In developing ORMOCER® coatings, we have also taken into account the growing demand for UV-curable coatings. The hardness of an ORMOCER® coating can now be applied to thermally sensitive substrates by means of UV-curing, so that high curing temperatures are no longer necessary. Special reactive organic groups allow the curing of ORMOCER® coatings by means of UV-induced polymerization reactions which hardly generate any heat at all. The desired hardness of the surface is obtained in just a few seconds. Apart from providing scratch resistance, UV-curing also offers many other application areas for ORMOCER® coatings.
