Designed for Difficult-to-Bond, Low Surface Energy Plastics

3M Scotch-Weld Instant Adhesive Primer AC77 is specifically formulated to bond difficult-to-bond, low surface energy plastics such as polypropylene, polyethylene, and PTFE. This primer is essential for achieving optimal adhesion on these types of surfaces.

Recommended Applications

This adhesive primer greatly enhances the adhesion of cyanoacrylate adhesives to various materials, including:

  • Difficult-to-bond rigid plastic
  • Polyethylene (PE)
  • Polypropylene (PP)
  • Acetal
  • PTFE
  • TPO

3M Scotch-Weld Instant Adhesive Primer AC77 is a low surface energy primer specifically designed for instant adhesives. It is important to note that this product should be tested on substrates before use, as overspray or excess primer may have adverse effects on certain substrates, especially some plastics. The application process is simple and can be completed as follows:

  1. Apply the primer to all difficult-to-bond plastic surfaces.
  2. Allow the solvent to dry completely.
  3. Promptly bond the surfaces using a 3M Scotch-Weld cyanoacrylate adhesive.
Understanding Instant Adhesives

Instant adhesives, also known as cyanoacrylate adhesives, are fast-acting glues commonly used in industrial and household applications. These adhesives are based on acrylic resin that rapidly polymerizes in the presence of moisture, forming strong chains that bond the surfaces together.

When using cyanoacrylate adhesives, it is important to apply them thinly and apply pressure on the bond for a few seconds. This ensures that the reaction proceeds rapidly and a strong bond is formed within a reasonable time.

3M instant adhesives can be applied directly from the container and quickly reach handling strength at room temperature. Often referred to as "super hold" glue, just a single drop per square inch can bond a wide range of materials, including plastics, rubbers, metals, and wood. In fact, a 3M instant adhesive set a Guinness World Record in 2012 for being the strongest glue by lifting an 8.1 metric ton forklift in the air for one hour.
