Your “all-in-one” Portfolio for Professional Glass Replacement

To most drivers, the windshield is just a window to the world. To an automotive engineer, it’s part of an important safety system that supports the airbag in the event of a crash and plays an important role in enhancing the structural stiffness of a vehicle. It’s no surprise then, that windshield replacement is no simple task.

Glass replacement adhesives must meet standards, like FMVSS208/212, which defines performance requirements for occupant crash protection and windshield mounting. OEMs also have their own specifications related to safe drive-away time, modulus, antenna suitability, and more; requirements that have also become ‘standard’ for windshield repair applications.

With our Sika® Aktivator, Sika®Primer, Sikaflex®, and SikaTack® products, we offer a full variety of professional repair products for glass replacement:

  • Our PUR-adhesives are developed according to OEM requirements and meet all of their specifications
  • Our Sikaflex®-250 product family, one-component repair adhesives can be cold- or warm-applied and cure with humidity
  • SikaTack®, when combined with SikaBooster® is an accelerated adhesive system, which cures independently of humidity
  • Sika® Aktivator and Sika®Primer are proven process-friendly pre-treatment products

This “all-in-one” customized repair set allows repair facilities to professionally complete glass replacement with a short safe drive-away time that meets the requirements of FMVSS 208/212, as well as OEM requirements.

Working Together to Simplify the Repair Process

Sikaflex®-250 products are a family of one-component, PUR glass bonding adhesives for repair applications, which are designed to cure with ambient humidity. Curing times can be varied based on the specific requirements of each manufacturer; full curing of a standard one-component PUR-adhesive usually occurs within approximately 7 days.

When faster curing times are required – or sufficient humidity is unavailable – SikaTack® plus SikaBooster® can be utilized to accelerate the curing process. Sika® Aktivator and Sika® Primer pre-treatments complete our high-quality repair glass replacement portfolio.

Together, these products give repair technicians the tools needed to easily and safely complete the repair with a single-use repair package, which contains all of the components, including any additional tools, required for the job.

Offered mainly through private-label brands, these packages have been developed, tested, and approved to OEM specifications. This ensures that replacement glass can always be re-installed to the original OEM standard and that the job (when completed properly) will meet all of the vehicle owner’s safety- and comfort expectations.


In all cases, the bonding area must be pre-treated to OEM instructions. Sika pre-treatments are available in a single-use package which is easy to use and assures that the product is always fresh when needed.  Sikaflex®-250 adhesives are shipped in a single-use cartridge and, depending on the specification, either cold or warm applied. SikaTack® adhesives with SikaBooster® must be pre-heated prior to the application. Both systems can be extruded with a 1C-application gun.
