polyurea paint for prilling tower wearable anticorrosion coating
Characteristics
The coating film is cured by reaction and absorption with air moisture then obtained high adhesive strength with substrate. The film is dense, flexible be able to adapt the certain deforming of substrate without cracks. It contains large amount of urea bond, biuret bond, urethane bond and hydrogen bond to get excellent physical properties and anticorrosion performance. It has high performance of acid resistance, alkali and salt resistance, waterproofing, temperature variation and chemical resistance. It is easy to apply with brush, roller or regular airless spray units. The service life can reach above 25 years if strictly confirm the regular application standard.
