5 Outstanding Benefits

Rheology control
Maintains stable viscosity and flow

Sagging Prevention
Prevents sagging on vertical surfaces.

Anti-settling
Keeps pigments well-dispersed, avoids sedimentation.

Improved hardness
Enhances film strength and scratch resistance

Corrosion resistance
Protects against moisture and chemicals.

Low-BET Rice Husk Silica for Paints & Coatings
BY-O-COAT RC 300A is a bio-based, hydrophilic silica derived from rice husk, specifically engineered with low BET surface area. It functions as an effective rheology control additive for paints and coatings, offering excellent viscosity stability, anti-settling properties, and improved application performance across a wide range of formulations.
