Sun Chemical High Rub Dull Matte Varnish KB-3083

Sun Chemical High Rub Dull Matte Varnish (KB-3083) is a newly developed, high-performance overprint varnish formulated for sheetfed offset printing applications that require a dull, matte finish with outstanding rub resistance. KB-3083 delivers a consistent, non-glare matte surface that protects printed pieces from scuffing and abrasion during handling, finishing, and distribution — making it an excellent choice for premium packaging, book covers, mailers, and commercial print applications where a sophisticated matte look combined with durability is required.

Formulated with non-yellowing chemistry and high solids content (91–93%), KB-3083 ensures true color fidelity and clean, even coverage without obscuring the ink film beneath. The high-rub formulation is specifically engineered to resist the mechanical wear that matte surfaces are typically more susceptible to compared to gloss OPVs, delivering a surface that holds up through bindery operations and downstream handling.

Like other varnishes in the KB series, KB-3083 dries in approximately 1.5 hours on the Josons dry time tester, enabling fast turnaround and efficient press scheduling. Its combination of matte aesthetics, high rub resistance, and oxidative dry performance makes it an ideal product for consolidating your sheetfed overprint varnish line.
