POLYURETHANE POWDER BLEND WITH REDISPERSIBLE POLYMER POWDER FOR CEMENT COMPOSITIONS
Powdered polyurethane flexible foams, preferably powdered recycled polyurethane flexible foams are used with a redispersible polymer powder (RDP), preferably as a preblended additive, in hydraulic binders or cementitious compositions to improve performance of cementitious compositions or mortar, in applications such as cement based tile adhesives (CBTA), or external thermal insulating composite systems (ETICS). The use of the powdered polyurethane flexible foam as a partial replacement for an RDP unexpectedly provides an increase in wet mortar density while maintaining excellent workability and quick open time, quicker setting times, improved impact resistance, and increased adhesion after water immersion.
