  1. What is 3M™ Scotch-Weld™ Acrylic Adhesive Accelerator A3-2?

    3M™ Scotch-Weld™ Acrylic Adhesive Accelerator A3-2 is a green, solvent-based accelerator that helps increase the cure speed of certain acrylic adhesives by promoting more efficient chemical reaction between the adhesive and substrate.

  2. What types of substrates can I use with this product?

    The 3M™ Scotch-Weld™ Acrylic Adhesive Accelerator A3-2 works best on metals like aluminum, brass, stainless steel, and copper. It also adheres well to plastics such as ABS, polycarbonate, thermoplastic elastomers (TPEs), and PVC.

  3. How does this product compare to other accelerators in the market?

    Compared to liquid accelerators or commonly used powder activators available in most markets or trades locally suitable for bonding similar surfaces variety; This green-colored accelerator comes as a single-component solution that eliminates mixing ratios. Thus ensuring fast efficiencies reliably giving you good bonding results.

  4. Are there any precautions I should take when handling this material?

    Yes! When handling 3M™ Scotch-Weld™ Acrylic Adhesive Accelerator A3-2 always make sure to wear appropriate gloves,because it irritates skin upon direct contact.To ensure safety on both yourself and surrounding materials while applying,to prevent damage from over-spray depending on ventilation controls at your work area including floor coatings,you may want to consider using overspray protection netting or masking tape prior using spray method into equipment before repair/fixing applications

Quick Rate of Cure Provides Fast Strength Build-Up

3M™ Scotch-Weld™ Acrylic Adhesive Accelerator A3-2 is an accelerator (Part A) that is designed to be mixed with the base (Part B) for a two-part acrylic adhesive, a B/A system (base acrylic adhesive sold separately). This accelerator has a 10:1 mix ratio and features an exceptionally fast rate of strength build-up, providing structural strength in minutes. The system is formulated to produce tough, durable, impact-resistant bonds as well as a non-sag adhesive for accurate application. These toughened products offer excellent shear, peel, and impact performance. They provide improved adhesion to many plastics and metals, including those with slightly oily surfaces. Selected, Part B, acrylic adhesives include: DP8805NS, DP8810NS, and DP8825NS.

Recommended Applications
  • Metalworking such as HVAC, appliance, sporting goods, and specialty vehicles
  • Sign manufacturing such as panel to frame bonding, trim attachment, letter bonding, and frame assembly
  • Bonding plastics, composites, and powder coats to metal
Formulated to Produce Tough, Impact-Resistant Bonds for Durability

3M™ Scotch-Weld™ Acrylic Adhesive Accelerator A3-2 is formulated as a part of a tough, reliable solution that quickly produces the shear, peel, and impact performance for those demanding applications that require fast results. For structural strength in minutes, look no further than the engineering of 3M, putting science to work.

Easy Adhesion with Acrylic

Acrylic adhesives, often referred to as epoxy adhesives or epoxy glue, are two-part adhesives that provide excellent bond strength and durability, although slightly lower adhesion than 2 part epoxy in some situations. However, acrylic glues have several features that make them easier to use, including a much faster cure speed, higher tolerance for oily or unprepared bonding surfaces, and the ability to bond a wide variety of materials, including nearly all plastics. Newer acrylic adhesive formulations are room temperature stable with a moderate shelf life.
