BYK-P 9928 is a polymeric ester Wetting Dispersing Agents designed to eliminate bubble formation during MEKP-catalyzed vinylester resin curing. This specialized processing aid modifies peroxide decomposition pathways without compromising corrosion resistance or curing performance, enabling bubble-free composites while maintaining standard MEKP compatibility and resin storage stability
Bubble-Free Curing - Converts oxygen generation to radical participation in polymerization
MEKP-Compatible - Works with standard peroxide curing systems
Process-Stable - Maintains 6+ months stability in pre-accelerated resins
Performance-Preserving - Minimal impact on gel time/corrosion resistance
Easy Handling - Liquid form for straightforward incorporation
Marine Composites - Hull laminates requiring void-free structures
Chemical Tanks - Corrosion-resistant vinylester linings
Wind Energy - Rotor blade resin infusion processes
Pipes/Flanges - High-pressure industrial piping systems
Architectural Panels - Gel coat applications demanding surface perfection
