SikaFast 3351 Long Open Time Methacrylate Structural Adhesive

More About the SikaFast 3351 Structural Adhesive

SikaFast 3351 is a two-component structural methyl methacrylate (MMA) adhesive with a long open time. It is designed to replace traditional mechanical fasteners like welding, riveting, or screwing and provides strong adhesion on various substrates including metals, top coats, and plastics. The extended working time provides ideal conditions for larger bonding applications or those requiring additional handling and positioning. 

Being thixotropic and non-sagging, the SikaFast 3351 MMA allows for easy and precise application even on vertical surfaces. It also offers excellent weathering resistance for outdoor or demanding environments and requires minimal surface preparation. 

This SikaFast 3351 white adhesive glue has a 10:1 mix ratio and is supplied in a 490 mL (16.5 fl. oz) cartridge.

Key Features

• Long Open Time: Extended working time allows for larger or more complex assemblies
  
• Non-Sagging: Thixotropic formulation ensures precise application, even on vertical surfaces
  
• Weathering Resistant: Ideal for outdoor and harsh environmental conditions
  
• High Strength: Strong resistance to impact, peel, and shear forces
  
• Minimal Surface Prep: Bonds to top coats, metals, and plastics with little or no surface preparation
  
• 490 mL Cartridge: Suitable for high-strength bonding applications

Applications

SikaFast 3351 is ideal for high-strength bonding applications in demanding environments. Its high weather resistance makes it perfect for outdoor use, while the long open time allows for flexibility in positioning and assembly. The non-sagging formulation ensures precise application on vertical surfaces.
