Factors to consider when choosing an adhesive

When it comes to bonding dissimilar materials 3M adhesives and tapes help to address these common design challenges:

1. Distortion of surface, especially for thinner materials

2. Tedious process steps such as polishing and finishing

3. Joint fatigue concentrated at one point

Using the right adhesive for your project helps you to maximise the outcome as well as the efficiency of the process. Select one easily with these steps.

Step 1: identify the application type

Narrow down the choice of adhesives and tapes based on the joint geometry.

Step 2: identify the substrates to be used

Take into account the surface energies and textures of different substrates.

Step 3: identify process steps for manufacture

The stage in the manufacturing process would affect the rate of strength of the adhesive and its application method.

Step 4: identify the end-use of the product

Select an adhesive or tape better suited for the environment it will be used in.

Understanding substrate types and surface energies

  • Metal

    Gap filling and isolation of substrates is a concern when bonding metals. Adhesives and tapes increases the area of contact for a stronger bond. The high surface energy of metals also make it easy to bond to other materials.

  • Traditional Materials

    Glass, wood, and ceramic may be easy to bond as it has a medium surface energy. When bonding it to a different substrate, 3M adhesives and tapes accommodates the various surface energies to form a lasting bond.

  • Engineered Plastics

    These are generally strong, stiff plastics that perform well at higher temperatures. They require an industrial adhesive or tape that is also resistant to temperature and solvents for optimal performance.

  • LSE Plastics

    Plastics with low surface energy (LSE) have an inherent resistance to wetting which makes the adhesive selection process more critical. 3M has developed plastic adhesives specifically to bond these materials.
