Model and Parameters
SHORT DESCRIPTION:
1935 is mainly composed of modified polysiloxane, it is a silicone defoamer with excellent
performance, which has good defoaming, leveling and degassing effect.
FEATURES:
1935 has high defoaming efficiency without appearance of fish eyes and poor adhesion problem.
It is suitable for water-based formulations and can remove stubborn foams. It has very good
compatibility, and, it can be used in the formulations with a variety of leveling agents and wetting
agents etc. It can be applied in strong acid and strong alkali aqueous systems. It is widely used in
varnish and paint formulations. It is suitable in water-based pure acrylic emulsion, styrene-acrylic
emulsion, vinyl and EVA emulsion, PU dispersion and those mixed systems, etc.
TYPICAL PROPERTIES:
Index Result
Appearance Milk-white liquid
Solid content 25~30%
Density 1.01
pH value 6.0~9.0
Viscosity(25°C) 1000~3500mPa·s
APPLICATIONS:
1935 is especially suitable for water-based industrial coating systems, architectural coatings,
water-based inks, overprint varnishes, water-based wood, furniture coatings and parquet floor
paints, water-based metallic paints, automotive paints, amino baking varnishes, transparent
industrial paints, leather coatings, washing agents, etc.
APPLICATION PROCESS:
In order to fully disperse the defoamer, it is best to stir before use. It can be added in the let-down
stage, pre-diluted or directly added to the paint as supplied. The long-term effectiveness of
defoamers depends on the system and should be tested in different formulations (experiments at
different temperatures are recommended). It can be added after the foam is generated or added
to the product as an antifoam component.
Recommended dosage:
0.1-0.3% of the total amount. The above recommended levels can be used for orientation.
Optimal levels are determined through a series of laboratory tests.
