Fosroc Nitobond SBR Latex 20ltr

Fosroc Nitobond SBR Latex 20ltr Latex based Mortar and screed modifier & bonding agent, For modifying and improving bonding of floor toppings, renderings and mortars; repair of worn, damaged and spalled concrete, repair of large cracks; polymer modified floor screeds; waterproof plasters for masonry and slurries.

Description:
Nitobond SBR(Latex) is modified styrene butadiene 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.

Chemical resistance:
Cementitious materials have limited chemical resitance. The addition of Nitobond SBR (Latex) to cement mortars reduces permeability and therefore helps reduce the rate of attack by aggressive chemicals.

Typical Mix designs :

1. Patching and repair mortars and plaster for masonary:

Cement                                           50 kg
Zone II sand                                  150 kg
Nitobond SBR (Latex)                 5 – 9 litres
Recommended water addition  11 – 15 litres
Recommended thickness           8 to 30mm

2. Heavy duty floor screeds:

Cement                                          50 kg
3-6mm Granite chips                 75 kg
Zone II sand                                 75 kg
Nitobond SBR (Latex)                5-9 litres
Recommended water addition 8 – 12 litres
Recommended thickness          10-25mm

The screed should be of a semi-dry cohesive consistency.

3. Polymer modifi ed cement grout for injection – Nitobond SBR (Latex) can be used to eff ectively modify properties of cement grout for crack injection. The dosage of Nitobond SBR(Latex) shall be in the range of 3 L/bag of cement. The injection is carried out as per standard practice.

Packaging:
Nitobond SBR (Latex) is supplied in 5, 20 & 50 litre containers.

Coverage:
Slurry primer – approximately 4- 5 m2/ litre depending on substrate porosity.

Shelf life:
Nitobond SBR (Latex) has a shelf life of 12 months if kept in a dry store in unopened condition.

Additional information:
Nitobond SBR (Latex) is part of a wide range of adhesives, repair mortars, sealing compounds and flooring products specially designed and manufactured by Fosroc for the construction industry. Separate datasheets are available on all these products.
