I checked this brand before when I bought the home-made sewing agent. I still have information! Now is the time to share with you! ~ 1.- the first-the first product in China to invent a beautiful sewing agent, and its brand Datura won a national patent. 1- exclusive-The products of Beijing UUV Cloud Technology Co., Ltd. have been continuously updated for 8 years since the first generation products were officially launched in 2003. The second and third generation products have become fully filled caulking agents, which has opened the distance with other domestic brands and established the position of the industry leader of caulking agents. Datura flower filling sewing agent completely solved the problems in the production of other brands of sewing agents in Shijiazhuang, Hebei Province. These products only make the surface layer, and the seam at the bottom must be flat. About 50% of the products overflowed during the construction, which caused great waste. At the same time, the product only makes the surface layer, which is lower than the ceramic tile, leaving a sanitary dead angle for the gap to hide and accept dirt. The product only makes the surface layer with low bonding strength, and the average life span will fall off in 3 to 6 months. Datura perfect sewing agent fully solves the above problems. During construction, all products are punched in the gaps, so that the materials can be formed at one time without seams. No matter what kind of bottom seam can be full, full and flat. At the same time, Datura perfect sewing agent is more perfect as a corner line of yin and yang, which also reflects the scientific and technological achievements of Datura perfect sewing agent. 3- Profession-We have been imitated, but never surpassed. Datura has been made for 8 years, and its products range from the first generation, the second generation and the third generation to today's fully filled type.
