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. Size: 200 gm, 1 kg, 5 kg & 20 kg Packs

Features

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

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

What sizes are available for Unibond SBR?

Unibond SBR is available in various sizes to meet different project needs, including 200 gm ,1 kg, 5 kg, and 20 kg packs.

How does Unibond SBR improve cement-based products?

Unibond SBR enhances the performance of cement-based products by improving adhesion, flexibility, and water resistance. It also increases the durability and strength of the final mix, making it ideal for applications requiring high-performance properties.

Can Unibond SBR be used with all types of cement-based products?

Yes, Unibond SBR is compatible with a wide range of cement-based products, including concrete, mortar, plaster, and screeds. It can be used in various applications such as waterproofing, bonding, and repair works.

What tips can help ensure proper installation of Unibond SBR?

Accurate Mixing: Always measure and mix Unibond SBR with water accurately to achieve the desired consistency and performance.
Clean Tools: Use clean tools and containers to avoid contamination that can affect the performance of the mix.
Surface Preparation: Thoroughly prepare the surface to ensure optimal adhesion and durability.
Application Consistency: Apply the cement slurry and plaster/mortar mix uniformly to prevent weak spots and ensure a strong bond.

How should Unibond SBR be stored before use?

Store Unibond SBR in its original, tightly sealed container in a cool, dry place. Protect it from freezing temperatures and direct sunlight to maintain its effectiveness and prolong its shelf life.

What are common mistakes to avoid when using Unibond SBR?

Incorrect Mixing Ratios: Using incorrect mixing ratios can lead to poor performance. Always follow the manufacturer’s recommended ratios.
Improper Surface Preparation: Failing to properly clean and prepare the surface can result in weak adhesion and reduced durability.
Using Contaminated Tools: Using dirty tools can introduce impurities that affect the quality of the mix.
Skipping Curing: Not allowing adequate curing time can compromise the strength and effectiveness of the applied mix.

Can Unibond SBR be used in all weather conditions?

While Unibond SBR can be used in various weather conditions, it is essential to avoid extreme temperatures, especially freezing conditions. In hot weather, ensure proper curing to prevent rapid drying and cracking.
