SikaFast 308 Fast Curing Methacrylate Structural Adhesive

More Info About the SikaFast 308 Methacrylate Adhesive

SikaFast 308 is a two-component, fast-curing structural acrylic adhesive with a methyl methacrylate (MMA) formulation. It comes in a 10:1 mix ratio that is supplied in a 490 mL (16.5 fl. oz) cartridge and is designed to replace traditional mechanical fasteners like welding, riveting, or screwing.

The SikaFast 308 adhesive offers an open time of 4 minutes that is great for quick fixturing in high-strength bonding applications. Its thixotropic and also non-sagging formulation also ensures precise application for bonding on vertical or overhead surfaces. The SikaFast 308 structural adhesive provides strong adhesion on a variety of substrates, including metals and plastics, without the need for extensive surface preparation. Its rapid strength development makes it suitable for demanding applications where durability and impact resistance are critical.
