BYK-220S is an organosilicon-based Wetting Dispersing Agents designed for solvent-based coatings and ambient-cure plastic systems. This additive enhances pigment stabilization through controlled flocculation while improving surface smoothness and flow characteristics. Its unique formulation integrates polysiloxane copolymers for superior matting agent and aluminum flake orientation in industrial applications
Flocculation Control - Forms 3D pigment networks to prevent floating/flooding
Surface Optimizer - Combines slip and leveling properties via polysiloxane technology
Viscosity Reducer - Lowers grinding paste viscosity for higher pigment loading
Universal Stabilizer - Effective for inorganic/organic pigments and fillers
Process Adaptor - Compatible with ambient-cure resins (UP, PU, epoxy)
Industrial Coatings - Machinery/equipment finishes with high gloss
Architectural Paints - Exterior wall coatings with anti-settling properties
Plastic Composites - UP/EP resin systems for SMC/BMC molding
Metallic Finishes - Aluminum flake orientation in automotive coatings
Gel Coats - Pigment stabilization for marine/construction applications
