Whether it's gluing plastic to rubber parts or joining metal with wood, 3M adhesives and tapes help address these common design challenges when bonding dissimilar materials:
1. Surface distortion, especially for thinner materials
2. Tedious process steps such as polishing and finishing surfaces
3. Joint fatigue concentrated at one point
Using the right adhesive for your project can help you speed up your assembly process and create a high-quality, seamless finish for your designs. Follow these steps to correctly select one.
• 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 that is suited for the environment it will be used in.
With its high surface energy, metallic surfaces bond easily with other materials. However, gap filling and isolation of substrates are a concern. Adhesives and tapes increase the area of contact for a stronger bond, while improving process speed by eliminating the need for surface preparation.
Including substrates such as glass, ceramic and wood, natural materials have medium surface energies that make bonding easy. 3M adhesives and tapes accommodate various surface properties for a lasting bond.
Generally strong and stiff, engineered plastics like polycarbonate, ABS and urethane foam perform well at higher temperatures. While not too difficult to bond, they require an industrial adhesive or tape that is resistant to temperature and solvents for optimal performance.
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.
Create strong bonds when you combine the right 3M bonding solution in your applications. Explore how they streamline the assembly process and enhance the appearance of the final product.
