Accelerate handling strength in 2K PUR adhesives

This paper is devoted to accelerating the time to obtain the handling strength of two-component polyurethane adhesive, which was newly purchased by the company Magna Exterios (Bohemia) and had to be tested. In order to speed up the analysis of the problem, methods of IR emitters and temperature chambers were selected to be compared with curing using only the ambient atmosphere. In the second part of this paper, the maximum strength of the bond which withstand the test without damage was measured. The results show that the method of accelerating curing process using an IR emitter is the fastest, but the economic side of things must be taken into account, because it is also the most expensive option of acceleration. The temperature chamber is almost twice as slower, but cheaper. At the end of the thesis, the economic efficiency of the new adhesive line solution is evaluated and how much money can be ideally saved
