BYK-W 9011 Wetting Dispersant Agents

BYK-W 9011 is an acidic copolymer Wetting Dispersant Agents designed for SMC/BMC and pultrusion processes. This solvent-free additive optimizes filler/pigment dispersion in low-profile (LP), low-shrink (LS), and highly filled epoxy systems, reducing viscosity while enhancing batch consistency.

Effect of BYK-W 9011 Wetting Dispersant Agents

  1. Filler Specialist - Superior dispersion for CaCO₃/ATH fillers

  2. Viscosity Reducer - Enables 20-30% higher filler loading

  3. Emission Control - Complies with low-VOC requirements

  4. Process Stabilizer - Improves batch-to-batch reproducibility

  5. Economic Option - Budget-friendly vs. BYK-W 9010

Typical Applications of BYK-W 9011 Wetting Dispersant Agents

  1. Automotive SMC - Class A surface body panels

  2. Electrical BMC - Insulating enclosures with stable viscosity

  3. Structural Pultrusion - Fiber-reinforced profiles

  4. Fire-Retardant Composites - ATH-filled formulations

  5. Epoxy Tooling - High-fill mold manufacturing
