Sun Chemical Gloss Hard Dry Varnish

Sun Chemical Gloss Hard Dry Varnish (KB-3047) is a newly developed, high-performance overprint varnish formulated for sheetfed offset presses requiring outstanding gloss levels and rapid dry times. KB-3047 delivers a bright, hard gloss finish that enhances the visual impact of printed pieces, making it an excellent choice for premium packaging, commercial printing, and high-end marketing materials where surface quality is a priority.

Formulated with a non-yellowing chemistry and high solids content (91–93%), KB-3047 ensures color fidelity and excellent coverage with minimal coating weight. The varnish dries in just 1.5 hours on the Josons dry time tester — significantly faster than many comparable oxidative-dry OPVs — enabling press operators to reduce press downtime and accelerate bindery turnaround without sacrificing finish quality.

Its unique combination of excellent gloss, high oxidative dry performance, and non-imprintable surface makes KB-3047 an ideal product for consolidating your sheetfed overprint varnish line. By replacing multiple specialty OPVs with a single high-performing product, printers can streamline inventory and reduce waste.
