H-633 leveling agent
polyether modified polysiloxane
CAS：67762-85-0
FEATURES
H-633 leveling agent is effective at low concentrations. The amount required depends on the type of formulation, Provides slip, gloss enhancement,，pigment treatment and leveling for ink and coatings applications. Provides mar resistance for coatings applications
TYPICAL PROPERTIES
Appearance Clear-to-hazy amber liquid
Specific Gravity at 25°C (77°F) 1.03-1.04
Viscosity at 25°C (77°F) cs 800-1200
Cloud point °C (1%water solution):43-45
H-633 Additive has been successful in these industrial applications1:
To improve leveling:
Water-based (ink, industrial coating , paint) at 0.05-1% (based on solids)
Solvent-based (plastic coating paint) at 0.05-0.5%
Solvent-free paint at 0.3 -1%
F-333 additive can be added during the grind or let-down, or can be post-added.
Characteristics may vary when used with different systems and formulations. Thorough preproduction testing is necessary to ensure expected performance.
Packaging & storage：
25L,200L plastic drum or IBC。
Store in seal drum at room , dry place , usable life 1 year.
