WATER RESISTANT STYRENE BUTADIENE BONDING AGENT
HIGHBOND SBR is a high performance, non redispersible, Styrene Butadiene Rubber latex designed bonding agent and multipurpose admixture for cementitious systems which enhances water and abrasion resistance and increase durability. HIGH BOND SBR Waterproof Bonding Agent is ideal for use in internal and external renderings, flooring screeds and patch repairs. It can be used internally or externally where improvements in the physical properties of Portland cements systems are required.
Features
- Increases durability and flexibility
- Ensures bonding of floor toppings, renders and repairs
- Reduces shrinkage and cracking
- Increased durability and toughness.
- High resistance to water penetration.
- Good abrasion resistance and proven performance
- Good resistance to many chemicals, frost, salt and to mineral oil.
- Excellent adhesion to steel and concrete.
- Adheres well to brick, glass, asphalt, wood, expanded polystyrene etc
- Prolonged corrosion protection.
- Similar thermal expansion and modulus
- Properties to concrete (unlike resin mortars and primers).
- Non-toxic. Can be used with potable water
Application
Hot, exposed or very absorbent surfaces should bed dampened prior to application or priming with a mix of 1:8 bond and water. Washed aggregate and sand particle sizes should also correspond to the thickness of mortar to be applied and the required surface finish. SBR is compatible with manual mixing or misers of rotating blades. Agitation should be minimized to maintain good densities and avoid penetration of air. For better effects all applications other than those sprayed on renders, a bonding primer
coat 1:1 (HIGHBOND SBR : Water) is recommended. This can be brushed into the prepared surface and fresh mortar should be applied while the bonding coat is still wet. If it is water resisting renders please ensure that two priming coats are applied at right angles to a minimum and normal thickness of 1.5mm
