Typical properties：
appearance：amber-colored clear liquid
Active matter content：100％.
Refractive index at 25oC：1.444-1.451
Viscosity at 25C：1000-2000cp

Special properties：
Provides strong slip, scratch resistance and anti-blocking.
Excellent leveling and anti-crater performance.
As a surfactant in many applications including polyurethane foams and coatings

Dosage (additive as supplied):
Silibase-2819A Silicone Additive can be used as an additive in coatings to provide slip and mar resistance (typically 0.1-1.0% by weight), for preparing flexible PU foam (typically 0.5-2 parts surfactant per 100 parts polyol), and for compatibilizing MDI with water (typically recommended loading 60 parts MDI/water per 1 part Silibase-2819A Silicone Additive). It is the user’s responsibility to determine the optimum surfactant loading for the particular formulation.

Package and storage stability：
Available in 25 liter pail and 200 liter drums.
24 months in closed containers.
