Water-based elastomeric coatings are used for different purposes including roof coatings, waterproofing and sound deadening.
These waterborne systems are typically based on either acrylics or synthetic rubber dispersions. Their common purpose is to protect the underlying material typically from attrition by water, UV radiation, chemicals and wear.
General challenges related to the formulation of elastomeric waterproofing coatings with traditional thickeners are related to water sensitivity, applicability, flow and levelling, sprayability and sagging, storage stability, as well as mud cracking.
Addition of Borregaard biopolymers into the formulation improves the general stability, increases the tensile strength of the elastomeric coatings without sacrificing the elongation as well as allows you to apply thicker layers without fear of sagging nor mud carking. They will also reduce the water absorption of the coating significantly.
Our products offer the following benefits for elastomeric coatings
- Improved strength
- Mud-crack resistance
- Improved open-time
- Reduced tackiness
- Reduced water absorption
