments and are widely used in the manufacture of exterior paints, and other applications where durability and colour stability are critical.
Our Lucarex range of pigment pastes are specially designed for outdoor exposure with full guarantee of durability and colour longevity.
A selection of pigments have been used in this range of pigment pastes to achieve a spectacular variety of vivid, intense and luminous shades.
These pastes are perfectly suitable for exterior paints and are based on siloxane, silicone, silicate, cement containing systems, long oil alkyds and enamels.
