1.Overview

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.


2. Characteristics

  • 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.
