Nitobond SBR
Nitobond SBR is modified styrene butadiene rubber emulsion
specially designed for use as a bonding aid and gauging liquid
for cementitious systems. It is resistant to hydrolysis and can
therefore be used for external applications too.
Uses
For modifying and improving bonding of fl oor toppings, ren-
derings and mortars; repair of worn, damaged and spalled concrete, repair of large cracks; polymer modified floor screeds;
waterproof plasters for masonary and slurries.
Advantages
- Simple to use - Single component, gauged as required.
- Versatile - Compatible with all common hydraulic cements.
- High adhesion - Provides excellent bond to concrete, adhesion plaster, masonry, stone work, etc.
- Reduces permeability- Provides waterproof screeds, plasters and permeability slurries.
- Cost effective - Nitobond SBR is economical to use
- Increases strength - Improved tensile and flexural properties allow thin applications.
- Improves durability -Gives weather resistant mortar with improved impermeability to chlorides and other harmful agents.
