SikaFast 306 Structural Adhesive Overview

The SikaFast 306 adhesive is a two-component, very fast-curing structural acrylic utilizing methyl methacrylate (MMA) technology. It is designed to replace traditional mechanical fasteners like welding, riveting, or screwing and provides strong adhesion on various substrates such as metals, top coats, and plastics. It comes in a 490 mL (16.5 fl. oz) cartridge with a 10:1 mix ratio and requires minimal surface preparation. 

The SikaFast 306 quick cure adhesive features an open time of 3 minutes that makes it ideal for high-speed bonding applications requiring rapid strength development and quick fixturing. Its thixotropic, non-sagging formulation also ensures easy and precise application that is great for high-strength bonding on vertical or overhead surfaces.
