ADDSiL™ 8340 is a fluorinated polyether-modified silicone leveling agent designed to provide stain resistance, anti-scratch performance, and anti-graffiti properties. It significantly reduces surface tension, improves flow and leveling, enhances hydrophobicity, and increases surface smoothness and gloss.
Excellent flow and leveling performance
Reduces surface tension significantly (<25 mN/m)
Enhances hydrophobicity and anti-smudge performance
Provides slick, soft-touch (matte) surface feel
Effective in anti-graffiti and anti-cratering formulations
Compatible with solvent-, water-, and solvent-free systems
