Polyurea Bridge Coating

Polyurea bridge coating life expectancy 50 years      The polyurea bridge coating film has high strength and toughness, and is resistant to impact, tearing, corrosion, abrasion, puncture and aging. It is a permanent water-blocking layer and can be exposed. Polyurea bridge coating life expectancy 50 years.The construction efficiency is extremely high. The two people can work 1000 square meters per day, and the coating can be put into use on the same day.
