SURFADIOLS 900
Silicone Defoamer for Solvent-based, Solvent-free and Radiation-curing Coatings and Inks
SURFADIOLS 900
(Alternative to TEGO Airex 900)
SURFADIOLS 900 is a silicone defoamer with excellent performance. It is suitable for solvent-based, solvent-free and radiation curing coatings, especially for radiation curing system and two-component epoxy system, and for paint formulation. It has a wide range of applications, including amine/amide cured epoxy floor coatings, solvent-based and radiation-cured screen-printing inks, radiation-cured varnish, wood and furniture coatings, amine/amide cured epoxy baking paint.

Special properties
Incorporation and Processing Instructions
When used in paint formulation, it is recommended to add the defoamer in grinding stage.
Mixed well before use. Addition to the coating as supplied or as a predilution is possible.
The defoamer must be mixed under high shear force.
Recommended Levels
Amount of additive (as supplied) based upon formulation weight:
Amine and amide cured epoxy floor coatings: 0.1-1.0%
Solvent based and radiation curable screen-printing inks 0.1-1.0%
Radiation curable varnish: 0.1-1.0%
Wood and furniture coatings 0.1-0.8%
Amine and amide cured epoxy baking paint 0.1-1.0%
Leather coating: 0.1-0.8%
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
