Automated testing of lacquered, painted and coated surfaces to environmental degradation with LISSY
23.10.2009
Lacquered, painted or coated surfaces can be exposed to degradation from contact with liquids such as rain water or surface water during routine use.
This water can be contaminated with acids, bases, organic solvents, solvent mixtures (oil, petrol) or polymeric substances such as tar and sap, which can degrade the finish of the coating.
With LISSY, it is possible to evaluate the effect of these substances on different surface coatings and at different temperatures (-20°C to 200°C):
E.g.:
- Drops of different liquids of a known volume (aqueous or organic, acidic or basic, polar or non polar, viscous, etc.) are placed onto a sample of the coated surface and incubated for a set time and temperature.
- Drops of one liquid are placed onto a sample of the coated surface at a defined temperature but at different time intervals (seconds to hours).
- Multiple samples with different surface coatings are tested.
Performing this process manually is very time-consuming. LISSY fully automates this process, with the user only having to place the labware and the substances of interest on the platform at point of run. With operation of the system permitted 24 hours a day, 7 days a week, LISSY is a true high throughput solution for surface coating R & D.
LISSY is available in various standard configurations: from 90cm up to 200cm in length and can accommodate various tubes, vials, microtitre plates, etc on its workbench. As with all Zinsser Analytic systems, LISSY, can be further enhanced with additional modules such as sample identification (barcode reading), pH-measurement and adjustment, heating and cooling stations, vortexers and stirrers and many others.
