  DISPARLON L-1980N, L-1982N, L-1983N, L-1984N, L-1985-50N are polyacrylate surface-active agents. They contain no silicones or fluorocarbons.



ADVANTAGES:
100% Active
Improve flow and leveling
Prevent pinholes, craters and orange peel
Excellent recoatability
Promote pigment wetting and dispersion
Promote air release and inhibit foam
 



APPLICATIONS:
The L-series leveling agents are designed for use in solventborne or solvent-free systems. Please use the product listing below to determine the best leveling agent for your application. The products are arranged in order of decreasing polarity.
L-1985-50N:
Highest polarity for coatings containing methyl ethyl ketone, ethanol and methanol.
L-1980N:
Recommended for use in polyester/melamine and urethane coatings and in unsaturated polyester applications.
L-1984N:
Recommended for acrylic coatings including high solids melamine and two component urethanes. L-1984N has lower surface tension than L-1980N and can be used where greater wetting is required.
L-1982N:
Recommended for high solids alkyd coatings as well as epoxy and phenolic applications.
L-1983N:
Lowest polarity and surface tension make it suitable for use in epoxy primers and epoxy/acrylic UV cure inks.
