Features and Benefits

VOK ®- UV3530 is an organic silicon surfactant that will gather at the film/substrate interface in the waterborne radiation curing system. Its acrylate functional group enables it to be cross-linked into the polymer network, so it can be permanently fixed on the interface, thus preventing the migration of silicone surfactant. Due to its strong surface tension reducing effect, VOK ®- UV3530 can improve the wettability of substrate. In the nonaqueous radiation curing system, it will be arranged at the film/air interface to improve leveling.

Recommended use

VOK ®- UV3530 is specially recommended for water-based radiation curing printing ink and varnish. It has limited applications in nonaqueous systems.

Recommended dosage

0.2-1% auxiliary dosage (purchase form) is based on the general formula.

The above recommended dosage is for reference, and the appropriate dosage shall be determined through a series of tests.

Adding method and processing guidance

It can be added at any stage, including after.
