Silicone surface additive for solvent-borne coating systems with a medium reduction of surface tension and a medium increase of surface slip.
Solution of a polyether-modified polydimethylsiloxane
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.
- Anti-blocking Agents > Silicones / Silicas / Siloxanes
- Flow / Levelling Agents > Silicones
- Slip Control Agents > Silicones
- Surface Conditioners / Surface Modifiers > Gloss Control Agents
- Wetting Agents / Wet Edge Enhancers > Silicones
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.
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.
