FAQ
Inkjet
What types of additives are used to reduce dynamic surface tension?
Application:Inkjet
Reply: Tech-264 and Tech-267 are highly effective at reducing dynamic surface tension and are particularly suitable for wetting substrates during high-speed printing.
What surfactants or combinations of surfactants would you recommend to improve the wetting and penetration properties of water-based varnishes and paper coatings?
Application:Inkjet
Reply:
Tech-2846, Tech-2033, and Tech-2733 are silicone-based surfactants that improve the wetting properties of water-based inks and varnishes on various substrates. For silicone-free formulations, we recommend Tech-181W and Tech-182W.
How can the wetting and leveling of acrylic UV inks on aluminum oxide substrates be improved?
Application:Inkjet
Reply:
UV inks can achieve good substrate wetting with both silicone-based and non-silicone additives: Silicone additives: Tech-2033, Tech-2733; non-silicone additives: Tech-181W, Tech-182W.
For PVC-based inks containing silver powder, what additives can be used to improve the wetting and dispersion of the silver powder?
Application:Inkjet
Reply: Using Tech-541 or Tech-6192 can help achieve good wetting and dispersion of the silver powder.
What additives are used to disperse organic pigments in water-based inks?
Application:Inkjet
Reply: For water-based resin-free color pastes, we recommend Tech-690 as the dispersant; for resin-based color pastes, we recommend Tech-6076 as the dispersant.
What additives should be used to improve the anti-settling properties of inorganic and metallic pigments?
Application:Inkjet
Reply:
For solvent-based systems, we highly recommend Tech-9010L. Depending on the polarity, you may need to test different additives. In most cases, the usage rate is around 0.1–0.2%; for water-based systems, we highly recommend Tech-9012L, with a usage rate also around 0.1–0.2%.
In water-based inkjet printing, it is necessary to control droplet shape and ejection performance. Are there any recommended additives?
Application:Inkjet
Reply:
We recommend trying: Tech-181W is a silicone-free, macromolecularly modified acrylate, and Tech-2550 is a silicone-containing, macromolecularly modified acrylate.
