SikaFast 3341 Extended Open Time Methacrylate Structural Adhesive

Learn More About the SikaFast 3341 Adhesive

The SikaFast 3341 methacrylate adhesive comes in two components and has an open time of 25 minutes. Compared to some other SikaFast products, this extended open time allows for additional handling and positioning time in larger bonding applications. The thixotropic, non-sagging formulation of the SikaFast 3341 structural adhesive also allows for precise application, even on vertical surfaces. It can be used to replace traditional mechanical fasteners like welding, riveting, or screwing and provides excellent adhesion on various substrates such as metals, top coats, and plastics.

This SikaFast 3341 glue has a 10:1 mix ratio and is supplied in a 490 mL (16.5 fl. oz) cartridge. It requires minimal surface preparation.
