VISCOBYK 4015 is a medium to highly volatile viscosity reducer additive that is particularly suitable for unfilled and low filled systems. VISCOBYK 4015 reduces the viscosity allowing for improved flow and leveling properties. It has a low density and solidification point making it well-suited for applications requiring precise thickness control and uniform coverage. VISCOBYK 4015's volatility helps release entrapped air for a smooth surface finish. Its properties allow for enhanced material handling and application characteristics. VISCOBYK 4015 is recommended for formulations where low viscosity and air release are important for optimized performance.
