EFKA® FA 4620
Low-molecular-weight dispersing agent for inorganic pigments
EFKA FA 4620 (formerly Efka 5220) helps to wet and disperse solid particles (e.g. CaCO3, ATH) in unsaturated polyester resin systems. This results in improved wetting and incorporation of fillers and extenders, reduced viscosity of the paste/compound, and increased filler and extender loading. EFKA FA 4620 is suited for filled unsaturated polyester systems (e.g. SMC/BMC, gel coats, car putties) or combinations with polystyrene, polyvinylacetate and styrene-butadiene copolymers (e.g. LS- or LP formulations).
Product highlights
- Reduced viscosity
- Increased pigment and filler loading
- Shorter dispersing time, increased mill efficiency
