Reversible Thermochromic paints for construction
Reversible Thermochromic paints react with a colour change to a change in temperature. The colour disappears after reaching a limit temperature, together with temperature increase, and vice versa – it reappears after the limit temperature is reached, with decrease in temperature.
The process of change begins at a specific tempreature, then the transformation of colour (discolouration together with the increase and recolourisation with the decrease) lasts in a range of several degrees. The colour change is reversible – after reaching the initial temperature the paint returns to its original colour.
A designer is able to shape the image depending on the thermal conditions of the surroundings, colour it when it is cold, and discolour it when it is hot.
Surfaces may react to the heat of a human body or other temperature sources, thermochromic floors with footprints remaining on them, walls reacting to the touch, ice or warm air, building facades with thermochromic coatings, which change colours under the warmth of sunrays, ceramic bathroom tiles or floor tiles which change colour when exposed to warm or hot water, heaters changing colours after turning the heating on.
By designing architectural devices with the help of thermochromic paints, a user plays a kind of a game with the installation coated with such paint, using available means of temperature change such as the heat of a human body, heating devices, coolness of the ice, etc.
