New Silicone Materials For Controllable Slip And Antiblocking Performance In Uv Curable Overprint Varnishes

The usage of ultra violet (UV) cured coatings has undergone considerable growth over the last 15-20years. Much of this growth has been at the expense of more traditional solvent borne systems, driven by the trend to reduce solvent emissions and to reduce energy costs associated with cure and application for environmental product improvement. Associated with this growth has been the development of increasingly sophisticated performance enhancing materials that enable formulators to meet the increasingly demanding needs of end users. This class of materials includes silicone based products. It is the aim of this paper to describe recent developments at Dow Corning in this field.
