5Ltr Alphachem SBR Bonding Agent

Description

SBR Bonding Agent 25 Litre

Product Description

SBR BOND is a white liquid, which has numerous uses as an admixture, primer, bonding agent and sealer.  

Polymer Emulsions of this type have been used extensively over the last 20 years by the building industry as an admixture for cement and concrete applications, including repair and renovation, surfacing of floors and bonding generally.  It contains anti-foam to control the density of cementitous mixes.

Benefits

• • Greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc.

• • Mixes may be applied in much thinner sections

• • Excellent resistance to water and water vapour

• • A high level of resistance to salt permeation

• • Much improved toughness and flexibility

• • Reduced surface dusting of concrete

• • Greatly improved resistance to many chemicals- ideal for use in dairy parlours etc.

• • Reduced water: cement ratio for equivalent workability

• • Improved frost resistance

• • SBR Bond is also freeze thaw stable.

Areas For Use

• • As an admixture for mortar/screeds/renders.

• • As a bonding agent for screeds/renders.

• • As a primer/sealer in tiling applications.

• • As a flexibliser for cementicious based tile adhesive when tiling on wooden/asphalt floors.

• • In addition, SBR Bond has the advantage over PVA bonding aids in that it is not adversely affected in wet conditions and is therefore recommended for exterior use.

Limitations

• • In common with other SBR products, SBR BOND is not suitable for coloured exterior decorative renders which will not be subsequently overpainted. Its poor UV resistance may cause discolouration

Surface Preparation

All surfaces must be clean, dry and free from dust, grease and other contaminents.

Application

SBR BOND – FLOORING APPLICATIONS

This concerns the use of SBR Bond in screeds and toppings over background concrete. Adding SBR Bond to a floor screed or topping gives the following advantages:

• • A low water:cement ratio allows a minimum of delay when overcoating is required.

• • Reduced permeability to liquids.

• • Improved chemical, abrasion and impact resistance .

• • Resistane to dusting.

• • Thinner screeds, achieving reduction in weight and savings in materials.

• • Excellent slip resistance.

• • Goods underlay for epoxy surfacing.

• • SBR Bond has a long and successful track record of use in the construction industry.
