Efka® FA 4665 is a high molecular weight unsaturated carboxylic acid combined with a very compatible organically modified polysiloxane. Acts as a dispersing agent.
Details
high-molecular-weight unsaturated carboxylic acid combined with a very compatible organically modified polysiloxane
- prevent interfacial tension between hydrophilic pigments/extenders and binder
- reduced dispersing time
- stabilization of the pigment dispersion
- reduced pigment sedimentation
- no formation of Bénard cells
- reduced tendency to “orange peel”
- prevention of flooding and floating
- improved gloss and slip
medium- to high-polarity binder systems
alkyd/amino resin combinations
nitrocellulose systems
polyurethane and chlorinated polymer systems
acrylic polyisocyanate systems (2K acrylics)
chlorinated polymers
Efka® FA 4665 should be stored in a cool and dry place.
When kept in original unopened containers, it has a total shelf life of 4 years from the date of manufacture.
