Definition of Pigments

Pigments are generally coloured, organic or inorganic solid powder, and usually are insoluble. They are not affected physically or chemically in the substrate in which they are incorporated. Pigments can give a full range of colours.


Types of pigments

Inorganic Pigments: Those pigments that are made up of mineral compounds are known to be Inorganic Pigments. These minerals are mainly oxides, sulphides of one or more metals.

Organic Pigments: In organic pigments, the molecules are made of carbon atoms along with hydrogen, nitrogen or oxygen atoms. Organic pigments are carbon based and are often made from petroleum compounds


The Differences between Organic and Inorganic Pigments


Inorganic pigments

Organic pigments


Minerals Chemically refined oil


Often dull


Opacity Opaque


Light fastness

Very good Vary from poor to good

Dyeing/Coloring Strength



Cost Moderate

Mostly too expensive




Color is simply defined as the light of different wavelengths and frequencies. Light, however, is just one form of energy that we can actually see that is made up of photons.

Colour comes from light. We can see even main colours of the Visible Spectrum. The retinas in our eyes though have three types of colour receptors in the form of cones, we can actually only detect three of these visible colours – red, blue and green. These colours are called additive primaries. It is these three colours that are mixed in our brain to create all of the other colours we see. The wavelength and frequency of light also influences the colour we see. The seven colours of the spectrum all have varying wavelengths and frequencies. Red is at the lower end of the spectrum and has a higher wavelength but lower frequency than that of violet at the top end of the spectrum which has a lower wavelength and higher frequency. To physically see this, we need a prism. When light from the sun passes through a prism, the light is split into the seven visible colours by refraction. Refraction is caused by the change in speed experienced by a wave of light when it changes medium.


About Wet-pour Rubber Surfacing

Wet pour rubber surfacing is becoming a very popular choice for playground safety surfacing. Its combination of aesthetic appeal, nearly limitless design potential and unmatched non slip characteristics make it a strong candidate for playground surfacing.

Wet pour rubber surfacing is used in a wide variety of applications, from playground safety surfacing, to running tracks, on pool decks and patios and even in water parks and on cruise ship decks. The surface must be able to withstand a tremendous amount of wear and tear from foot traffic, the elements and most of all the sun.

A typical wet pour system consists of a cushion layer composed of recycled tyre rubber that is buffed or ground to specific sizes and a wear course layer made of EPDM (Ethylene Propylene Diene Monomer) granules that come in a variety of colors. The cushion layer and the wear course layers are held together by either an Aromatic or Aliphatic binding agents and typically installed over a crushed stone, asphalt, or concrete sub-base.
