SikaBond® SBR 5L is a versatile styrene-butadiene bonding agent, primer, and admixture designed to improve adhesion, strength, and water resistance in cement and concrete applications
SikaBond® SBR 5 L
SikaBond® SBR is a high-performance styrene-butadiene copolymer designed for use as a bonding agent, primer, waterproofing additive, and mortar admixture. Ideal for areas exposed to moisture and water, it enhances the performance of cement-based mixes by forming a durable reinforcing polymer that improves adhesion, flexibility, and long-term durability.
Suitable for a wide range of construction, repair, and renovation applications, SikaBond® SBR significantly improves water resistance and reduces permeability, making it especially effective for rendering, screeds, and flooring systems. Its anti-foam formulation ensures optimal mix density, while its compatibility with a range of building materials ensures dependable performance across multiple substrates.
