SikaFast 3531 Extended Open Time Methacrylate Structural Adhesive

SikaFast 3531 Structural Adhesive Product Description

A two-component structural glue, the SikaFast 3531 adhesive utilizes a methyl methacrylate (MMA) chemistry with a 1:1 mix ratio. It has an extended open time of 15 minutes which makes it a great choice for larger bonding applications that require additional handling and positioning time.

Its thixotropic, non-sagging formulation allows for precise application on vertical surfaces. SikaFast 3531 replaces traditional mechanical fasteners and provides excellent adhesion on various substrates including metals, top coats, and plastics. This adhesive is perfect for high-strength bonding applications where flexibility and precise positioning are critical.

This SikaFast 3531 MMA comes in a 400 mL (13.5 fl. oz) cartridge. 

Key Properties

• Extended Working Time: Provides a longer open time for larger applications or complex assemblies
  
• Non-Sagging Formula: Thixotropic paste ensures precise application, even on vertical surfaces
