Any superglue has two problems: harmful chemicals in the composition and difficulty in detaching glued objects. It seems that both issues have been solved.
The substance is made based on agricultural waste and paper production. To 'work' glue, should be applied on the surface, moistened with water and then heated. The main adhesive ingredient here is cellulose nanoparticles, which, after the water has evaporated, form strong bonds, turning into layers of nanocrystals.
The areas glued in this way withstand the force of 90 kg. But to separate them is very simple: it's enough to pull the surfaces in different directions. Removing excess glue is also easy: you need to rub it with your finger.
The whole process takes about two hours, but this process can be accelerated by increasing the heating temperature. However, scientists do not recommend this, because if the temperature is above 50 degrees Celsius, the area of adhesion will be reduced. The technology is hoped to be used in electronics and for packaging.
