BYK-325 N

Coatings Industry
Special Features and Benefits
The additive causes only a slight reduction in the surface tension of the coating systems and improves the leveling in the coating layer used. BYK-325 N prevents the show-through of cleaning traces (wiping marks) if the coating is recoated. In order to prevent this defect (also called “ghosting”), the additive must be used in the coating layer
that is to be recoated.
Recommended Use
The additive is recommended for all solvent-borne coatings.
Recommended Levels
0.05-0.6% additive (as supplied) based on the total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
The additive can be incorporated at any stage of the production process, including post-addition, as long as homogeneous incorporation in the system is ensured.
Special Note
Unlike so-called silicone oils, this additive is very user-friendly. However, before use, one should determine in a test series whether the foam is stabilized in certain systems. Similarly, recoatability and cratering should be investigated.

BYK-325 N is the butyrolactone-free version of BYK-325. The active substance and active substance content are the same as BYK-325.

The product may solidify below 15 °C. Warm to <50 °C and mix well.
