  • Water based coating: safer and easier to handle
  • Suitable for wide range of coating techniques
  • Applications: from clear-on-clear labeling to pressure-sensitive PS tapes

Dow Corning has introduced a new water-based silicone emulsion developed for off-line coating of polyethylene terephthalate (PET) films. Syl-Off EM 7945 Coating is an alternative to solvent-based release coatings, which it can replace without incurring additional costs. The new emulsion offers higher performance versus traditional release coatings, including faster cure, superior anchorage, lower release force and very good aesthetics. This new technology is ideally suited for clear-on-clear labeling and electronics applications.

Water based coating: safer and easier to handle

The sustainability and safety of Syl-Off EM 7945 Coating make it an attractive choice for customers seeking to reduce the environmental impact of manufacturing. Because it is water based, the new emulsion is safer and easier to handle and apply during the logistic and coating processes. Besides avoiding or minimizing volatile organic compounds (VOCs) with its solvent-free formula, Syl-Off EM 7945 Coating offers the possibility to use very thin coat weights for cost-effectiveness.

Applications: from clear-on-clear labeling to pressure-sensitive PS tapes

The coating’s suitability as a release coating for PET substrates makes it a possible candidate for clear-on-clear labeling for food contact, cosmetic and beverage applications. It is also an option for use in pressure-sensitive (PS) tapes that aid in the manufacture of consumer electronics devices, including touchscreens and light emitting diode (LED) displays and liquid crystal displays (LCDs). The use of PS tapes instead of fasteners to hold sensitive electronic components in place before and during the assembly process allows for lighter devices with more functionality.

Suitable for wide range of coating techniques

Syl-Off EM 7945 is also easily used with a wide range of coating techniques, including direct and off-set gravure and Rod/Meyer bar. Importantly, it can replace other solvent-based systems without the costs associated with modifying equipment.
