Technical troubleshooting

Diagnosing formulation and processing problems that may be linked to the filler.

Overview

Surface defects, unexpected gloss, viscosity drift or dispersion problems can have several causes. The filler is one possible cause and is rarely the only one.

We work through the problem with your team in a set order and check each likely cause before drawing a conclusion.

What we look at

Surface and appearance defects
Roughness, specks, craters or uneven gloss in the finished film.
Processing issues
Changes in viscosity, flow, extrusion behavior or dispersion during production.
Batch variation
Differences between production batches that need to be traced to their source.

How we approach it

The work follows a fixed sequence, agreed with your team at the start.

  1. Describe the problem

    What is observed, since when, in which products and under which conditions.

  2. Collect samples and data

    Samples of the affected product, the filler batches involved and the relevant process information.

  3. Analyze the filler

    The filler is checked against its specification, with particle size and appearance first.

  4. Test the likely causes

    Each hypothesis is tested in the formulation, one variable at a time.

  5. Recommend and confirm

    A corrective action is proposed and confirmed with your team in the application.
