A Glue That Works on Wet Surfaces

A Glue That Works on Wet Surfaces

Glue doesn’t stick when applied on wet surfaces, or when the conditions are moist. But what if it could? Scientists at NTU’s School of Materials Science and Engineering are exploring the potential of an adhesive that does just that. It took them over a year to develop Voltaglue, an adhesive that hardens when voltage is applied. This unique property means Voltaglue adheres to the surfaces that are wet and moist. Electrocuring – the process of applying voltage to the glue can be tweaked to customise the hardness of the adhesive, thereby increasing the potential of its application in a variety of fields from medicine to construction.

  • Potential application in wide range of fields from medicine to construction
  • Minimises the need for bolts and screws, benefits the automotive makers

"We had to find a way to make glue which cures when we want it without being affected by the environmental conditions, so electricity was the best approach for us. The hardness of our glue can be adjusted by the amount of time we apply a voltage to it, which we call electrocuring."

Assistant Professor Terry Steele,
from NTU's School of Materials Science and Engineering, lead scientist for the Voltaglue research project.

Moving Forward:

Scientists are further developing the adhesive so it can be cured – and uncured with electricity, and to reduce the time it takes for the glue to harden. Your contribution will help widen the potential applications of Voltaglue in many fields.​
