Photoluminescent & Retro-Reflective Pigments

Photoluminescent Pigments are characterized by their ability to absorb and store light energy and release this energy for a long period of time in darkness. This cycle of absorbing-storing-emitting is infinite. Applications are found in coatings, inks, paints and polymers for novely and safety uses.

Retro-Reflective Pigments are comprised of aluminum coated spherical glass beads and strongly reflect the incident light. The major use is in traffic and safety sign boards for road safety application. Other uses such as reflective clothing are also popular.

Photochromic Dyes & Invisible UV/IR Fluorescent Pigments

We offer a wide range of photochromatic dyes. These are light sensitive dyes, which have several applications.

Photochromic Dyes

These dyes are mainly used in ophthalmic lenses. Apart from this, they have application in :
  • Children's toys
  • Agricultural films
  • Novelties
  • Packaging
  • Security markers
  • Clothing
  • Cosmetics


Invisible Pigments are undetectable to the eyes after incorporating into paint, ink or polymer. When irradiated with specified UV/ IR radiation, they will fluoresce brightly and be clealry visible. They are of considerable use in security, coding, marking, sorting, identification and tracer applications. We offer these pigments in variety of packaging options to customers at very competitive prices.

Complex Inorganic Colour Pigments or Mixed Metal Oxide Pigments

Complex Inorganic Colour Pigments (CICP) are based on mixed metal oxides. Due to their production via a calcination process at high temperatures of 700-1300 degree C, they exhibit excellent, heat stability, lightfastness, chemical resistance and weather fastnesss properties.

Optical Brightening Agents or Fluorescent Whitening Agents

Optical Brightening Agents Agents are also known as Fluorescent Whitening Agents (FWA) and are useful in masking the inherent yellowness in plastics, lacquers, paints, inks, photographic solutions and fibres. These Optical Brighteners function by absorbing light in the invisible UV spectrum and emitting light in the visible blue region (400-500 mm) via a fluorescent mechanism. The end result is a brighter and fresh appearance also known as whiter than white or ultra white. These are also useful in brightening of other color pigments and increasing the jetness of black pigments.

Clarifying or Nucleating agent is a high performance sorbitol based substance that reduces haze and enhances the clarity of polypropylene through nucleation of the polymer.

Polyolefin Colorants & Cosmetic Colorants

Gem-Tone Polyolefin Colorants & Cosmetic Colorants are a new class of polymeric dyes available for use in clarified polypropylene. The materials are amorphous, resinous, high molecular weight dyestuffs. They are easily handled as a dry powder and incorporate well into polyolefins under normal processing conditions. They offer superior clarity, extraction and migration properties. They have received FDA approval.
