PC-Conbond® SBR

Styrene Butadiene rubber-based multipurpose product designed for waterproofing, bond coats, and concrete repairs

PC-Conbond® SBR is a premium synthetic styrene-butadiene rubber (SBR) based multipurpose polymer designed for high performance applications such as waterproofing and concrete repairs. It serves as an effective bond-coat for establishing adhesion between new and existing concrete surfaces. When incorporated into plasters, it enhances the workability of concrete and renders surfaces impermeable to liquids. Its exceptional characteristics make it a suitable choice for DIY waterproofing projects in areas like toilets, bathrooms, plastered masonry, and external walls.

FEATURES AND BENEFITS

  • This versatile polymer enhances the flexibility, elasticity, and tensile strength of cement, effectively mitigating cracks in mortars and cement screeds.
  • It establishes a robust bond with various cementitious substrates like concrete, plasters, masonry, and stonework.
  • This cost-effective and user-friendly waterproofing solution can be seamlessly applied to diverse substrates by blending it with cement.
  • To reinforce waterproofing, a 45 GSM glass fiber mesh can be inserted between the initial and subsequent coats.
  • By reducing the water cement ratio, it minimizes permeability, elevates water repellency, and bolsters the flexural strength of concrete, consequently reducing shrinkage cracks.
  • It also elevates the substrate’s hardness, enhancing abrasion resistance, and reducing dust generation when integrated into floor screeds.

USE

  • Concrete Repair: This encompasses the restoration of spalled concrete, floors, columns, beams, chugs, and precast segments.
  • Formulation of polymer-modified mortars: This is achieved by integrating PC-Conbond® SBR into sand-cement mixtures.
  • Waterproofing services: cater to submerged areas like bathroom slabs, chakras, balconies, terraces up to 750 sq ft, retaining walls, and water tanks.
  • It serves as a bonding agent for securing new concrete to existing concrete surfaces.
  • It functions as a polymer modifier for floor screeds.
