The Next Generation of Body Shop Adhesives and Sealants

Backed by unrivalled expertise with automotive applications, our advanced portfolio of Sikaflex®-AT one-component sealants has been specifically designed to provide a fast, easy solution in automotive paint shops.

Our Sikaflex®-AT series products utilize a new type of hybrid polymer 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.

For spray applications, our Sika® Spray Gun works with compressed air and uses PE cartridges. Designed for use with Sikaflex®-529 AT sealants, it produces a consistently smooth spray finish along seams, folds, and lap joints. It also allows technicians to make fine adjustments to the spray, which allows repair technicians to achieve a high-quality surface finish on narrow seams, as well over wider application areas.
