Sovereign SBR Bonding Agent
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.
Unlike PVA when used in damp areas, 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.
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. Furthermore, resistance to water and the passage of salts is greatly improved 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 Sovereign SBR Bonding Agent greatly enhances the resistance of the concrete to carbonation and protects steel from corrosion. Its use in screeds allows work to be carried out in much thinner sections whilst maintaining performance levels.
Incorporating SBR Bonding Agent into cement-based systems gives numerous advantages, chiefly among these are:
- Greatly improved adhesion to a wide range of substrates including dense concrete, glass, steel, tiles, etc.
- Mixes may be applied in much thinner sections.
- Excellent resistance to water and protection from carbonation.
- A high level of resistance to salt permeation.
- Much improved toughness and flexibility.
