I have a gelletion on epoxy pigment paste during storage. Especially on red and blue colors. What could be the reason…

Many wetting and dispersing additives contain a lot of anchor groups which can react with epoxy resin. Though this problem is more prominent with organic…

We are using solspere 26000 for grinding of irgazine red and cinquasia violet with Tio2 and we observe viscosity pick-up…

acidic treated TiO2) is the best choice (1.5% solid additive on TiO2). If this is a co-grind (grinding all pigments together), calculate for each individual…

We are facing issues with proper leveling in a solvent-free radiation-curing system but need to formulate silicone-free.

functionality BYK-UV 3535 reacts with the radiation-curing system which leads to a long-lasting effect without any migration. Recommended additive dosage is…

I have formulated a matt solvent-borne 2-pack polyurethane system by applying an untreated silica based matting agent to…

BYK-320 and BYK-323 are less active silicone surface additives which equilibrate the surface tension differences within the coating during solvent evaporation…

At the moment, we are developing a new epoxy coating. This coating has contact to drinking water, thus it has to be…

seperate raw materials, do not have an approval. That is a difference to FDA 175.300 for example. But there is a positive list, where you can list raw…

Which additive can be added to a waterbased polyurethane clear top coat to control the bubble-formation, when the…

Air in these systems impacts the final coating properties in a tremendous way. PU flooring systems combine optical appearance with excellent mechanical…

I am working on a TiO2 pigmented solvent free epoxy. I have found severe loss of hiding while curing. TiO2 disperes…

This problem mainly occurs due to flocculation of titanium dioxide. To avoid this kind of phenomena, correct additive and correct additive dosage are both…

Which additives can be used to prevent craters, Bénard cells, pinholes or orange peel if an epoxy floor coating is…

One very significant parameter that has an impact on all these defects is the surface tension, or more specifically, the surface tension differences. The…

Which additives can be used to improve and avoid surface defects like air entrapment, poor substrate wetting or crater…

additives are available. BYK-A 535 is especially recommended for air release if these systems are formulated with MDI or TDI prepolymers. BYK-A 535 fully meets…

Do you have a silicone-free defoamer for water-based systems?

BYK-016 was especially developed for printing inks used in food packaging applications and is silicone-free.

Do you have a defoamer recommended for UV inks?

Silicone defoamers for UV ink application are BYK-1799 and BYK-088 . Silicone-free recommendations are BYK-1752 , BYK-1790 and BYK-1791 . First recommendation…

We would like to increase the optical performance of our water based top coat. Do you have a product to improve the…

BYK-378 is a high molecular silicone additive, which migrates to the top of the surface and increases the leveling and the slip of the system. BYK-3760 is a…
