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 |
