Gammadot is participating in a novel research initiative which is looking into the degree of cure in liquid resin systems
These present major challenges - not least to test equipment where there is a clear risk of effecting a permanent bond in the instrument sample cell.
Disposable plates can be used, but this means that every system must be treated as a worst-case scenario.
There are non-rheological approaches to cure monitoring, but it is always difficult to make direct correlations among the different methods.
The new research is revisiting concepts of degree of cure from both pure and applied perspectives.
It contrasts what can be delivered against what is expected.
Degree of cure in real time is one challenge to be addressed.
Technologists do not want to wait until the cure is over to establish progress at an intermediate stage.
Nor do they want to assume that the start is zero percent cure - all reactive systems have a shelf life.
Key questions being asked include: was it zero cure at the start?, and how far has the cure progressed now?.
These are among the issues being investigated in this new research which will examine the way we use our existing instrumentation and consider what new options there are.
