Silicone Defoamer D-066N For Polyurethane And Polyester Solvent-Based Coatings

(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
