RayKote® 444S
Styrene Acrylic Emulsion
RayKote 444S is a styrene acrylic emulsion designed for blending with cement for flexible concrete and crack resistant stucco. Specifically designed as a polymer modifier for cement, it exhibits excellent compressive strength and crack resistance. Its high alkalinity allows compatibility with “green” cement to yield flexible concrete patches and overlays.
Key Features
- Superior compressive and flexural strength
- Excellent crack resistance
- Outstanding adhesion to old concrete and masonry surfaces
