24-88S
24-88S polyvinyl alcohol, which is quickly soluble in cold water, can provide high viscosity and certain filming property for slurries. It improves flexibility, water retention and workability of cenment, lime or calcium carbonate based mortars if used in combination with water retaining agent such as cellulose ether. 24-88S is also an important raw material for building glue.
