SBS Reinforced Bitumen – Technical Description, Properties, and Applications

Iso Polymer Bitumen is a high-performance waterproofing and insulation material manufactured from penetration grade bitumen 60/70, reinforced with SBS (Styrene-Butadiene-Styrene) polymer. The polymer modification significantly enhances the elasticity, adhesion, and durability of the base bitumen, making it suitable for demanding construction and insulation applications.

This product forms a seamless, elastic, and long-lasting protective layer after application, effectively preventing the penetration of water, moisture, and humidity across a wide range of building surfaces.

Material Characteristics and Performance

Iso Polymer Bitumen combines the thermoplastic behavior of bitumen with the elastic properties of SBS polymer, resulting in a material that:

• Maintains flexibility under temperature fluctuations

• Exhibits excellent adhesion to most construction substrates

• Resists cracking caused by structural movement

• Provides continuous waterproofing without joints or overlaps

Once cured, the coating remains elastic and capable of accommodating minor substrate movements without loss of performance.

Reinforcement by SBS Polymer

The SBS polymer reinforcement provides:

• High elongation and elastic recovery

• Improved resistance to aging and environmental exposure

• Enhanced bonding strength to concrete, metal, and masonry surfaces

• Increased durability against mechanical stress and micro-cracking

This makes Iso Polymer Bitumen especially effective for long-term insulation systems.

Applications of Iso Polymer Bitumen

Iso Polymer Bitumen is widely used for waterproofing and insulation of:

• Building surfaces: interior and exterior walls, ceilings, and floors

• Wet areas: kitchens, bathrooms, sanitary units, and utility spaces

• Concrete foundations: basements, footings, and structural slabs

• Metal surfaces: corrosion protection for exposed steel components

Additional practical applications include:

• Sealing and covering expansion joints in concrete structures

• Asphalt sealing for roads, sidewalks, and pavements

• Restoration and repair of existing bitumen-based insulation systems

Advantages of Iso Polymer Bitumen

Key benefits include:

• High adhesive strength on various substrates

• Exceptional elasticity to absorb building movements and cracks

• Strong resistance to harsh environmental and climatic conditions

• Self-recovery capability for minor physical damage

• High chemical resistance to sulfates, chlorides, acids, and alkalis

• Seamless waterproofing without joints, overlaps, or welding

Application Method

Iso Polymer Bitumen can be applied using two methods:

Cold Application:

• Dilute the product with the required amount of water to achieve the desired consistency

• Apply using brush, roller, or suitable spraying equipment

Warm Application:

• Heat the product until it becomes fully molten

• Apply evenly to clean and dry surfaces

In both methods, the substrate must be clean, dry, and free from dust, oil, and loose particles to ensure optimal adhesion.

Handling and Packaging

Iso Polymer Bitumen is easy to handle and suitable for both cold and warm applications. It is supplied in:

• 15 kg cartons or containers

• 170-liter steel drums

These packaging options allow flexibility for small-scale and large-scale projects.
