Dow Corning Unveils Advanced Water-based Emulsion for Off-line PET Film to Deliver Greater Sustainability, Safety, Performance

Dow Corning, a global leader in silicones, silicon-based technology and innovation, introduced here today at Labelexpo Europe 2015 (stand #7E35), new Syl-Off® EM 7945 Coating, the company’s new water-based silicone emulsion developed for off-line coating of polyethylene terephthalate (PET) films. Syl-Off EM 7945 Coating is a more sustainable and safer alternative to solvent-based release coatings, which it can replace without incurring additional costs. The new emulsion also delivers higher performance vs. traditional release coatings, including faster cure, superior anchorage, lower release force and excellent aesthetics. This advanced new technology, which complements Dow Corning’s expanding family of high-performance coatings, is ideally suited for clear-on-clear labeling and electronics applications.

“Dow Corning’s leadership in release coatings is based on our proven ability to proactively give our customers the innovative material technologies they need to compete and succeed in today’s fiercely competitive marketplace,” said Kris Verschueren, global market segment leader, Packaging, Dow Corning. “Our new Syl-Off EM 7945 Coating is the latest example of our commitment to staying ahead of changing customer requirements.”

The unparalleled 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 and enhanced sustainability.

Syl-Off EM 7945 Coating’s suitability as a release coating for PET substrates makes it a leading candidate for clear-on-clear labeling for food contact, cosmetic and beverage applications. The new Dow Corning solution is also a high-performance 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.

Compared to other emulsion release coatings, Syl-Off EM 7945 Coating combines good anchorage and fast cure while producing less rainbow. It 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 switching suppliers and modifying equipment.
Dow Corning’s Syl-Off EM 7945 Coating is available globally.
