Dow Corning Introduces Low-cost, Low-platinum, Silicone Release Coating line

Published on 2004-09-15. Author : SpecialChem

Midland, Michigan, USA - Dow Corning Corporation has introduced a low-cost, solventless, silicone release coating line designed to help customers defend themselves against rising platinum prices and other cost-related issues without sacrificing performance.

Syl-Off® Advantage Series release coatings enable significantly lower platinum usage - 20-50 ppm vs. the 100 ppm or more that conventional systems require. Luc Dusart, Dow Corning's global pressure sensitive industry marketing manager says, "In many high-volume applications, such as the production of paper release liners, this can result in a 10-15% cost savings in silicones."

Syl-Off Advantage Series is a complete solventless, platinum-catalyzed, thermal-cure release coating system. It includes a comprehensive selection of base polymers, crosslinkers, release modifiers and catalysts that enable flexible control of cure characteristics, release profile and costs. Mr. Dusart says one of the unique benefits of the Dow Corning system is that users do not have to compromise on bath life, anchorage, line speed or release stability.

Two versions of the system are available to accommodate different needs for low-temperature cure vs. needs for longer thin-film bath stability in hot, high-speed processing operations.

According to Associate Industry Scientist Loretta Jones, "In customer trials, these new polymer and crosslinker architectures have yielded remarkable cure performance with very low platinum requirements." Ms. Jones also reports that converters are able to achieve faster stripping speeds during label converting, due to the flatter release profiles available from the range of Advantage Series coatings.

Suitable for a wide variety of adhesives and applications, Syl-Off Advantage Series silicone release coatings can be used to augment or replace a coater's current product line. Moreover, they are designed to minimize the processing and performance difficulties that users sometimes encounter when changing release coating formulations. Advantage Series products have viscosities similar to those found in Dow Corning's standard platinum-catalyzed, solventless, silicone release coatings. Equipment, substrate and dwell time requirements are also similar.

To ensure the successful implementation of Syl-Off Advantage Series, Dow Corning's technical support team offers comprehensive changeover and trouble-shooting assistance, including pilot coating and application testing support.

Dow Corning provides performance-enhancing solutions to meet the diverse needs of more than 25,000 customers worldwide. Offering more than 7,000 products and services, Dow Corning is a global leader in silicon-based materials. The company is equally owned by The Dow Chemical Company and Corning Incorporated. More than half of Dow Corning's sales are outside the United States.
