SBA PC – 50
ACRYLIC POLYMER ADDITIVE & BONDING AGENT FOR CEMENT SYSTEM
INTRODUCTION:

SBA PC -50 is an emulsion of an Acrylic Co-polymer.

SBA PC -50 is an additive for modifying cement mortar /concrete which improves the properties of cementitious compositions. It improves bond strength, mechanical properties & abrasion resistance of cement concrete / mortar. Thin sections dry rapidly and exhibit good adhesion to old concrete & masonry, brick, wood, metals & many other surfaces. SBA PC -50 modified mortars are uniform in colour & resist discolouration due to exposure to sunlight.

Addition of SBA PC -50 to cement mortar helps in retaining the water needed for hydration, as it forms a film of coalesced polymer sphere around sand and cement particles. This acts as a barrier to prevent further evaporation. SBA PC -50 acts as an internal curing membrance, thus eliminating any need for further curing with water.

SBA PC -50 conforms to ASTM 1069-86.
