| Résumé : |
JET-BLACK coatings are especially popular in the automotive industry. A demand for these coatings are growing up worldwide. It is a necessity to adjust the deepness and the colour shade of such coatings on the request of designers or on original colours, “OEM-Original Equipment Materials”, of the automotive industries. To produce consistent black paints in a good and required quality, it Is essential to know the paint manufacturing parameters, which will influence the final results. The method of “Design of Experiments” (DoE) can help here and is used for this study to gain information from the experimental results as much as possible.
Hence the question arises : “What can the developer vary in order to obtain the desired coloristic properties, as regards pigment carbon black, jetness and hue?”
The choice of pigment black ?
An optimization of the formula ?
How can the dispersing conditions be optimised ? |
| Note de contenu : |
- The choice of the appropriate pigment carbon black : Particle size - The surface chemistry - Interim conclusion
- Optimisation of the formula : How to obtain a higher jetness or a blue undertone ?
- Statistical research planning in general : Optimising dispersing conditions
- Goal parameters : Jetness : My - Blue undertone – Gloss – Haze – Plan of testing
- Discussion of the results
- Summary of the findings : Which solvents are best suited ? – Influencing parameters : pigment carbon black concentration – Influence of moisture content – Influencing parameter : dispersing time - Influencing parameter : size (diameter) of the grinding media |
