How can I improve the defoaming and flowability properties of my 3K epoxy grouting formulation?

the flow properties of the system. Applied on the powder components, the latter can also help to de-dust the product. For further information please refer to…

My mold release agent has difficulties to stick onto hot metal surfaces due to the Leidenfrost effect. How can I improve…

The primary wax emulsions HORDAMER do not show the Leidenfrost effect. HORDAMER PE 02 and HORDAMER PE 03 show excellent wetting onto hot metal surfaces. Due to…

I have noticed that the laser welding of the plastic components we use has variances despite very closed monitored laser…

discuss the matter with the manufacturer of your master batches. The manufacturer can achieve better distributive qualities of the laser additives in the master…

Which rheology additives can be used in a waterbased polyurethane formulation to create a good flow behaviour by using a…

adjusted rheology profile. A combination of RHEOBYK-H 3300 VF and RHEOBYK-L 1400 VF can provide this requirements without creating negative side effects.

Can you recommend any additives to prevent settling of inorganic and metal pigments?

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…

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 developing 2 pack polyurethane coatings. Sometimes, the cured coating shows flooding and floating. The problem is…

Organic pigments like phthalocyanine blue, phthalocyanine green and carbon black are the most difficult pigments to be wetted, dispersed and stabilized. One…

I want to improve the wetting properties of my oil based lubricant onto metals. Can I reduce the surface tension?

The addition of silicone surface additive will reduce the surface tension of the oil and improve the wetting onto metals. You should try 0.2% BYK-310 and…

I am working on an epoxy system, which is highly filled and I run into the following issue: It it very high viscous, but…

To improve the flow we advice to use a viscosity reducing wetting and dispersing additive. DISPERBYK-142 or BYK-9076 are our first recommendations when it comes…

Our target is to formulate a Polayaspartics top coat, which has a smooth, dull surface. How can we achieve this?

It is a little bit difficult to matt a Polyaspartics coating. Due to the low VOC content, the shrinkage of the coating is very limited. This shrinkage is very…

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

excellent mechanical properties. Air release additives, like BYK-1786 or BYK-028 can help to improve these properties by improving the deaeration of the system…

Which additive can be used as leveling additive for polyaspartic-based floor coating formulations to improve the surface…

BYK-327 is a silicone containing surface additive, which provides a balance between excellent leveling properties and additional defoaming effect.
