Characteristics of product
Roadseal Sealant, created from new technology, is used for repairing the cracks in asphalt and concrete road, bridge elastic joint and traffic signal sensor. Construction using Roadseal Sealant can be done in less time and amount of cost, compared to constructions using other method.
3 Key Technology
Characteristics of product
- Improvement in characteristics in high temperature :
- Penetration, Flow rate reduced
- Restoration rate, softening point increased - Improvement in characteristics in low temperature :
- Cohesiveness in low tempera
- ture increased - Improvement in resistance rate :
- resistance increased - Improvement in cohesiveness with concrete :
- Cohesiveness in normal and low temperature increased
