What Are Antistripping Agents?
Antistripping agents are specialized chemical additives used in asphalt mixtures to enhance the adhesion between bitumen (asphalt binder) and mineral aggregates. Over time, moisture and traffic can cause bitumen to lose its grip on the aggregate, resulting in a process known as 'stripping' — a key factor in pavement failure.
These agents act as adhesion promoters by forming a stronger chemical bond between bitumen and aggregate surfaces. This significantly improves the moisture resistance of asphalt mixes, reduces the chances of early cracking and potholing, and extends the service life of roads under harsh environmental conditions.
At Opal Paints Products Pvt. Ltd., we are one of the leading manufacturers and suppliers of premium-grade antistripping agents in India. Our flagship product, SUPER-BOND XS, was tested and approved by the Central Road Research Institute (CRRI) and conforms to IS 14982:2001 standards. We supply our solutions to national highways, PWD departments, airport runways, and other heavy-duty infrastructure projects.
Stripping is the loss of adhesion between the bitumen binder and aggregate in asphalt. When water infiltrates this bond, it leads to weakening of the pavement structure. This causes potholes, cracking, rutting, and premature road failure — increasing maintenance costs and reducing the lifespan of the road.
Antistripping agents are chemical additives that promote strong adhesion between asphalt binder and aggregates. They modify the surface chemistry to resist moisture damage by creating a durable bond. This ensures that even in wet conditions, the binder remains attached — improving pavement performance and durability.

Types of Antistripping Agents We Provide
We provide two highly effective antistripping solutions tailored to diverse asphalt conditions and aggregate profiles.
Amine-Based Agents
Amine-based antistripping agents are widely used in asphalt mixtures due to their cost-effectiveness and compatibility with a wide range of acidic aggregates such as granite and quartzite. These agents work by improving the chemical bond between the binder and the aggregate, which helps reduce moisture-induced damage and stripping. They are particularly effective in climates with moderate rainfall and are commonly used in highways, rural roads, and urban pavements.
Silane-Based Agents
Silane-based antistripping agents offer advanced performance for challenging environments where aggregates are siliceous or prone to moisture sensitivity. These agents chemically react with aggregate surfaces, forming a strong and durable bond that enhances resistance to water penetration. They are especially suited for high-rainfall regions, coastal roads, and areas with frequent freeze-thaw cycles. Silane-based agents are preferred for premium pavement applications requiring long-term durability.
