This product can be used in variety of applications, including:
As building waterproofing agent, protective agent, RJ-OTES can be used in concrete, stone protection with good protective effect.
  • It can form a dense substrate surface by the water layer, inhibiting the penetration of water, so as to effectively prevent water seepage, sunshine,
  • rain and erosion of the substrate to extend the building life.
Used in water repellency, which have good protective performance when used on surfaces of highway bridge decks and so on.
RJ-OTES can improve the dispensability and compatibility of filler and pigment particles in coating and sealant formulations.
