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.
