Supports of Soundproof Wall with polyurea
coating, harmless to the human body

This is a polymer created through a chain reaction and an highspeed hardening material with a resin that exhibits an extremely high reaction speed. It is applied at a high-temperature via a high-pressure spray coating method while being harmless to the human body and featuring excellent resistance to wear, chemicals, and impact. It is also a support for soundproof walls coated with polyurea, getting rid of the hot dip galvanization method that has potential for defects due to rust, etc.

Eco-friendly, non-reflective matte coating

  • Various colors can be produced according to the soundproof wall design.
  • Eco-friendly substance no eluate.
  • Matte coating with no reflection of light.
  • Outstanding resistance to corrosion, acid, and wear.
  • High hardness and strong adhesion.
  • Easy to repair defects due to exclusive reinforcing agent and re-coating.
