SYL-OFF™ Solventless Release Coating Solutions for Paper

SYL-OFF™ solventless release coating solutions for paper

For pressure-sensitive adhesive applications that call for solventless release coatings, Dow offers a complete “toolbox” of solutions with a solid track record of proven performance.

Our family of SYL-OFF™ solventless solutions for release coatings can help reduce vulnerability to upward swings in platinum metal prices – while also enabling the processing convenience, line speed and release performance you need:

  • Reliable, robust cure below 35 ppm platinum
  • Record-breaking line speeds
  • Improved conversion speeds and easy of dispersing
  • Increased flexibility in controlling release, cure and cost
  • Good coverage, bath life, anchorage and release stability

Complete toolbox

The SYL-OFF™ family of products includes everything you need for a wide variety of applications:

  • Silicone release coatings
  • Crosslinkers
  • Release modifiers and catalysts

In addition, Dow offers two inhibitor systems – Acetylenic alcohol and Maleate – each with a number of choices for coating, modifier, crosslinker and catalyst options. See the table below to learn more about which options would work best for your application.

Processing and performance features

Inhibitor Acetylenic alcohol inhibited coatings Maleate inhibited coatings
Cure Lower extractables at a given dwell time; shorter dwell time/higher line speed More robust cure versus bath age
Bath life > 8 hours at 40°C at 40 ppm platinum > 6 hours at 40°C at 40 ppm platinum
Thin-film stability   Longer thin-film stability
Coverage   Better coverage versus coat weight
