Same Source Coating Additive with Dowsil 29 Additive DC-29

Apr 17, 2023

Dow Corning®29 Additive Equivalent in the market supplied by SILIBASE SILICONE

Composition:Polyether siloxane copolymer

Product Name: Silicone Surfactant
Item No.: SilibaseCP-2829

Description: SilibaseCP-2829 silicone surfactant is one carbinol functional silicone glycol surfactant used to provide leveling and wetting
and improve gloss.

FEATURES & BENEFITS

  • Paste
  • Enhances flow, leveling and gloss
  • Compatible with acrylic, epoxy, polyesters and urethane systems
  • Can prevent pigment flotation

Typical data:

Appearanceamber-colored clear liquid (become solid below 15ºC)

Active matter content100

Refractive index at 25ºC1.436-1.440

Viscosity(25ºC)300-600cp 

Special properties:

  • Excellent anti-blocking, release assistance with gloss and softness.
  • Improves wetting, leveling and spread-out.
  • Excellent compatibility with PU resin and stay release paper used repetitiously.
  • Endblocking glycol contains active hydroxyl group, which is reactive with organic polymers like polyurethane.
    Therefore, it is chemically reacted in the network and increases hydrolytic stability of the resin. 

APPLICATIONS

SilibaseCP-2829 silicone additive has been successful in these industrial applications:

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

Dosage (additive as supplied):

  • 0.1-0.5on total formulation as leveling additive.
  • 1%~5% as a resin modifier.
  • Predilution in a suitable solvent simplifies dosage and incorporation. 

HOW TO USE

SilibaseCP-2829 silicone 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.

SilibaseCP-2829 silicone additive is generally effective at concentrations typically ranging from 0.2–1.0 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. SilibaseCP-2829 silicone additive is compatible
with acrylic, epoxy, polyesters, and urethane systems. Thorough preproduction
