Dow Corning® 29 Additive
Carbinol functional silicone glycol surfactant used to provide
leveling and wetting and improve gloss
USES
Dow Corning ® 29 Additive has been successful in these industrial
applications1:
To improve leveling and wetting:
Ink Solvent-based flexographic ink
Water-based letterpress ink at 0.2-0.5%
Coating Solvent-based coil coating
Solvent-based overprint varnish
To provide gloss:
Coating Solvent-based coil coating
HOW TO USE
Dow Corning 29 Additive is effective
at low concentrations. The amount
required depends on the type of
formulation, the solvent it contains,
resin system and total system solids.
Dow Corning 29 Additive is generally
effective at concentrations ranging
from 0.2-2.0 weight percent, based
upon total formulation. This
additive can be added during the
grind, let down or be post-added.
Characteristics may vary when used
with different systems and
formulations. Dow Corning 29
Additive is compatible with acrylic,
epoxy, polyesters, and urethane
systems. Thorough preproduction
testing is necessary to ensure
expected performance.
RESULTS OF ULTRAVIOLET
OVERPRINT VARNISH
STUDIES
This data is based on a laboratory
study. The control in both of these
studies consisted of the formulation
with no additives added.
In Formulation 1, Dow Corning 29
Additive increased the mar resistance
over the control by 18 percent.
The 20° gloss of the overprint
varnish was not compromised to
provide increased mar resistance.
In Formulation 2, Dow Corning 29
Additive provides a 76.6 percent
increase in the distinction of image
(DOI) thus indicating and improvement
in appearance of the automotive
topcoat.
Improves leveling and wetting in solvent-based coil coating,. Provides gloss in solvent-based coil coating. (ABA copolymer, polylethylene oxide glycol type)
Effective at low concentrations. Recommended usage level: 0.2-2.0 weight percent, based upon total formulation. Can be added during the grind, let down or be post-added.
