1.Product introduction

The Non-curing rubberized  bitumen waterproof coating is made of rubberized asphalt. After  application, the product can remain a non-cured colloid state for a very long  time, providing an ideal adaptability to structural vibration and deformation.  This is an essential advantage of this product over other coating materials.


2. Product properties

  • The product has excellent  creep capability, excellent bonding ability against various materials like  concrete, metal, wood and glass.

  • The product has  ideal adaptability to substrate vibration and deformation.

  • The product has very  good workability, require relatively much less time for drying.

  • The product has  super resistant capability against alkali, acid, mould, salt, as well as aging.

  • The product has  excellent self healing ability and good flexibility at low temperature.

  • The product has a  high solid content, without any volatile solvent. It is an eco-friendly  material.


3. Place to use

  • The product is  particularly suitable for deformation joints and all kinds of seams in a  building.

  • The product is also  widely used in highway, railway and metro system.

  • The product is suitable  for pipe drains and water channels.


4. Operation  instruction

  • Application surface  must be solid and clean surface.

  • Ideal operation  environment temperature for the product is between 5℃ to 35℃.

  • The construction  requires special machine or device, for proper heating and melting the product,  and spraying or scraping it onto the application surface.

  • When use the product  as an adhesive to a waterproof membrane, it is recommended to coat a relatively  small area, like 20 square meter or less, then pave the membrane.


5. Storage

  • This is a flammable  product and must be stored away from heat source and fire.

  • Keep the product in  a cool, dry and ventilated place.

  • The storage life of  the product is 12 months.
