DELTA SC® 2231

Technical Datasheet | Supplied by Delta Specialties
Organically modified polysiloxane. Is a silicone-based surface additive. Improves surface properties in all solvent-based medium to high-polar systems. Improves mar resistance, substrate wetting, leveling and anti-blocking characteristics. Increases scuff resistance, slip and surface smoothness. Prevents floating of pigments and reduce sensitivity to air-draughts. Does not influence curtain stability when applied as curtain coating. Is particularly advantageous in polyurethane systems based on hydroxyl acrylics. Can interfere with inter-coat adhesion when recoated without sanding. Has very broad compatibility with a broad range of printing ink systems. Is relatively insensitive to pin-holing even at high concentrations of the additive. Is especially effective in nitrocellulose-based systems for flexographic and gravure printing. Is also effective in UV flexographic printing. Used in wood finishes and metal coatings.
