Handling and storage

protect from contamination or absorption of moisture
(which can be detrimental to product quality and per-
formance).
Use
D-Foam-R C 740 is a silicone containing antifoam that
provides easy incorporation and excellent compatibility
in water based inks and coatings. D-Foam-R C 740
gives quick knock down and excellent stamina, particu-
lar in high speed, high shear applications. It is very
effective for control of microfoam.
D-Foam-R C 740 may be used in incidental food con-tact applications
in compliance with 21 CFR 175.105 or 176.210.
Typical Applications:
•Water based inks
•Waterborne coatings
•Pigment dispersions
Application Methods:
D-Foam-R C 740 is appropriate for use in pigment
grinding or coating let-down. Typical use concentra-
tions are between 0,1 and 0,4% (on total coating
weight). When added in the let-down step, best per-
formance and compatibility results are generally ob-
served after aging the finished ink or coating for at least
8 hours. As with any defoamer, formulators should
evaluate a range of concentrations to determine the
optimum dose.
