Sika AG

Sika AG is a Swiss specialty chemicals company, founded in 1910, that develops solutions for bonding, sealing, damping, reinforcing and protecting structures and materials. Its products serve the construction, manufacturing, automotive and infrastructure sectors. The company operates in 102 countries and runs about 400 production facilities, combining Swiss engineering with local expertise.

The business traces back to a waterproofing agent for mortar, invented by founder Kaspar Winkler and used in construction projects including skyscrapers. Today the portfolio spans waterproofing technology, concrete admixtures that enable taller buildings, roofing systems built for extreme weather, and adhesives and sealants for vehicles, including sealing solutions for electric-vehicle batteries. Automotive applications focus on making vehicles lighter and more fuel-efficient.

Technical work at Sika covers materials science, specialty chemicals, and sustainability and carbon reduction. The company states that sustainability is embedded in its core strategy, with an emphasis on durability, reduced environmental impact and quality of life, and on helping customers build greener without compromising performance or safety. The culture is described as innovation-driven, centred on breakthrough technologies.

Headquartered in Switzerland, Sika has operated for more than a century and serves customers across construction, buildings and roofing, manufacturing, automotive and electric vehicles, and infrastructure.
