Dow Corning Corp. has
developed a new Syl-Off
®
solvent-free
silicone release coating system that delivers long-term anchorage on
unprimed polyester.
The system includes a base
coating, an anchorage additive, a choice of crosslinkers and a platinum
catalyst:
- Syl-Off SL
9106 Coating
- Syl-Off SL
9176 Anchorage Additive
- Syl-Off 7689
Crosslinker or Syl-Off 7028
Crosslinker
- Syl-Off 4000
Catalyst
This system’s base
coating/anchorage additive combination offers excellent adhesion to both primed
and unprimed polyester films. Applications that benefit from this feature
include filmic pressure-sensitive laminate and labelstock, single- and
double-sided industrial polyester release films, and release liners for
polyester technical adhesive tapes.
A lower-cost alternative to
ultraviolet (UV) cure systems, the new Syl-Off
system uses cost-effective thermal-cure technology. And the system’s excellent
bath stability gives manufacturers more processing flexibility with less
potential for waste.
Release is naturally low at
slow peel speed with a flat release profile, but a range of release force
values can be achieved when the system is combined with Syl-Off 9156
Release Modifier. Release stability against both solvent
and water-based acrylic adhesives is excellent.
The Syl-Off SL 9176 Anchorage Additive component is also useful for
achieving anchorage in coatings for polyethylene, polypropylene and paper
substrates as well as demonstrating benefit in fluorosilicone and PSA primer
applications.
