Sika – Holistic solution provider for sealing and bonding

Sika provides a wide range of sealants, assembly and structural adhesives as well as direct glazing materials based on different technologies. The portfolio includes top class elastic sealing and bonding solutions to meet all requirements; at the manufacturing plant e.g. joint sealants for bus & rail or direct glazing adhesives for any commercial vehicle as well as multipurpose bonding solutions for interior and exterior applications. The growing demand in those markets is fueled by the sharper focus on energy efficient vehicles, reduction of emissions, the ever greater variety of materials use and the growing significance of health, safety and environmental issues.

Current Technologies

The Sealing and Bonding R&D department develops sealants and adhesives for our industry customers that cover a broad range of applications. To fulfill the highest requirements, the R&D department has a high competence in all important/relevant technologies: Polyurethane, Silane terminated Polymer, Epoxy, Silicone, Acrylate, Waterborne and Pretreatment technologies.

Polyurethane Technology

Polyurethane sealants and adhesives are widely used and appreciated due to their versatility to adapt mechanical properties to application requirements. Sika is recognized as the worldwide technology leader in 1C polyurethane sealants and adhesives. With our latest innovation, the i-Cure technology, Sika can offer labeling free polyurethane sealants and adhesives.

Silane-terminated polymers (STP) by Sika
Silane-Terminated Polymer Technology

Silane-terminated polymers (STP) combine the properties of polyurethanes and silicones. Sika’s STP products extend the portfolio performance, especially in the applications where less surface pretreatment and isocyanite free products are requested. Our Sikaflex Hybrid range fulfills all relevant standards for construction and industry and show excellent application properties.

Silicone Technology

Silicone adhesives and sealants are based on a polydimethylsiloxane polymer which imparts the products with high movement capability and excellent temperature and UV resistance. Our Sikasil RTV-1 and RTV-2 systems make perfect use of these advantages and are primarily used for the construction of glass facades and insulating glass units, the sealing of concrete joints, as well as the assembly of solar panels.

Pretreatment

To assure the longevity of certain applications, the substrate needs to be treated to guarantee the adhesion. Depending on substrate and application, a cleaner, an activator or a primer can be recommended. Sika offers a range of solvent, and newly also waterborne, pretreatment products.
