Special Note
  • Unlike so-called silicone oils, this additive is very user-friendly.
  • However, before use, one should determine in test series whether foam is stabilized in certain systems and check the recoatability and crater development.

Special Features and Benefits
The additive provides a medium reduction of surface tension in the coating systems. It increases slip and improves leveling and gloss. Silicone additives prevent the formation of Bénard cells. BYK-300 also improves substrate wetting and anti-blocking properties.
Recommended Use
BYK-300 is broadly compatible and suitable for all solvent-borne systems.
Recommended Levels
0.1-0.3% additive (as supplied) based upon 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 during any stage of the production process, including post-addition. Thinning before incorporation may make dosing easier.
Special Note
Unlike so-called silicone oils, this additive is very user-friendly. However, before use, one should determine in test series whether foam is stabilized in certain systems and check the recoatability and crater development.
