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.
Composition :Solution of an acrylate copolymer
Specific gravity @ 20°C :ca. 0.98 g/cm3
Flashpoint :25 °C
Appearance :Clear to slightly hazy liquid
Active ingredients :70%
Applications and usage:
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
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.
