Leveling Agent and Flow Promoter for Solvent-Based Paints and Coatings

Borchi® Gol PL is a phenylmethyl polysiloxane leveling agent and flow promoter for solvent-based coating systems. This VOC-free solution effectively eliminates surface defects and is 100 % active.


Benefits of Leveling Agents and Flow Promoters

Borchi® Gol PL promotes good flow and leveling properties in paints and coatings by significantly reducing surface tension. This solution allows coatings to achieve a smooth, even finish before it cures.

Borchi® Gol PL prevents leveling issues in paints and coatings


Borchi® Gol PL inhibits the formation of surface defects like orange peel and craters.

Orange peel is the inability of a coating to overcome varying surface tension issues because of varying film thicknesses, rapid solvent evaporation, and/or coating incompatibility.

Flow and leveling properties in Borchi® Gol PL resolve orange peel issues in coatings.


Solvent evaporation leaves behind a very viscous film which effectively freezes defects in place. These small indentations, or craters, can be caused by poorly dispersed defoamers or contaminants caught in the film like dust or dirt.


eliminate crater formation in paints and coatings



Borchi® Gol PL helps overcome the surface tension around these particles to form a smooth finish before the film solidifies.



Coating applications for Borchi® Gol PL include can and coil coatings. This solution is ideal for paraffin-free polyester resin systems, epoxy resins, and combinations of epoxy resins with phenolics or amino resins. It is compatible with numerous organic binders. Borchi® Gol PL works well in non- and medium-polar systems.
