Sovereign SBR Bonding Agent is a dispersion polymer of carboxylated styrene butadiene copolymer. It has been extensively used in the building industry for many years in the modification of cementitious systems, such as mortars, render, screeds, for example.
Unlike PVA when used in damp areas Sovereign SBR Bonding Agent will not re-emulsify and should therefore be specified for all external situations.
Sovereign SBR Bonding Agent contains antifoam to help prevent excessive air entrainment and an antioxidant to give extended durability.
Form Supplied: Milky white liquid
Packaging: 10 kg
Contains: 47% styrene butadiene
Coverage Rate: Please see Technical Datasheet
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 ahesion to the substrate, reduced cracking and surface dusting. Furthermore, resistance to water and the passage of salts is greatly improved making it ideal for external use.
Sovereign 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 Sovereign SBR Bonding Agent greatly enhances the resistance of the concrete to carbonation and protects steel from corrosion. It's use in screeds allows work to be carried out in much thinner sections whilst maintaining peformance levels.
