Properties of polymer-modified mortars using epoxy and ...

Feb 01, 2007  Moreover, epoxy emulsion is considered non re-emulsifiable latex and therefore it should not destabilise under humid and alkaline environment, but acrylic based mortar can. Thus, polymer modified cementitious mortars based on epoxy emulsion shall be more suitable for use in structures exposed to high humid conditions or immersed in water.
