Paper or Plastic? New Developments in Siliconizing Filmic Substrates

摘要

The use of filmic release liners is growing, fueled by high-value "no-label" look applications. In addition to their ability to deliver optical clarity, films possess beneficial properties, such as strength, hold-out and surface smoothness that are likely to increase market interest and consequently application growth. Different films present different challenges, including anchorage, low-temperature cure requirements and the need for release modification. However, major technology breakthroughs occurring in thermal solventless release coatings are making it easier to overcome those challenges. UV-curable and especially the new low-temperature-cure solventless silicone systems designed especially for films are likely to out-pace solvent-based systems as the preferred vehicles for siliconizing film.
