DELTA-SC®2777 

DELTA-SC®2777 is a silicone-free additive having high molecular weight and very broad compatibility. It is designed to reduce the surface tension of various resin systems at substrate interface, which will improve substrate wetting and levelling and prevent formation of craters without stabilizing foam. The additive provides 'long wave' levelling performance and increases gloss of the coating system and does not cause any inter-coat adhesion problems. It is highly effective in the transportation coatings when combined with the silicone-based additive DELTA-SC®2031

DELTA-SC®2777 is suitable for coatings and printing inks. 


Specifications: 

Composition :Solution of an acrylate copolymer 

Solvent(s) :Xylene 

Specific gravity @ 20°C :ca. 0.98 g/cm3 

Flashpoint :25 °C 

Appearance :Clear to slightly hazy liquid 

Active ingredients :70% 


Applications and usage: 

Coatings 

DELTA-SC®2777 has a very wide compatibility, which makes it extremely suitable for use in clear coatings. It improves levelling, prevents cratering and helps substrate wetting without damaging the inter-coat adhesion in multi-layer applications. 

It is recommended in the following application systems: 

●    Stoving enamels based on alkyd, acrylic and polyester resins 

●    Polyurethane coatings 

●    Two-pack epoxy compounds 

●    Air-dried alkyd systems 

DELTA-SC®2777 should be added at the end of the batch preparation. 

0.4-2.0% on total formulation weight 


Printing inks 

DELTA-SC®2777 is recommended for free-radically and cationically mediated UV-curable printing inks and over-print varnishes. 

It is also suitable for conventional alkyd-based printing inks and over-print varnishes, and for solvent- based printing inks. 

DELTA-SC®2777 will be effective in flexographic, screen and offset application to difficult substrates. As it does not interfere with inter-coat adhesion, trapping or over-printing is not impaired and the product is suitable for process printing. 

In over-print varnishes, DELTA-SC®2777 may be added at any stage of manufacture. 

In printing inks, addition of DELTA-SC®2777 should take place after the dispersion step. In all cases care should be taken to ensure uniform distribution of the additive. 

0.5-2.0% on total formulation weight 


Safety and Handling: 

DELTA-SC®2777 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 


Storage: 

DELTA-SC®2777 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 200 kg non-returnable metallic containers.
