3M Scotch-Weld DP8425NS Acrylic Adhesive Overview

3M DP8425NS is a high-performance, two-part acrylic adhesive with a 10:1 mix ratio, offering excellent shear, peel, and impact strength. This toughened adhesive has a 22 to 24 minute work life and provides strong adhesion to many plastics and metals, including slightly oily surfaces, making it suitable for various applications. With a fast rate of strength build, 3M DP8425NS achieves structural strength in under an hour. Its non-sag properties allow for precise application, ensuring the adhesive stays in place during the bonding process, even on vertical surfaces, making it ideal for industrial and commercial uses.

DP8425NS Features and Benefits

• Toughened Acrylic Formula: Ideal for high-strength bonding, withstanding shear, peel, and impact forces.
  
• Fast Strength Build: Provides handling strength in just 50 to 56 minutes.
