Dyes & Pigments in Construction Industry
The construction industry as a whole includes the
- Construction of buildings for either residential purpose or
commercial purpose or industrial purpose or as an integrated form.
- Heavy and civil engineering construction. It includes sewers,
roads, highways, bridges, tunnels etc.
- Specialized constructions like carpentry, painting, plumbing and
But, here we will know about the use of color pigments in the
construction industry as a whole. The different applications of pigments
in the construction industry are as follows:
Greater the solar radiation, higher will be the heat
absorption by the roofs of the houses. To dissipate the heat, 'Cool
Coating' technology has been invented. This new technology focuses on
reflecting solar radiation. If traditional pigment colors are used for
coating, the roof will absorb infrared radiation. Therefore, a new type
of pigments has been taken for this purpose. These pigments are called
as Cool Pigments. The advantage of these pigments over the traditional
pigments is that they absorb less infrared rays from the sun.
For coating purpose, two types of pigments are used.
They are Organic pigments and Inorganic pigments. Organic pigments gives
various bright colors, but, these colors are not very lightfast and
opaque as compare to inorganic pigments. Inorganic pigments are used for
those applications where color warranty should be there against sunlight
and other natural elements. For metal roofing, a special type of
pigments are used, which is called as 'Complex Inorganic Colored
Painting or Paint Analysis is a very common
maintenance project in all building, including commercial. Residential
and production purposes. By applying a new coat of paint on the walls of
the building, can change the appearance of the entire building. It also
brings a new touch of fashion in this regards. Thorough analysis of
paint can give the knowledge about the composition of various pigments
which are used in the paint.
The Durability of Buildings
Most new technological paints are moisture aversive
in nature. Some improved technological pigments are used in these types
of paints. When these paints are used on the wall, then these paints
prevent moisture from entering the walls.
In the recent years, people are most concerning about
the safety in the public buildings and at workplaces. Some incidents in
the underground railway stations and crowded public places, has drawn
out attention towards the various safety measures. For this purpose,
some safety-way guidance systems have been brought into existence. In
these systems, some glowing pigments like phosphorescent pigments are
used. Under darkness, due to power failure, these materials in the
system start to glow brightly. This thing helps the people to find out
their rescue way. Generally, these systems are fitted in the safety
passages, public buildings, factories, stations & tunnels, ships
Wooden materials are frequently used in all kind of
construction works, right from houses to factories, from bridges to
railways. But, unfortunately, we don't give reasonable care on the
preservation of these wooden materials. So, it will be better for all of
us if we conserve the wooden materials instead of their replacement. To
conserve these wooden materials, various coating and painting methods
have been developed. In each kind of coating and painting methods, some
specific kinds of pigments are used.
Before the placement of the concrete, pigments are
mixed with it to create color. This is the most common method of
concrete colorizing. The quantity in which the pigments are mixed and
the proportion of their mixing can be altered. By altering these
proportion and quantity, the color varieties can be brought in the
Tiles, Metal Panels, and Shingles
Pigments are used in various commonly used
house-roofing products. These pigments are used in tiles, metals, panels
and shingles. Various cool pigments are used today for coating concrete,
clay tiles and metal panels.
of Construction Materials & Pigments
Up to a certain extent, what will be the quality of
the end products of various constructions, depends upon the choice of
the pigments. After years of observation and testing of colored
concretes in different sites, it can be said that inorganic oxide
pigments have a high degree of fastness properties.
Colored asphalt is used in the traffic direction, for
sporting facilities, in gardens, at school yards and squares. Now, it
should have different attractive colors for different uses. The color
fastness and durability will depend upon the pigments and the proportion
in which they are combined with each other.
