Founded in 1914, WACKER is the world's second-largest manufacturer of silicones and polysilicon, as well as one of the world's largest chemical companies in terms of R&D investment. With its strengths in innovative chemistry and new technologies, it has been a leader in its core business areas such as semiconductors, polysilicon, polymers, specialty chemicals and silicones. Since its foray into the Chinese market in the 70s, WACKER has sold more products in China than in Germany.
 
WACKER's best-known products in foreign markets are VAE dispersions for sealants and caulks. Due to the popularity of heating, ventilation and air conditioning (HVAC) systems in foreign countries, cracks in the system's pipes can add hundreds of dollars a year to electricity bills, WACKER has developed VAE emulsions that give sealants and caulks the flexibility they need, ensure that sealants remain adhesive, and that joints are strong and tight, even under high loads.
 
WACKER glass adhesive is also one of its adhesive products, and the price of about 20 yuan is more cost-effective than Dow Corning. Designed for sealing, repairing, bonding, and gap filling in a variety of domestic and industrial applications. The application scenarios are as comprehensive as Corning, covering everything from glazing, door and window caulking, air conditioning ducts, to automobiles and boats. Mostly one-component neutral glue. WACKER is also widely used in China, such as the Bird's Nest in Beijing and the Drum Tower in Xi'an. However, in the folk, it is more famous for fish tank glue products.
 
Fish aficionados may be familiar with the glass glue for the WACKER 121 Aquarium. The product is dedicated to fish tanks, certified by TUV Rheinland, and the colloids do not hurt the fish eggs, which can ensure the normal hatching of the fish eggs. At room temperature, it reacts with water in the air to form a silicone elastomer with long-term flexibility, which has strong adhesion to glass, plastic, ceramic glaze and other materials, and can prevent the fish tank from cracking. At the same time, it has excellent long-term water resistance, longer service life than ordinary fish tank glue, and 300ml packaging products can be bought for 39 yuan. This glass glue can be used not only in aquariums, but also in ceramics, plastics or lacquered wood.
 
WACKER's multi-purpose silicone sealant is one of the few types of acid glass adhesives. Acid glass adhesive is more viscous than neutral glass, because of corrosion, metal, coated glass and some inorganic materials can not be used, the scope of application is narrower than neutral glass glue. This glass glue has excellent adhesion to non-porous silicon-containing materials, such as wood, ceramic tiles, glazed tiles and other materials, and is not recommended to be used in metal, natural stone, organic rubber and other materials, with a price of 24 yuan, and no price difference with neutral glue.
