Latest Patents

Kühn holds a patent for "Redispersible polymer powder compositions prepared from styrene butadiene-based latex for dry mix formulations." This patent describes a composition that includes a polyglycol mixed with a redispersible polymer powder (RDP). The RDP consists of a codried mixture of a carboxylated, water-insoluble film-forming styrene butadiene polymer and a colloidal stabilizer. This composition results in cement formulations that exhibit superior bonding strength and adhesion after water immersion. The inclusion of polyglycol enhances workability during application, while the RDP composition improves abrasion resistance, surface appearance, and color. Notably, it allows for a significant reduction in the amount of retarder used in dry mix formulations for cement compositions.
