For a structural adhesive to be effective, it has to closely adhere to the surface, which, as previously mentioned, depends on a material’s surface energy. In order to bond well, an adhesive has to closely adhere to the surface, and to be able to do that, the surface has to allow good contact with the adhesive, which is something that low surface energy materials don’t do.
Plastics of all shapes and types have become indispensable in our everyday lives. If you look around, you will find that an increasing number of natural materials are being replaced by plastics. This has resulted in many technical challenges, one of the biggest being bonding.
When talking about plastics, we are actually using a term that covers a wide variety of synthetic and semi-synthetic organic compounds. What is interesting is that only a small portion of plastic materials is based on petrochemicals, while most are made from renewable resources such as polyacrylate, which is derived from corn or cotton.
The adhesives from the 200MP series are based on the 3M’s innovative technology. They are in the core of many long lasting double-sided products. Widely used in many industries, especially in electronics.
Each type of materials including plastics has a specific surface energy. It quantifies the disruption of intermolecular bonds that occurs when a substrates is created. The surface energy of plastics defines the adhesion strength,…
We all have experienced the situation when we were wondering how to join details with a different surface structure (metal with wood, plastic with metal, and others). At such moments, we often face the following problem: glues or double-sided tapes do not help as they promise.
