R930 is a non-sagging type, and R930L is a self-leveling type. They are both single-component neutral curing sealants. The modified silane sealant is specially designed for long-term weather-resistant sealing of expansion joints, shrinkage joints, and longitudinal joints of airport runways, highways, tunnels, bridges and other concrete or asphalt pavements. It has low modulus and high displacement characteristics and is suitable for Displacement of concrete joints.
