About Sika
Sika AG is a Swiss specialty chemicals company headquartered in Baar (ZG). The company develops and produces systems and products for bonding, sealing, damping, reinforcing and protection in the construction sector and in industry. Manufacturing is based on five core technologies: Concrete Technology (admixtures and additives for concrete, cement and mortar), Cementitious Systems, Coating Systems, Adhesive Systems and Thermoplastic Systems. Materials used include polymers such as polyurethane (Sikaflex), silicone (Sikasil), thermoplastics and polycarboxylates (PCE), as well as fiber composites (Sika CarboDur). Customer industries include the construction and transportation industries, the automotive industry and infrastructure construction, such as tunnels, bridges, dams, roofing and facade technology. Sika is represented with subsidiaries in 103 countries and produces in over 400 factories. In 2025, 33,707 employees generated revenue of CHF 11.20 billion.

Materials and Core Technologies
Polyurethane (Sikaflex)
One- and two-component adhesives and sealants, used in the automotive industry since 1980.
Silicone (Sikasil)
Silicone-based bonding and sealing systems, e.g. for the insulation of glass facade elements.
Thermoplastics
Thermoplastic membranes and systems for roofs, waterproofing and lightweight construction applications.
Polycarboxylates (PCE)
PCE-based superplasticizers for improving the workability of fresh concrete.
Fiber-reinforced composite (Sika CarboDur)
Fiber composite profiles for post-installed reinforcement and strengthening of concrete load-bearing structures.
Concrete admixtures and additives
Admixtures for concrete, cement and mortar for controlling workability, water tightness, durability and strength.
