Application Methods
Your application method will depend on your unique circumstances. Generally speaking, manual application involves little investment in equipment but with higher labor costs while automated application requires little or no labor but has high equipment outlays up front. Machine-assisted application falls between those extremes: a trained operator uses a hand-held applicator to apply the adhesive, which is forced out with the aid of a battery or pneumatic system.
We're here to help.
Create innovative designs with confidence. Regardless of industry, application, or substrate, 3M offers a wide range of products that meet your bonding needs.
