Title:
The dry blended cement combination thing containing acrylic RDP and them containing a carboxyl group
Document Type and Number:
Japanese Patent JP6089048
Kind Code:
B2
Abstract:
The present invention provides water redispersible polymer powder (RDP) compositions that perform well even when redispersibility is fair comprising carboxyl group containing multi-stage acrylic copolymers having an alkali-soluble resin outer stage and one or more inner stage acrylic (co)polymer having a glass transition temperature (Tg) of from −40 to 50° C., one or more nucleating agent having a boiling point of 150° C. to 500° C., and a water solubility of 3.5% or less, preferably, an alkyl isobutyrate and a branched alkyl isobutyrate, and one or more colloidal stabilizer. Also provided are dry mix cement tile adhesive compositions comprising the water redispersible polymer powder an ordinary Portland cement, an alumina rich cement with an alumina content of from 30 wt. % to 85 wt. %, and calcium sulfate. The invention enables a broad range of the claimed acrylic polymers in useful RDPs.
