Danish researchers pave the way for molecular super glue

A new method which enables the combination of metals and plastics at a molecular level has been developed by Danish researchers. This ‘molecular glue’ forms strong and tight sealing bonds between materials that would not otherwise stick together.
Many are probably familiar with the problem of paint peeling off metal surfaces due to a lack of adhesion to the metal surface. The main reason for this so-called delamination is that it is difficult to tie together the different types of materials with sufficiently strong and tight bonds.

Problems like this have now been addressed by a research group at Aarhus University in collaboration with two local companies, SP Group and Grundfos. During the past few years the research group has developed a new nanotechnology that optimizes on a molecular level the adhesion between plastic and metal.

Major industrial players such as LEGO, Kamstrup – a major manufacturer of water meters – and the British company Techflow – a supplier to the oil industry – have teamed up with SP Group, Grundfos and Aarhus University to intensify the development of commercial products based on this new discovery.

Through this partnership, the new super glue will be developed to solve many practical challenges, including protection of oil equipment, encapsulation of electronics and the development of watertight seals.
