Roof Waterproofing Projects Spray Polyurea Waterproof Coating


 


Introduction                                                                                                                            


Spray Polyurea Waterproof Coating is a new type waterproof coating. A component is isocyanate compounds; B component is amine compounds with chain extender, pigment, and filler, and auxiliaries etc. Construction technology is applied by spraying to mix the two components, generating the elastic waterproof coating.

Characteristics                                                                                                                     



  • Non-VOC content. 100% solid content. Environmental friendly.

  • Fast curing, no flowing phenomenon, can be easily applicable on curved, inclined and vertical surface etc.

  • Not sensitive to water and moisture, not influenced by environment and moisture when applied waterproof coating.

  • Thickness can be from 100μm to several cm, preventing from repeated application problem. 

  • High physical properties, such as tensile strength, elongation, abrasive resistance, anti corrosion ability.

  • Long term of heat stability under 120°C, can bear short term of 150°C impact.

  • Various colors available.

  • Hardness from Shore A30 to Shore D65.
