Coating & Laminate Tester

Coated metal and metal composite materials have enormous significance worldwide as packaging materials. This means that the manufacturers of food packaging such as cans, foils and so forth face a serious risk: if a packaging system fails at the customer, claims for damages rising to millions can easily follow.

Test the quality and stability of coatings and laminates with an easy-to-use electrochemical technique:

The IM6 or ZENNIUM Electrochemical Workstation is the heart of the COLT. The IM6 is renowned for its high precision, ease of use and comprehensive software package.

Its revolutionary SCRIPT software concept allows complex processes to be fully automated. The Script COLT controls the execution of AC measurement, DC polarisation with recovery phase and further AC measurement (AC-DC-AC) in strictly reproducible form. The reliable analysis of EIS measurements is not trivial. For this reason, COLT also carries out the comparative impedance analysis, reducing the data to well-defined, meaningful results, recording all the important parameters in a form suitable for statistical analysis, and the documentation of each individual measurement together with a printout or file export.

A cleverly devised combination of measuring cells, electrodes and auxiliary equipment, specially constructed for COLT, reduces the time needed to prepare and connect samples, allowing a high throughput of test samples.

COLT Software Option

The ZAHNER COLT measurement system has been designed to match the special demands of investigations on coatings and laminates. Besides traditional electrochemical investigations supported by the Thales software package a variety of special measurements and documentation tasks can be done easily with the COLT option:

• Layer quality test
• D-Layer test
• Delamination test
• AC-DC-AC tests on coatings & laminates
• AC-DC-AC tests on packaging materials
• AC-DC-AC tests on coated surfaces

The COLT kit consists of:

General	Coating Stability Test & Layer Quality Test	Cut Edge Delamination Test & In-Situ Can Test
COLT software module Cable sets Plastic tweezers and pipette	Shielded cylinder electrode Set of electrolyte carriers Buffer solutions	Glass vessel Stainless steel ring electrode Reference electrode Electrode stand Foil cutter
