FAQ

I want to improve the wetting properties of oil-based lubricants on metal surfaces. Is it possible to reduce the surface tension?

Application:A wetting and dispersing agent that reduces viscosity and prevents sedimentation

Reply:

Adding silicone surface additives will reduce the oil’s surface tension and improve its wetting properties on metal. You can try using 0.2% of Tech-210A, Tech-2033, and Tech-2733.

Do pigments of the same color but from different manufacturers—such as (PW6)—require different dispersants?

Application:Substrate Wetting Agent

Reply:

Even for the same pigment, surface treatment processes may vary, so the optimal dispersant for each will also differ. For dispersing carbon black in solvent-based inks, we recommend Tech-6202; for dispersing organic color pigments, we recommend Tech-5350 and Tech-5835; and for dispersing titanium dioxide, we recommend Tech-598.

Can you recommend an additive for water-based inks that helps the ink wet difficult-to-wet surfaces (such as PE)?

Application:Substrate Wetting Agent

Reply:

Tech-2409 is recommended for use on various film substrates and can effectively improve the wetting and dispersion properties of water-based inks.

Our ink system is a water-based polyurethane. We’ve tried some defoamers in the past, but they caused pinholes. Could you recommend a few water-based defoamers that don’t cause pinholes or affect tran

Application:Substrate Wetting Agent

Reply:

We recommend trying Tech-3901, Tech-38101, and Tech-328W.

In water-based OPV, our coating film is relatively thick, which has led to some edge shrinkage/thickening. Are there any BYK additives that can resolve or improve this issue?

Application:Substrate Wetting Agent

Reply:

We recommend using a combination of surface additives to control surface tension and rheological additives to address the issue of narrow or thick edges. For surface additives, we recommend testing Tech-2846 and Tech-2409; for rheological additives, we recommend Tech-9022W.

We would like to screen some dispersants for our water-based inkjet inks. During this screening process, does TAIGA recommend resin-based or resin-free grinding?

Application:Substrate Wetting Agent

Reply:

Taking into account flexibility, applicability, compatibility, and pigment usage, we recommend resin-free grinding.

To improve flame retardancy, I need to increase the aluminum hydroxide content in the epoxy structural adhesive. However, when a large amount of aluminum hydroxide is added, the adhesive becomes too v

Application:Anti-sag rheological additives

Reply:

Tech-5076 improves the wetting and dispersion of aluminum hydroxide in colloidal systems and significantly reduces the viscosity of the system. It is recommended to add BYK-9076 before adding aluminum hydroxide.

Epoxy adhesives contain mineral fillers with relatively large particle sizes, such as calcium carbonate and aluminum hydroxide. During storage, these fillers settle and form hard lumps at the bottom o

Application:Anti-sag rheological additives

Reply:

Our rheological additive, Tech-9010, induces pseudoplastic behavior in colloidal systems, exhibiting high viscosity at low shear rates, which helps prevent filler settling.
