BYK-W 972 is a polyurethane-modified Wetting Dispersing Agents engineered for SMC/BMC and pultrusion processes. This additive simultaneously addresses phase separation prevention in PS-UP blends and enhances fiber wetting in HMC systems, while optimizing pigment dispersion stability for organic/black pigments in low-shrink formulations through its unique polymer architecture.
Dual-Function - Combines phase stabilization with fiber wetting enhancement
Color Consistency - Uniform pigment distribution in LS systems
Mechanical Optimizer - Improves fiber-resin interfacial bonding
Process Adaptor - Compatible with PS-UP hybrid chemistries
High-Load Capability - Supports up to 140% pigment loading
Automotive SMC - Class A surface body panels
Electrical BMC - High-strength insulating components
Pultruded Profiles - Structural building sections
HMC Components - Performance-critical composite parts
Pigment Concentrates - Organic/black pigment stabilization
