BYK-UV 3510

Silicone-containing surface additive for radiation-curable overprint varnishes, to improve leveling and substrate wetting. Due to its high surface activity, BYK-UV 3510 accumulates on the surface of the coating. It is particularly recommended for radiation-curable overprint varnishes in the printing ink sector. It improves the substrate wetting and the leveling at small dosages. Generally speaking, half the dosage of a standard silicone should be sufficient to achieve optimum leveling and substrate wetting. BYK-UV 3510 is particularly suitable for high-speed machines where the decreased tendency to stabilise foam has a positive effect. Its good compatibility with standard binders enables highly transparent coatings to be produced. BYK-UV 3510 is particularly recommended for all non-aqueous, radiation-curable overprint varnishes.
