Sovereign SBR Bonding Agent

SBR Bonding Agent is an additive for improving the adhesion, flexibility, and water resistance of cementitious mixtures, mortars and concrete. Unlike PVA, when used in damp areas, this bonding agent will not re-emulsify and should be specified for all external situations. SBR Bonding Agent contains anti-foam to help prevent excessive air entrainment and an antioxidant to give extended durability. It can be used in both, renders and floor screeds, and is an integral part of the Hey’di K11 tanking system. Renders and screeds show greatly improved adhesion to the substrate, reduced cracking and surface dusting. The additive greatly improves resistance to water and the passage of salts, making it ideal for external use. SBR Bonding Agent can also be used as a primer and sealer to improve inter-coat adhesion between successive layers. When used in concrete repair, the addition of the SBR Bonding Agent greatly enhances the resistance of the concrete to carbonation and protects the steel from corrosion. Its use in screeds allows work to be carried out in much thinner sections whilst maintaining performance levels.
