SikaFast 3511 Peel Resistant Methacrylate Adhesive

SikaFast 3511 Structural Adhesive Product Description

SikaFast 3511 is a two-component, fast-curing structural acrylic adhesive utilizing methyl methacrylate (MMA) technology. It is supplied in a 400 mL (13.5 fl. oz) cartridge with a 1:1 mix ratio.

This SikaFast 3511 MMA features an open time of 4 minutes, so it is ideal for high-strength applications that require quick fixturing. Its thixotropic, non-sagging formulation also promotes easy and precise application, especially on vertical or overhead surfaces. Made for structural bonding, the SikaFast 3511 adhesive is designed to replace traditional mechanical fasteners like welding, riveting, or screwing. It also provides strong adhesion on various substrates including metals, top coats, and plastics without the need for a lot of surface preparation. Its rapid strength development ensures fast and reliable bonding in demanding applications.
