Sealing & Bonding

Backed by unrivalled expertise with automotive applications, the advanced Sikaflex® portfolio of one-component adhesives and sealants has been specifically designed to provide a fast, easy solution in the automotive car body repair process. The broad range of Sika adhesives and sealants include solutions for seam sealing, spray- and brushable seam applications as well as for bonding small parts to the vehicle.

Sprayable Sealants

Sikaflex® sprayable sealants were designed for use as spray- and brushable elastic sealants (surface areas and beads) for seam sealing and lap joints in vehicle body construction and to restore the original factory finish in collision repair.

Seam Sealing Tapes

Sikaflex® Autotapes were developed as a quick and effective solution to reproduce the look and function of factory provided seals.  


Sikaflex® technology has contributed significantly to innovation in vehicle design, since it allows designers to create bold and unusual shapes by combining different materials such as glass, plastics and lightweight metals.  

Sikaflex® AT Series

The Sikaflex®-AT series products utilize a new type of Silane Terminated Polymer (STP) which encompasses the best properties of our PU and modified silicone (MS) technologies. Designed for easy application with low emissions, they are ideal for a wide range of sealing and bonding applications.

Backed by more than 2000 over-painting and paint adhesion tests, our Sikaflex®-AT products work well with modern over-paint systems. They can be applied wet-on-wet, or after a longer period, regardless of the climatic conditions.

The Sikaflex®-AT series for seam sealing provides an aging-resistant and permanently elastic seal, with good adhesion to all of the most-commonly used materials, including metal primers, paint coatings, metals, painted plastics and plastics.
