For the stabilization of the transparent iron oxid Sicotrans yellow 1916 I selected DISPERBYK-190. The resin free grind…

the gelling of the water-based resins. If you like to prevent the gelling you can add 1-5% DISPERBYK-102 into the slurry grind in combination with DISPERBYK-190

Even there is no demand for aqueous clear coats at the moment I would like to prepare for the future with such a system.…

For substrate wetting you should use 0.2-0.5% of a silicone surfactant like BYK-345 , BYK-349 or BYK-3455 . To increase the anti crater properties and for a…

How can we avoid seeding when using LAPONITE-RD in water-based base coat?

First LAPONITE has to be added slowly into demineralized water while stiring. This avoids the formation of gel particles. Also it is important only to add the…

Which product can you recommend to stabilize organic pigments in waterbased inks?

We recommend DISPERBYK-190 for aqueous pigment concentrates (resin free), for resin containing concentrates we recommend DISPERBYK-193 .

We have applied different water-based systems via airless spray application. Dependent on the resin used, some systems…

BYK-1786 (0.3-1.0% as delivered on total formulation) is recommended for a broad range of water-based systems which are applied via airless or airmix spray…

Can you give me your best rheology additive? I need good sag resistance and good leveling in my water-based 2 pack PU…

Rheology behavior can have a huge influence on leveling, if the coating has strong pseudoplastic behavior with a high viscosity in the low shear range it can…

I have a cratering problem in my aqueous coating with a water-reducible resin and a co-solvent amount of ~15%, how can I…

common to use defoamer, if the defoamer is too strong or not well incorporated this can lead to crater as well. In any case the surface tension of the coating…

How can I get metallic orientation in aqueous refinish basecoat. I have good experience with the EVA wax Cerafak-106 in…

has to be done with rotation viscosimeter. If higher flop values are necessary you can combine the AQUATIX 8421 with Laponite RD.

Which additive can be used to create a deep matting effect in a waterbased floor top coat formulation?

offers wax additives which can be used directly in waterbased coating formulation. AQUAMAT 208 or CERAFLOUR 927 N offer matting effects and can be used directly…

Can you recommend a suitable rheology additive for a xylene based alkyd paint?

want to use a liquid rheology additive, you can use RHEOBYK-7411 CA (Poly urea) or RHEOBYK-430 . These products can be post added. A possible clay based…
