| Résumé : |
We describe a sophisticated surface additive technology and propose suitable measurement methods to predict the behaviour of multi-layer systems in terms of coatability. Such methodology is an indispensable tool for guiding additive selection, and it significantly reduces the time and cost associated with (re)formulation. |
| Note de contenu : |
- Chemical composition of the tested additives
- Unique properties achieved with the latest generation of levelling additives
- levelling behavious and visual appearance of a conventional clearcoat
- Surface tension ad surface smoothness (SLIP) of a conventional clearcoat
- Surface-analytical parameters that described compatibility between coating layers
- Evaluation of the WoA and S of a conventional clearcoat
- Application in a two-colour system
- Potential in low temperature cured systems
- Table 1 : Comparison of a standard silicone additive with the new additive structure Macro 2 in a conventional 2-pack refinish clearcoat : long wave (LW), short wave (SW) and distinctness of image (DOI). The first layer of coating was recoated with a second layer of the same coating after different flash-off times |
