| Résumé : |
In the last ten years there has heen a strong development of radiation-curable coatings. These coatings consist of low molecular weight polymers dissolved in monomers capable of addition polymerization. When exposed to electron beams or to ultraviolet radiation, the system is converted to a solid crosslinked coating within a fraction of a second. Instead of evaporating like other solvents,the monomers are incorporated into the coating. Hence radiation cured coatings are 100 percent active systems. All of the materials employed are used. There is no waste, no air pollution and hecause the cure rate is so rapid, it makes possible line speeds up to 1,000 feet per minute (1), faster than a conventional coating can be applied hy any existing method.
In addition to these general advantages of high speed and low pollution, other advantages particularly applicable to leather are available with radiation curable coatings. These are energy savings, improved leather quality, tougher coatings, probable greater arec yield of product, close control of the depth of polymer impregnation and probable applicahility of impregnation to full grain leathers. These potentialities are discussed in this paper. |
