Polyurethane Polyester Solvent Coating Silicone Defoamer D-066N
(Analogue to BYK-066N)
First, component
Breaking bubble polysiloxane solution
Second, typical physical information
Appearance: Colorless transparent liquid
Effective amount: 0.8%
Density (20℃): 0.95-1.05g/ml
Solvent: xylene
Third, recommended addition
0.1-1% of Total formula amount
Fourth, adding method
In order to gain sufficient defoaming effects, defoamer should be
added before grinding. If add it at the later period, then shear stress should be high enough to guarantee the defoamer to disperse enough, in case of shrinkage
cavity.
Fifth, characteristics and advantages
It is kind of general use organosilicone defoamer and has good
defoaming and foam-depressing properties. It is easy to control and
hard to produce shrinkage cavity because of over added.
Sixth, applied areas
The additive is widely used in dry solvent systems under normal
temperature, including polyurethane, polyester, nitro, crylic acid
and so on.
Seventh, shelf life
12 months, start from the day of production
Eighth, storage
Keep away from heat, stored at ventilated, shady, cool and dried
places
Ninth, package
25kg/packing
