• UV/K inks are delivered in a ready-to-print adjustment. They result in a glossy finish.

• Because of the very high degree of cross-linkage of the binder, UV/K screen inks require high UV energy values for curing.

• The cured ink film shows excellent mechanical abrasion resistance and good chemical resistance.

• Due to the binders screen printing inks UV/K are not suitable for outdoor applications.

• If required, UV/K inks can be processed alternatively as 2-component ink with 5% hardener Additive UV/H to improve ink adhesion on the above mentioned substrates.

• Note on multi-layer printing: The very high mechanical and chemical resistance of the cured UV/K ink film – which is due to the high level of cross-linking – may affect intermediate adhesion. This can often be avoided by reducing the UV curing energy when curing the lower ink layer(s). However, this must be confirmed carrying out corresponding pre-trials. At the same time, you have to check if the prints still meet the resistance requirements.

• Note: Because of the variety of metals, coatings and duroplastics, pre-tests to confirm suitability of UV/K inks are essential.
