C-21 ALL ACRYLIC
Silpro’s C-21 All Acrylic is a 100% acrylic latex used as an admix or internal bonding agent, or primer. This is a water-based cement modifier admix/internal boding agent that enhances the performance properties of the cementitious mortars and coatings.
When you add it to the mix, it forms a plastic matrix or film, that helps retain water and promotes cement hydration, resulting in improved compression without wet curing.
C-21 gives portland cement and gypsum mixes greatly improved tensile and flexural strength, flexibility, and maximum adhesion to old or new concrete surfaces for patching, grouting or coating.
C-21 All Acrylic is available in 1 gallon jugs or 5 gallon pails.
