The Self-healing non-curing rubber asphalt waterproof coating is a rubberized bituminous coating for construction waterproofing use. It is specially developed for joints, seams and places susceptible to structural vibration and deformation in buildings and constructions, as it has the capacity to maintain a non-curing semi-solid state after applied.
Its adaptability against application structure movement, as well as vibration is perfect.
Its adhesive ability at concrete surface is super and its creep property is excellent.
It possesses remarkable resistance ability to various chemical materials and weathering.
Its self healing property prevails among the coating material category, and it remains noticeably flexible in cold environment.
Its constructability is outstanding; the product needs very little time to dry after construction.
Its solid content is relatively high; it doesn’t contain any volatile solvent, and is a safe and eco-friendly product to use.
3. Application range
It is applicable for all kinds building waterproofing use, especially places susceptible to structural vibration and movement, like joints and seams.
It is also applicable for underground channels and pipes for water and sewage.
It is suitable for transportation system waterproofing, such as metro, railway, as well as highway.
4. How to use
Suitable ambient temperature for the application of the product is 5~35℃.
The product is not very demanding on smoothness of an application surface, but does require a solid and clean application surface.
The product needs special device and machine to apply. It must be heated and melted to a liquid state, then scraped or sprayed onto the application surface.
The product can also be used as a bonding material for waterproofing membrane, specially the self-adhesive bitumen type. When use it this way, to finish a relatively small area each time is recommended, like 20 square meters or so. This gives the best construction result.
