Product Characteristics

A)Good low temperature flexibility,it has no crack when temperature drops into -20℃;Excellent heat resistance,it has no flow when temperature reaches 90℃

B)Great tensity,prolonged life span,easy to use,less contamination

C)Suitable forⅠand Ⅱgrade constructional waterproofing project,especially for cold area and the project of frequent structural deformation

 

Application

Extensively used in the waterproofing projects of industrial and residential buildings at the roof,wall,basement,road,bridge,tunnel,parking lot,swimming pool.As for large deformation projects,it’s suggested that we should choose PY type of waterproofing membrane with better tensity,otherwise it should go with more economical G type
