Surface Tension Modifier

Borchi® Gol 1473 is a polyether modified polysiloxane surface tension modifier for improved flow and leveling properties and surface smoothness. This flow and leveling agent is VOC-free and works in solvent-based, solvent-free, and water-based coatings systems.


Benefits of Surface Tension Modifiers

Surface tension modifiers like Borchi® Gol 1473 improve slip, flow, and leveling in a variety of coating systems. They act as substrate wetting agents to reduce the surface tension of the liquid.

This additive provides superior surface smoothness by preventing the formation of fish eyes, craters, and pinholes. Borchi® Gol 1473 reduces orange peel, which indicates that an unattractive wavy pattern is visible in the paint. Haze is lowered and the Distinctness of Image (DOI) is improved with the use of this flow and leveling agent. These qualities indicate that coated surfaces are very reflective, which is ideal for high gloss coatings.


Borchi® Gol 1473 contains properties that provide reflective surfaces and prevent surface defects for coating formulations


Borchi® Gol 1473 is stable in water regardless of the pH level.



Borchi® Gol 1473 is recommended for top coats that are cured at room temperature and below 150 °C in solvent- and water-based systems. This solution can also be used in solvent-free systems. Borchi® Gol 1473 can be used in a variety of binders.
