Nitobond SBR Latex Price in Bangladesh

Description

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.

Uses:
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.

Advantages:

•  Simple to use – Single component, gauged as required.
• High – Provides excellent bond to concrete, adhesion plaster, masonry, stone work, etc.
•  Improves -Gives weather resistant mortar with improved durability impermeability to chlorides

and other harmful agents.

•  Reduces – Provides waterproof screeds, plasters and Permeability slurries.
•  Increases – Improved tensile and flexural properties strength allow thin applications.
•  Versatile – Compatible with all common hydraulic cements.
•  Cost effective – Nitobond SBR (Latex) is economical to use

Properties:
Typical mechanical properties of 1 : 3 cement sand mortar at W/C – 0.45 for control and W/C – 0.35 for mortar containing
Nitobond SBR (Latex) ( 5 lites / 50 kg cement ). Tested in accordance with BS 6319 & wet cured. Specific Gravity 1.015 to 1.040 @ 27OC Mechanical properties Control Nitobond SBR (Latex)

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

Application instructions
Surface Preparation
The object of the surface preparation is to achieve a clean sound surface with a good mechanical key. All substrates
should be cleaned and free of dust, plaster, oil, paint, grease, corrosion deposits, and any other deleterious substances.
Laitance should be removed by mechanical means. Smooth substrates must be mechanically roughened e.g. by scabbling, needle gun or grit blasting to provide an adequate key. Corroded reinforcing steel should be exposed around its full circumference and cleaned to remove all loose scale and corrosion deposits. It is always preferably to clean the steel to a bright condition. Use of emery cloth, grit or sand blasting is recommended.

Priming:
Reinforcing steel must be primed with Nitozinc Primer immediately after cleaning. The concrete substrate should be
thoroughly dampened with water and any excess removed before being primed by thoroughly scrubbing in a slurry coat of 1 volume Nitbond SBR (Latex) to 1 volume water to 3 volumes fresh cement. In order to obtain a smooth consistency, the cement should be blended slowly into the liquids. Stir frequently during use to offset settlement. Avoid ‘puddling’ of the slurry coat. The topping must be applied on to the wet slurry. If the slurry dries out it must be removed, and the clean substrate reprimed.

Cleaning:
Tools and equipment should be washed with water immediately after use.

Additional Guidance:
Prepare surfaces thoroughly. Toe-in at edges wherever possible to avoid feather edging. All surfaces including edges must be primed. All applications should be wet on wet, the primer must not be allowed to dry. The level of added water in the mix designs may need adjusting to achieve the required consistency. In general water content should be kept to the minimum necessary. For consistent performance the use of clean, dry sand is recommended. Where wet sand is used, reduce the added water level as appropriate.

In order to prevent rapid drying, mortars should be properly cured with Concure WB, curing compound. Protect uncured mortar from frost. Do not retemper mortar or primer after initial set. Minimum application temperature is 100 C. For permanently immersed conditions consult Local Fosroc office.
