Product Description
R930 is a non-sagging type, and R930L is a
self-leveling
type. They are both single-component neutral curing sealants. The
modified silane polymer 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.
Application
1. Used for seam sealing of airports, highways, and high-speed rail lines.
2. Used to seal the joints and grouting joints of other concrete pavements.
3. Used for sealing of subway projects, tunnels, bridges and other projects.
4. Used for caulking and waterproofing of water conservancy projects and reservoir dams.
5. Used for roof caulking waterproofing of industrial and civil buildings.
