Characteristics of special polyurea material for planting roofing

(1) fast curing speed and high construction efficiency. The curing speed of polyurea spray is very fast, generally curing in a few seconds or dozens of seconds, 1h after the walking strength, the construction site can enter the next process. Polyurethane spray molding thickness can be set arbitrarily, from 0.5mm to a few mm can be completed in one time. In the vertical plane or even the top surface spraying can also ensure smooth and smooth, will not flow phenomenon.

(2) strong adaptability of construction environment. Because polyurea reacts very quickly at room temperature, water molecules in this system have no time to react with isocyanates, so ambient moisture does not adversely affect the quality and surface of the coating. This avoids the problem of the damp environment that often encounters in construction of polyurethane waterproof coating, convenient construction.

(3) high intensity. The modulus of spray polyurea is similar to that of rubber, that is, it can maintain higher strength while having higher elongation at break. Through formula adjustment, spray polyurea tensile strength is generally 8 ~ 22MPa, this range basically covers the performance of plastic, rubber and glass steel, used for waterproof, excellent performance.

(4) excellent aging resistance. Due to the special molecular structure of polyurea and the absence of catalyst in the formula, the spraying polyurea has excellent aging resistance. The aging resistance of polyurea coating with aliphatic group system is more excellent.

(5) good salt corrosion resistance. Spray polyurea coatings as anticorrosive coatings, in addition to the resistance to dilute acid corrosion, but also to salt or salt spray corrosion has outstanding tolerance, which makes it especially suitable for coastal areas, both waterproof and anticorrosive.
