The Henkel Group operates in nearly 125 countries around the world and includes three businesses: Laundry & Home Care, Beauty & Beauty & Adhesives. Among them, Henkel's "Black & Decker" has become a world-renowned strong adhesive brand since the 60s of the last century, and has the world's largest adhesive factory.
 
Black & Decker waterproof coating has excellent heat resistance, when the waterproof coating is applied to the surface of the object, the paint will not flow, and then it will form a film, even in the hot summer heat exposure will not easily change. At the same time, Black & Decker waterproof coating has excellent flexibility, which can not only resist the slight deformation of thermal expansion and cold contraction, but also reduce the deformation caused by severe conditions such as ground subsidence and building aging, and maintain good coverage and waterproofness. The coating can form a dense waterproof film after drying, and it will not penetrate within a certain period of time under the impact of strong hydrostatic pressure or frozen water pressure.
 
According to the different mixing ratios of emulsions and powders, Black & Decker divides waterproof coatings into two categories: adhesive and flexible coatings. Glue products have both waterproof and breathability, even if the base is wet, the waterproof layer will not bulge, excellent adhesion can also make it and the tile tightly coated, the representative product is "MW58 high-efficiency waterproof mortar", the price is about 280 yuan / 18kg.
 
The flexible coating has a wider range of application, and can be used for the waterproofing of the base layer of curved elevations, yin and yang angles and other geometric shapes, and the price of "MW60 flexible coating" is about 330 yuan / 12kg, which is slightly more expensive than the glue. The fly in the ointment is that Black & Decker's waterproof coating can only stand after 48 hours of construction, which is much slower than the 10-hour practical time of other brands, which is not friendly enough to consumers with a tight decoration rhythm.
