DELTA-SC®2580 is surface control additive for aqueous systems. It provides powerful reduction in surface tension, which leads to excellent substrate wetting, leveling and anti-cratering properties. It is suitable for coatings and printing nks. 


Composition :Modified polysiloxane 

Specific gravity @ 20°C :ca. 1.11 g/cm3 

Refractive index :ca. 1.461 

Appearance :Clear to slightly hazy liquid 

Active ingredients :>90% 

Methods of analysis can be received upon request 

Applications and usage: 


DELTA-SC®2580 is a solvent-free organically modified polysiloxane. The use of DELTA-SC®2580 gives the following advantages: 

●    Excellent anti-cratering behaviour and leveling 

●    Better substrate wetting 

●    No inter-coat adhesion problems in multi-layer applications 

●    Little or no foam stabilization 

DELTA-SC®2580 is recommended for use in all kinds of water-based coatings with a pH range of 4 - 10. 

It does not increase surface slip but if higher surface slip is required in a given system, the additional usage of DELTA-SC®2230 is recommended. 

DELTA-SC®2580 can be added prior to or after processing. In all cases care should be taken to ensure uniform distribution.

Printing inks 

DELTA-SC®2580 is a solvent-free surface control additive that greatly reduces the surface tension in aqueous printing inks. It improves substrate wetting and leveling but does not increase the surface slip. 

DELTA-SC®2230 can be added in combination with DELTA-SC®2580 to improve the slip performance. 

DELTA-SC®2580 causes little or no foam stabilization and does not affect the inter-adhesion. DELTA-SC®2580 is especially suitable for solvent-free aqueous printing inks. 

DELTA-SC®2580 can be added prior to or after processing. In all cases care should be taken to ensure uniform distribution.

Safety and Handling: 

DELTA-SC®2580 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 


DELTA-SC®2580 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. The production date is indicated on the container. 


50 kg and 180 kg non-returnable metallic containers.
