BYK-3568 brings greater individuality to the automotive

• Significant reduction of surface tension in liquid coatings
• Increased surface energy in cured coatings
• Improved wetting
• Good leveling, greater surface slip

Visually attractive, optimally protected, and outstanding
to the touch – these are essential demands on automotive OEM coatings. And yet,
in recent years, this performance profile has moved more and more towards
individualization, such as with two-colored applications, for example. Long gone
are the days when the only decision needed when buying a vehicle was between
silver, black or white – individuality is now trumps.

But in other branches of industry too, ways and means are being sought to improve
not only recoatability, but also the adhesion of stickers, printing inks or adhesives
on the coating layer, especially where optimum surface slip is also required.

It is here that BYK has the ideal additive solution in the shape of its new silicone
and polyether-modified acrylate BYK-3568. The advantages are particularly
evident in clearcoats and topcoats, for which good recoatability or adhesion of
the next coating layer is necessary. And it improves the substrate wetting as a
moderately active silicone does, while at the same time increasing not only the
coating’s surface energy but also its surface slip in a single step.

For formulators of clearcoats and topcoats who, for decades, have been using
silicone-based additives, the technology behind BYK-3568 opens up entirely new
opportunities in the fields of recoatability and adhesion, since it offers several
effects with only a single additive.
