SBR bonding agent and mortar admixture

UniBond 865 is a styrene butadiene rubber latex (SBR). It is specially formulated to be used as a bonding agent and admixture for cement-based mixes.
Features and benefits

• Non-toxic. Ideal for use in contact with potable water.
• Improves waterproofing, durability, flexibility, cohesion & workability and reduces shrinkage.
• Excellent bonding properties to steel reinforcement, concrete, masonry and most construction materials.
• Suitable for internal, external and submerged applications.
• Improves all physical characteristics of cement-based mixes.
• Good resistance to many chemicals.
• Modified mortars with UniBond 865 have similar thermal expansion and modulus properties to concrete (unlike resin mortars and primers).

Cement-based renders/mortars can be used in the following applications:

• Bonding new concrete to old when used as a slurry coat.
• Concrete repair mortars. Suitable to repair spalled concrete and damaged concrete floors.
• Thrown coat and base coat weather proof renders.
• Tile adhesives mortar.
• Waterproof renders. Ideal for basements, swimming pools and water tanks.
• Floor screeds. Produces abrasion resistant and non-dusting floors, underlay for special finishes are required.

Modified mixes may be slightly darker than the corresponding unmodified mixes.
