DELTA-SC® 2031 

DELTA-SC® 2031 is a silicone surface additive to provide good substrate wetting of critical substrates and excellent anti-cratering by reduction of surface tension of the coating systems. It also improves surface slip, scratch resistance and anti-blocking properties. 

DELTA-SC® 2031 is a heat resistant silicone additive, which shows no thermal decomposition at temperatures between 150°C and 230°C. Due to its low surface tension, it prevents floating of pigments, Bénard cells and pinholing. It is suitable for coatings and printing nks.

Applications and usage: 

Coatings 

DELTA-SC® 2031 is compatible with all medium- to high-polarity solvent-based systems. 

It is suited for: 

    ●    Wood finishes based on unsaturated polyesters, polyurethane and nitrocellulose. It is also suitable for UV-curable wood coatings 

    ●    Metal coatings, e.g. transportation coatings. DELTA-SC® 2031 improves levelling, mar- resistance and acts as an anti-blocking agent. It can interfere with inter-coat adhesion when recoated without sanding. If used in conjunction with DELTA-SC® 2777, good flow and slip properties can be obtained, especially in top coats. If air is introduced by the application equipment, small amounts of defoamers such as DELTA-FC® 1020 and DELTA-FC® 1022 should be added. 

    ●    Acid-curing and stoving coatings 

It can be added at any stage of manufacture as long as sufficient shear forces are applied to ensure uniform distribution of the additive.

Printing inks 

DELTA-SC® 2031 improves substrate wetting, levelling and increases scuff and mar resistance in inks and over-print varnishes. An applied film containing DELTA-SC® 2031 is relatively insensitive to pin- holing. It is especially effective in nitrocellulose-based flexographic inks and UV-curable over-print varnishes. 

DELTA-SC® 2031 can be added at any stage of the manufacturing process. In all cases care should be taken to ensure uniform distribution.

Safety and Handling: 

DELTA-SC® 2031 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 


Storage: 

DELTA-SC® 2031 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. 


Packaging: 

50 kg and 190 kg non-returnable metallic containers.
