The ORONTEC-Portfolio part 3

Let's continue with part 3 of the series -here is the next example of why early (process) control pays off.

2. Shear stability analysis

Imagine you are painting and the color drifts over time - and you only see it when you connect it to another painted part (see picture). That is when the excitement rises - “how could this happen?”

Answer: when the paint is circulated in a pipeline, considerable shear forces can act on the paint over time. If the product is not stable under these circumstances (e.g. metallics whose slurry process was interrupted too early), the color shade can change over time.

It is expensive and time-consuming to test the stability at the customer's site first - stopping the line, emptying, cleaning and refilling the system (with large quantities of material!) and then pumping it in a circle for a long time is not a productive process at the customer's site!

With the Q-Chain? PolyShear, circulating under shear using as little as 1 liter of material can be tested in the laboratory before the paint is even sampled by the customer! The Q-Chain? LCM is ideal as a detector for the stability of the sample (especially for metallics!), as the time required for a measurement (less than 5 minutes) fits perfectly with the simulation - especially if you want to follow a fast process.

The advantages? They are actually obvious:

• No blocking of the customer's paint line for stability tests
• No complaints due to color instability
• with 1 liter of material per test, the tests can be carried out on a lab scale and thus early in the development process BEFORE sampling a new product to the client
