   SWD952 Series SH116 One component moisture cure

 polyurea polyurethane (elastic) system corrugation

  sheets roof special anticorrosion waterproof coating

 ­

Descriptions                 With the development of industry, the corrugation sheets roof has been widely used in various factory buildings in China. In usually the serious rusts and corrosions take place in the connection and screw fixing position of the roof then damaged it after 4 -5 years application by the industrial atmosphere and acid rain then lead roof to leak, and no able to work efficiently. In addition, influenced by weather temperature variation in summer and winter, the large shrinkage will take place in the seams between corrugation sheets then causes the common waterproof materials to be crack, peel off then finally failed waterproof function. The corrugation sheets roof special anticorrosion waterproof coating developed by SWD polyurethane Co., USA has overcame the disadvantages of common coating and gained great favor in owners and engineering business with its high quality and excellent protective effect in the Americas.

                                                                                

 

Characteristics             Coordinate safe MDI system with non-benzene solvent for environmentally friendly basic resin, the product is processed into environmentally friendly coating. The coating cured by absorption and reaction with air moisture then generated the high molecule chemical structure. Inside of the high molecule structure of formed film coating contained except large amount of carbamate bonds but also ester bond, biurea bond methyl allophanate bond which greatly increased wear resistance of coating to bear industrial corrosion environment and natural weather damages, such as dust, hail and etc. With high density, flexible and high adhesive strength, the coating can firmly bond with corrugation sheets roof to be integrated and worked as the real waterproof skin protection. It also avoided coating cracking and peeling caused by corrugation sheets roof shrinkage distortion, so as to extend its life span to more than 20years.
