1, BH2 waterproof coating is a one-component waterproof coating prepared by polymer
modified asphalt technology. This product has the advantages of environmental protection and
construction convenience of water-based coatings. In addition, due to the addition of a variety of
special additives, it has the characteristics of strong adhesion and high elongation after curing. The
most suitable application is mechanized spraying.
