MagicShield - Unibond (SBR) is a modified styrene-butadiene liquid emulsion that works as a ready-to-use bonding agent for repairing spalled concrete floors, columns, beams, and slabs. Its bonding capabilities also work well when bonding old concrete and mortar to new layers of concrete and mortar.
In addition to this, MagicShield also works great as a waterproofing agent for bathrooms, roofs, underground concrete tanks, walkways, and small terraces by providing a damp-resistant, anti-carbonation coating to the structures. Other use areas for UWB are:
Packaging Size: 200 gm, 1 kg, 5 kg & 20 kg packs.
UWB has a first of its kind built in, intrinsic corrosion inhibitor technology which aids in it becoming resistant to erosion and corrosion
It is a multipurpose product that has a straightforward application method and is cost-effective
Enhances the durability and strength aspects of the cementitious system, enabling it to be applied in thin, refined layers.
Averts crack formation by enhancing its ability to bend, hence increases flexural strength. It furthermore curtails shrinkage cracks related to drying and aging
Possesses exemplary bonding to concrete, masonry, stonework, plasters cementitious surfaces, asphalt and other building materials and components
Does not breakdown when it comes in contact with water molecules, hence it is immune to hydrolysis. Due to this quality, it can be used for external applications
It has increased resilient properties, while also increasing the toughness and hardness of cementitious film or mortar. It further prevents the generation of dust
Increases and enhances the ability of cement mix to withstand abrasion
It is used for reducing the viscosity of the pumpable cement injection used for grouting. It provides the grout with enhanced bonding and fluidity characteristics
It provides mortar with better endurance, and ability to prevent chlorides and other harmful substances from passing through
