Polymer anti cracking waterproof mortar is a powdered product made by mixing high-grade ordinary silicon cement, high-quality quartz sand, imported rubber powder, and various functional additives and admixtures. Polymers can be homopolymers formed by polymerizing one monomer, or copolymers formed by polymerizing two or more monomers. The polymer must form a film under environmental conditions to cover the cement particles and form a strong bond between the cement body and the aggregate. Polymer networks must have the ability to prevent microcracks from occurring and to prevent the propagation of cracks.
