Adhesive bonding combines two or more surfaces with a viscous substance. Strouse utilizes roll based adhesives to bond similar substrates and bond dissimilar substrates.

 

The most crucial consideration for adhesive bonding is to know the kind of stresses involved. There are four main types of stress: tensile, shear, cleavage, and peel.

 

Adhesive Bonding Stresses

Adhesive bonding solutions enable organizations to streamline the assembly of custom products.

There are two main types of assembly adhesives, permanent bonding, and temporary bonding adhesive.

Permanent Adhesive Bonding Solutions

Bonding tape like 3M VHB and acrylic foam tapes are used to replace rivets, welding, and fasteners. These adhesives typically form a stronger permanent bond.

 

When two substrates pull apart, fasteners and rivets put a great deal of stress on small areas, giving way to potential product failure. Permanent bonding solutions, such as 3M VHB, allows the pressure to be evenly distributed throughout the area of the tape as opposed to small points along the substrate.

Temporary Adhesive Bonding Solutions

Temporary bonding tape is also known as removable or repositionable tape. The adhesive can place on a substrate with strong adhesion and holding properties, but it can also easily be removed or repositioned for some time. Temporary bonding tape is ideal for applications like reclosable packaging, removable or changeable gaskets, and other products where temporary holding is required.

 

You can find assembly adhesives with unique characteristics such as bonding tape that can withstand weathering or extreme temperatures. Each application is unique.

What are the Advantages of Adhesive Bonding?

The benefits listed below are not limited to any particular industry. Strouse has used adhesive bonding across many sectors helping our customers improve processes, increase reliability, and reduce costs. Anything from massive machines to strollers to medical devices to automobiles. Adhesives have a place in every industry.

Advantages:

  • It allows for an even distribution of stress loads.

    • Even distribution reduces the concentrated stress on the joint compared to a riveted joint or spot weld.

    • A fastener exhibits all of the stress in one small area. 

  • It allows the joining of dissimilar materials as well as various substrates.

    • Metal, Plastic, Glass, Rubber, Ceramic, Skin to Plastic/Metal, Fabric.
    • Adhesive bonding can be used to bond almost any combination of surfaces.
    • Assembly methods, like welding, are limited to combinations of metal-to-metal or specific plastic-to-plastic substrate attachment.
      • Adhesive bonding allows for the ability to bond a much more extensive range of substrates. Combinations include plastic-to-metal, glass-to-plastic, rubber-to-metal, and other combinations.

 

  • The adhesive creates a thin, virtually invisible joint.

    • Sometimes aesthetics are just as important as functionality, and adhesive bonding can significantly improve the aesthetic of a product.
    • No weld burns or protruding fasteners - just smooth, clean lines.

 

  • It will adhere and seal at the same time.

    • In addition to bonding, most adhesives also provide the benefit of a seal, which is frequently an overlooked benefit.
      • It helps protect the surfaces from corrosion.
    • If you’re a manufacturer that uses mechanical fasteners, you often need to use an O-ring or gasket to keep outside elements away from your assembly. Using an adhesive eliminates this need.

 

  • It resists vibration and flexing stresses.
     
    • Automotive and Transportation Industries benefit the most from this. However, a lot of other devices from other industries experience these stresses quite frequently.

 

  • Adds very little weight to the materials.

 

  • Are Easy to Automate.
     
    • Robots and automatic dispensing are commonplace these days.
    • We have a partnership with Accuplace to be a one-stop-shop in this regard.
      • Automation increases efficiency, consistency, and accuracy.

 

  • Joints can be electrically and thermally conductive or insulating.

 

  • Has the Ability to Fill Large Gaps.

    • Filling significant gaps can improve structural integrity, encapsulate sensitive components, and dampen movement or vibration.
