3M Scotch-Weld Structural Acrylic Adhesives are designed to improve both productivity and performance, while reducing environmental concerns and costs.

Manufacturers around the world rely on acrylic adhesives to design and produce products. Acrylic adhesives improve aesthetics, bond to plastics and metals, and even deliver a secure bond between oily or contaminated surfaces. But despite improving many aspects of the assembly process, traditional acrylic adhesives have been challenged by high levels of odours that can cause environmental health and safety concerns; longer set times that slow assembly processes; lower impact resistance that result in brittle bonds; and limited shelf life.

The 3M Scotch-Weld Structural Adhesives product development team focused on solving these challenges, and the result is its next generation of structural acrylic adhesives. Key features of these new acrylic adhesives include:

1. Lower odour - The 8800 family of products features a new low odour, non-flammable formulation. They are a dramatic improvement over traditional formulations, and will help improve environment and worker health.

2. Faster cure - DP8805NS cures almost twice as fast as ordinary acrylic adhesives. It can reach over 1,000 psi of overlap shear strength in less than nine minutes. The advantage is higher throughput and increased productivity.

3. Higher impact resistance - DP8405NS has more than three times the impact strength of conventional acrylic adhesives. Higher impact resistance makes it ideal for many industrial applications, helping build stronger products for challenging applications. 

4. Longer shelf life - 3M’s Next Generation Structural Acrylic Adhesives do not require refrigeration, making them easier to store. They also have an 18-month shelf life — more than double that of conventional acrylic adhesives — which can help reduce scrap and disposal costs due to expired inventory.

3M Scotch-Weld Structural Acrylic Adhesives are designed to improve both productivity and performance, while reducing environmental concerns and costs. The product is available through Adheco, a Toronto-based company that provides adhesives, pressure-sensitive tapes and abrasives to the industrial market.
