Lo-4220

Composition:
This is organic modified silicone. Prevent foam and bubble formation arising during paint production and appication in
non-polar to high poarity solventborne systems.
Typical properties:
Appearance:pale-yellow to amber-colored clear liquid.
Active matter content:100%.
Refractive index at 25ºC:1.445-1.455.
Special properties:
Silicone defoamer to prevent foam and bubble formation arising during paint production and appication in non-polar to
high poarity solvent-based systems. Lo-4220 improves the surface properties of coatings, with particular emphasis upon
leveling, increases surface slip and thus improves scratch and mar resistance. Formation of Bénard cells is prevented and
orientation of flatting agents is improved. Lo-4220 does not cause dewetting or defects in intercoat adhesion when
recoated.
Dosage:
Coil coating:   0.03-0.2%
Wood coatings:  0.05 - 0.3 %
Decorative coatings:   0.05 - 0.3 %
Industrial coatings:   0.05 - 0.3 %
Predilution in a suitable solvent simplifies dosage and incorporation.
