Incorporating Nanotechnology into Traditional Cementitious Waterproofing Coating
Traditional cementitious waterproofing coating has low flexibility and poor bonding strength on concrete substrate. With the help of nanotechnology a novel cementitious waterproofing coating is developed to have high flexibility and excellent adhesion on the substrate.
Nanotechnology |
 |
|
Nanoparticles having at least one dimension in the nanometer range can enhance the tensile strength, ductility, adhesion and other performance when they are efficiently incorporated into a coating system with uniform dispersion. A methodology has been developed to disperse the nanoparticles in the coating in order to modify the polymer cementitious coating, achieving higher elasticity and superior waterproof performance. |

◎ High Flexibility with >300% Elongation Value.  |
The incorporation of nanoparticles promotes a new load transferring mechanism in achieving high flexibility with good tensile strength, and thus covers minute cracks causes by various reasons. |

|
Application |
 |
|
The superior performance, easy application and cost-effective features further enable the developed coating to be easily applied to various construction waterproofing fields including basements, toilets, kitchens, terraces, swimming pools, water tanks, decks and flat roof. |
● Direct application on damp surfaces. |
● Adhesion to the substrate can be maintained over time. |
● Excellent waterproofing qualities-able to withstand high hydrostatic pressure. |
● Formation of a more solid and durable coating with good mechanical performance. |
● Pre-packed - Easy to mix and apply. |
