Unibond SBR

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, Magicrete Unibond SBR 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:

-It can be used as an additive in injection grouting for cracks and fissures

-It works as a great anti-corrosive coating on steel structures

-Ensures long-lasting and waterproof coating when used with cement paint

-Reduces shrinkage resulting in the prevention of cracking, dust build-up,

and improvement in abrasion resistance

-It works as a great bonding agent for tiles and panels

-As a top finishing for chemical resistant floors

-Is a great fixing agent for slip bricks, tiles, and marble bedding

Suitable For: Waterproofing underground/overhead concrete tanks,

toilets, bathrooms, roofs. Also for repairing spalled concrete floors,

columns, beams, slabs & cracks in masonry.

Packaging Size: 200 gm, 1 kg, 5 kg & 20 kg packs.

Features & Benefits

Anti- Erosion/Corrosion

UWB has a first of its kind built in, intrinsic corrosion inhibitor technology which aids in it becoming resistant to erosion and corrosion

Multipurpose and Cost-effective

It is a multipurpose product that has a straightforward application method and is cost-effective

Durable

Enhances the durability and strength aspects of the cementitious system, enabling it to be applied in thin, refined layers.

Non-Crack Forming

Averts crack formation by enhancing its ability to bend, hence increases flexural strength. It furthermore curtails shrinkage cracks related to drying and aging

Excellent Bonding

Possesses exemplary bonding to concrete, masonry, stonework, plasters cementitious surfaces, asphalt and other building materials and components

Anti-Hydrolysis Agent

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

Tough/ Resilient

It has increased resilient properties, while also increasing the toughness and hardness of cementitious film or mortar. It further prevents the generation of dust

Abrasion Resistant

Increases and enhances the ability of cement mix to withstand abrasion

Grouting

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

Weather Resistant

It provides mortar with better endurance, and ability to prevent chlorides and other harmful substances from passing through
