BYK-UV 3511

BYK UV 3511 is a silicone-containing surface additive for radiation-curable overprint varnishes. It improves leveling and substrate wetting at small dosages. BYK UV 3511 accumulates on the surface due to its high surface activity. It is particularly suitable for applications requiring high-speed processing where decreased foam stabilization has benefits. BYK UV 3511 provides transparent coatings due to its good compatibility with standard binders. Recommended for non-aqueous, radiation-curable overprint varnishes, BYK UV 3511 enhances substrate wetting and leveling, important for uniform, defect-free finishes in high-throughput manufacturing.
