UV Resistance: Ultraviolet (UV) radiation, from sunlight, accelerates the chemical and physical degradation of FRP moldings exposed to outdoor conditions. The degradation occurs mostly on the surface of the molding. But once degraded, the surface tends to chalk and erode due to weathering, exposing fresh surface to further attack. Protection of outdoor structures fabricated in FRP is, therefore, important. Kerox Pigments absorb and convert UV radiation into heat, which is dissipated to the surrounding medium readily. Therefore, pigments prolong the outdoor service life of composite moldings. Protection by this mechanism depends on the pigment concentration on the surface. Gel coats having higher pigment loading will, therefore, afford longer protection.

Manufacture of composites involves a concoction of raw materials - resins, catalyst, accelerators, mold releases and glass fiber. The resin:catalyst:accelerator ratio always poses a technical challenge, since they are sourced from disparate manufacturers. Often when the resin fails to gel, or reach its peak strength, it is complex to pin-point the problem raw material. Is it the resin, or the catalyst, or the accelerator, or all? What about the time and money to debug to the problem and to compensate for the loss in product?

Kerox Polyurethane Pigment dispersions consist of organic and inorganic colorants dispersed in an engineered vehicle that is fully compatible with commercial grades of polyols. These can be used for coloring Cast Molded Components, Sports Surfaces, Roofing & Flooring, Military Camouflage, Injection Moulding, Medical & Prosthetics, Safety Wear, Molds & Tool Making, Pipeline Coatings, Motor-homes, Boats, Trucks & Buses, Automobiles, Shoe Soles, Foam Bedding, Sports Equipment, Machine Housings and Display Signages.

These are dispersions of inorganic and organic compounds in a special grade of unsaturated polyester resin vehicle, which cross links during curing with commercial grades of Gelcoat and GP resin systems. These are dispersions of inorganic and organic compounds in a special grade of saturated polyester resin vehicle, which functions as a plasticizer in commercial grades of Epoxy resin systems.
