Frequently asked questions for
Here are some of the most frequently asked questions with their answers from Inkjet Inks.
BYK-DYNWET 800 is an alcohol alkoxylate and provides excellent reduction of the dynamic surface tension and thus improves substrate wetting as well. Second recommendation: BYK-3400.
BYK-346 and BYK-333 are silicone surfactants and will improve the substrate wetting of water-based inks and overprint varnishes on various substrates. Silicone-free recommendations are BYK-381 and BYK-DYNWET 800.
For better substrate wetting of UV inks we suggest the usage of the following products:Silicone-containing: BYK-377, BYK-UV 3510 Silicone-free: BYK-381 in higher dosage
BYK-016 was especially developed for printing inks used in food packaging applications and is silicone-free.
We recommend DISPERBYK-190 for waterborne pigment concentrates (resin free) , for resin containing concentrates we recommend DISPERBYK-193.
RHEOBYK-D 410 is our first recommendation for solvent based inks. Depending on the polarity it might be necessary to test a different additive. The dosage is approximately 0.1.-0.2% in most systems. For water-based systems RHEOBYK-D 420 is our first recommendation. The dosage is at a similar level 0.1-0.2%.
