Henkel AG is one of the world's largest suppliers of applied chemical products and one of the world's top 500 companies, and was named the most prestigious company in the industrial industry in the 2018 Fortune magazine list of the world's most admired companies.
 
Henkel is one of the world's leading global strategic brands for adhesives, including Medeland, Henkel Black & Decker, Loctite and Mercure, and the well-known Schwarzkopf is part of the Henkel Group, which is engaged in a wide range of businesses such as detergents and home care, cosmetics and beauty products.
 
For products with low technical content such as putty powder and adhesives, a considerable part of the cost actually comes from the storage and transportation stage, so such products generally follow the principle of nearby production and sales, so the number of factories and branches can prove the strength of the enterprise to a large extent, and big brands generally have a number of factories or branches across the country.
 
Henkel Black & Decker has more than 20 factories and offices across the country, and Shanghai "Dragon Factory" is the largest adhesive factory in the Asia-Pacific region and even in the world, but Black & Decker is mainly glue, accounting for more than 80% of total sales, putty powder products are not much, there are only 2 products on sale online, both are cement-based inner wall layer putty, respectively, MP20E cement-based anti-mildew putty and MP20C cement-based water-resistant putty, in addition to an MP20S offline.
 
In fact, there are certain problems with such a product line as Black & Decker, according to the decoration process, in the wall base treatment process, the more commonly used are interface agent, bottom leveling putty, and surface layer putty, so a mature product line should at least include these three types of products, in order to ensure the compatibility between products to the greatest extent. However, judging from the products on sale at Black & Decker, there are only two types of interface agent and surface putty, that is to say, if the flatness of the base wall is poor and the bottom putty is coarsely leveled, you can only use other brands of products.
 
MP20E should be the highest positioning model among the three, the price of a single package is 88 yuan, in addition to the necessary water resistance of cement-based products, at the same time more focus on the anti-mildew effect, its mildew level can reach the GBT1741-2007 "paint film mold resistance determination" standard in the highest level.
 
The difference between MP20C and MP20S has always been a matter of opinion, some people say that MP20S is gypsum-based, MP20C is cement-based, in fact, this is not the case, from the packaging point of view, both are cement-based water-resistant putty, there is not much difference, but MP20S appeared later, there is no green ten-ring environmental protection logo on the early packaging, I don't know whether the follow-up has passed the certification, you can also pay attention to it when buying.
 
Based on all aspects of information, MP20C and MP20S are purely different channels, MP20C is mainly used for online sales, and the offline B&Q channel sales are also this model, and MP20S was handed over to the national offline agents in addition to B&Q, there is not much difference between the two, it can be understood as the same product, two kinds of packaging. However, some users have reported that MP20C has better adhesion than MP20S, and MP20S is softer during batch scraping, but this has not been further confirmed, and it is likely that it is just a subjective feeling.
 
Black & Decker cement-based putty has better water and mildew resistance than ordinary gypsum-based putty, which is very suitable for humid areas in the south, but there are common problems of cement-based putty: the grinding time is not easy to master, and if the time is too late, the wall will be difficult to polish because it is too hard. Some construction teams in order to polish conveniently, will scrape a layer of gypsum putty on the surface layer of cement putty or even the traditional "old powder", "double flying powder", etc., this practice is actually wrong, which is equivalent to giving up the advantages of cement-based putty water resistance and scratch resistance, purely for the convenience of grinding and reducing the performance, and it is not advisable.
 
Due to the strong alkalinity of cement-based water-resistant putty, if you also need to brush latex paint and other coatings on the putty, you must brush the alkali-resistant primer, which is used to close the cement wall, moisture-proof and alkali-resistant, otherwise when the base alkali is precipitated in the later stage, the topcoat is easy to change and fall off, which seriously reduces the color uniformity of the color coating.
