EFKA FA 4620
EFKA FA 4620
EFKA® FA 4620 belongs to the family of low-molecular-weight wetting and dispersing agents. It is well suitable for use in solvent- and water-based as well as solvent-free systems.
It is very efficient in wetting and dispersing fillers, extenders and inorganic pigments, particularly TiO2. This results in:
- reduced viscosity
- increased pigment and filler loading
- shorter dispersing time, increased mill efficiency
EFKA® FA 4620 can be used as sole dispersing agent together with resins, inorganic pigments and fillers. When combined with high-molecular-weight dispersants it can also be used for systems with organic pigments.
Applications
EFKA® FA 4620 is suitable for a broad range of resins. It is recommended for:
- automotive refinish coatings (inorganic particles, metallics)
- water-based industrial coatings
- solvent-based industrial coatings
- coil coating, especially TiO2
- composites (unsaturated isophthalic polyester [UPE] combinations)
- gelcoats, sheet- and bulk-molding compounds
- water-based architectural coatings
- solvent-based architectural coatings (high-solids and long-oil alkyds)
EFKA® FA 4620 can be used for systems ranging from nitrocellulose to high-solids alkyds, unsaturated polyester systems (gelcoats, sheetand bulk-molding compounds), coil coating and water-based systems (in which neutralization to above pH 7 is recommended).
