Two features are mainly responsible for the development of industrial photopolymerizable systems;

the speed of the process that transforms, in a split second, the molecule into a polymer material; production at speeds up to 400 m / min. They are applied on different supports, such as metals, plastics, paper and cardboard.

Surface properties of a material can be significantly improved by using high-strength protective coatings, such as those obtained by photoréticulation. Various types of materials are currently protected with UV coating, such as wood, plastics, fiber, paper, leather, textiles, metals, etc. The films of 20 to 100 m thick, increasing the durability of these materials by slowing down the degradation, oxidation, corrosion, aging and wear during use. The introduction of photostabilisation in the resin formulation gives a part to the coating of an anti UV filter and is used to multiply the resistance of polymer materials photoaging.

Although photopolymerization is mainly used for photographic films insolubilisation small thickness, typically between 1 and 100μm, this technology allows graticule samples much thicker. To do this, it makes at low concentrations of photoamorceurs selecting a compound that undergoes rapid photolysis without creating photoproducts absorbing in the near UV. Light radiation can penetrate progressively into the sample to initiate the polymerization of deeper layers. Various types of epoxy resins and acrylates have been reticulated by the frontal photopolymerization on thicknesses up to several centimeters. The use of solar radiation allows for the change of liquid-solid phase in a few minutes at room temperature and process large panels at a zero cost energy.
