Silicon Based Anti-stripping Additive
Nano-technology based Anti-stripping Additives are the latest innovation in asphalt road construction technology. Having the space age technology and acting as an adhesion promoter / water proofing agent, these additives utilize the bond formation at molecular level, so they are low dose products with ultimate thermal stability.
Our Nano-technology products work on synergistic combination of molecular amine and silicon acting as reactant as well as facilitator for active bridge formation between road aggregates and bitumen. The bond formation by these additives are very stable and provide a very long water protection for the treated surface.
Mode of action :
- Nano-technology based Anti-stripping Additives are based on silicon and amine molecular chemistry. These products assist in formation of a non-reversible covalent bond between bitumen and silica present in road aggregates. Since this bonding is at molecular level, it is one of the toughest in present day chemistry, which is resistant to the action of higher temperatures or water.
- When these innovative Nano-technology products are mixed with bitumen, the polyamine groups react with organic acids present in bitumen and create a basic environment beneficial for stronger bitumen-aggregate bond formation and molecular reactive silicon forms complex silicon bridge intermediates.
- When the Nano-technology anti-stripping additive treated bitumen is mixed with common road aggregates, the active silicon bridge intermediates in bitumen readily form covalent bond with nearest silicon molecules on aggregate surface. This bond is physically and chemically resistant so it does not allow ingress of water between bitumen-aggregate interfaces.
- Since the active silicon bridge formation takes place at molecular (Nano) level, a small dose of these products are enough to achieve complete protection from water damage.

"Wetbond-S" is next generation Nano-technology Silicon based Anti-stripping Additive for Asphalt. This product is a low dose and extremely thermal resistive additive for use in Hot-mix and Warm-mix road constructions. This product is specially suitable for aggregates having very high and tough to control stripping profile.
Physical Properties :
"Wetbond-S" is brownish clear liquid at room temperature with characteristic citrous odour. This product is non-miscible with water and miscible with polar & hydrocarbon solvents. The thermal stability of this product in hot bitumen (at 160°C) is over 15 days and no additional dose addition/adjustment is required on prolonged storage in hot bitumen in normal course of Hot-mix and Warm-mix pavement constructions. As this product is used in a very low dose, it does not have any effect on physical properties of paving bitumen of any grade including VG-10, VG-30, VG-40, CRMB or PMB (Elastomeric & Plastomeric types) towards Penetration, Softening Point, Ductility etc. However the chemical properties are changed tremendously as the bitumen becomes more receptive to aggregates and bonding between aggregates and treated bitumen becomes highly resistant to stripping even under extreme atmospheric conditions. This ensures long term pavement durability without affecting the quality of work. This product is suitable for production of Refinery-treated non-stripping bitumen, Hot-mix pavement constructions, Warm-mix constructions and for industrial bituminous coatings.
Chemical properties :
- Dose: 0.04 to 0.07% by weight of Bitumen ( 0.4 to 0.7 Kg per MT of Bitumen)
- Specific Gravity : 0.86 - 0.95
- Amine Value: > 200
- Active Nitrogen : > 7.00
- Water Content : < 1.0%
- Active content : 100%
- Shelf Life : 4 Years from the date of production in sealed containers.
- Colour : Brownish clear liquid.
- Compatibility : All grades of Road and Industrial Bitumen.
Advantages :
"Wetbond-S" is oily liquid product for premixing or direct injection in Bitumen. This product has several advantages over conventional Anti-stripping Agents:
- Very low dose product, no effect on bitumen properties.
- No degradation when stored in hot bitumen, saves money.
- Nano active amine and silicon based, works on molecular level.
- High amine value for active bridge formation between Bitumen and aggregates.
- High Nitrogen content gives excellent performance even with moist aggregates.
- Readily soluble in hot bitumen, so fit even for direct dosing in HMP.
- Non Hazardous product for safe handling and storage.
- Economical as compared to conventional products in dose dependent comparison.
Storage and Handling :
"Wetbond-S" can be stored in HDPE or MS drums / tanks at a cool and dry place at ambient temperature. This product contains organic silicon derivatives which can cause mild irritation to skin, eyes and lungs.
