New solvent-free dispersant improves ink flow in white UV-ink systems
With its high pigment and filler loadings, Efka® FA 4611 enables mill base viscosity to be substantially reduced and rheological behavior improved in UV curable systems.
This new dispersant (copolymer with acidic groups) provides excellent stabilization of inorganic pigments, in particular titanium dioxide. Efka® FA 4611 is broadly applicable, due to its solvent-free character and compatibility with a wide range of resins, including UV acrylic, polyurethane and unsaturated polyester. It is also very suitable for high gloss UV systems.
Specially designed for solvent-free systems, Efka® FA 4611 offers the following benefits in UV curable systems:
- Strong reduction of mill-base viscosity
- Improved rheological behavior
- High pigment loading
- Broad compatibility with a wide range of resin systems (e.g. UV acrylic, PUR, UPE)
- No negative influence on gloss
Efka® FA 4611 can be used in both solvent-based and solvent-free industrial and OEM/refinish coatings, wood coatings, printing & packaging, and composites.
