More than 100 years ago, Mr. Kaspar Winkler of Zurich, Switzerland, developed advanced chemical processes to speed up the setting and curing of cement, mortar and concrete. The product Sika-1 (mortar waterproofing additive) is still widely used today, and is the result of the Sika Group, which was founded in 1910.
 
For the first few years, Sika was in the red. It wasn't until 1918 that Sika-1 was used in the Gotthard railway tunnels in Switzerland and proved to be waterproof and durable, and then Sika cooperated with the Swiss National Railways to use the product in 67 tunnels in the country.
 
Relying on excellent products and management, Sika has developed its industry globally, with subsidiaries in Asia, the Americas, Europe, etc. In recent years, Sika has increased its market share in almost all of its sales locations, despite the international recession. In January 2019, Sika acquired French building materials manufacturer Parex for 2.5 billion Swiss francs (about 2.55 billion US dollars), which is the largest merger and acquisition in Sika's history, which will significantly increase Sika's market share in the global chemical building materials market and expand its sales platform.
 
The light in the construction and industrial sectors makes Sika's household glass adhesives less visible. Compared with Dow Corning and WACKER, Sika glass adhesive is used in fewer scenarios, only in the kitchen and bathroom and indoor, both with a dosage of 300ml. Except for an imported kitchen and bathroom adhesive Sika crystal through sealing adhesive priced at 98 yuan, the rest of the products are priced similarly to WACKER, all of which are around 20 yuan.
 
Sika's glass glue products are mostly kitchen and bathroom, so they all have anti-mildew effects, but there is only one high-grade kitchen and bathroom anti-mildew neutral glue priced at 36 yuan with an anti-mildew grade of 0. Neutral and environmentally friendly, it has obtained the China Environmental Labeling Ten Ring Certification and the German EC1 (EMICODE Environmental Label) certification, adapts to most materials, is non-corrosive, can resist fungal growth, and the cured glass glue has good elasticity and flexibility, and has a long service life.
 
For example, indoor and outdoor doors and windows, gypsum board, etc. need to be sealed, Sika's anti-fouling multi-functional neutral adhesive will be a good helper. The antimicrobial ingredient makes this gel suitable even in humid environments such as kitchens and bathrooms.
