Bitumen SC70 is a slow-curing cutback bitumen made by blending standard penetration-grade bitumen with a slow-evaporating petroleum solvent. This combination gives it excellent fluidity and deep penetration properties, which make it perfect for prime coating and patching applications.
At Basekim, we supply high-quality SC70 bitumen that meets international technical standards. Thanks to our rigorous testing and reliable packaging, customers around the world trust our products for infrastructure projects of all sizes.
Bitumen SC70 is specially formulated for road surfaces that need time for proper absorption. Since it contains a high-boiling solvent, it cures slowly. That slower evaporation process allows the product to soak deep into granular bases before hardening. As a result, roads built with SC70 maintain better adhesion and durability.
Because of this extended working time, SC70 provides flexibility during application. It helps workers cover surfaces evenly without rushing. Even in warmer climates, SC70 performs consistently and allows longer handling without premature drying.
Engineers prefer SC70 for roads that will face moderate traffic and harsh weather. When applied correctly, it forms a tight seal that protects the surface against moisture, cracks, and erosion.
At Basekim, all SC70 batches are quality checked before shipping. The table below highlights the essential physical properties according to standard testing:
| Property | Test Method | Specification |
|---|---|---|
| Kinematic Viscosity @ 60°C | ASTM D2170 | 70–140 cSt |
| Flash Point (Tag Open Cup) | ASTM D3143 | Min 38°C |
| Distillation Residue | ASTM D402 | Min 55% by volume |
| Penetration of Residue | ASTM D5 | 100–250 dmm |
| Ductility of Residue | ASTM D113 | Min 100 cm |
| Solubility in TCE | ASTM D2042 | Min 99% |
Bitumen SC70 is widely used in priming and patching. Because it soaks into unbound base layers effectively, it creates a solid foundation for the final asphalt layer. This makes it ideal for rural roads, parking areas, and industrial zones.
It also works well for light surface treatments and tack coats. When roads need extra bonding strength or protection from water damage, SC70 is often the best option.
In addition, contractors find SC70 easy to work with. It flows smoothly from tanks or sprayers, covers surfaces evenly, and reduces the risk of mistakes. With the correct curing time, the treated area becomes more resilient and long-lasting.
