Iodine potassium iodide test solution is a chemical product mainly used for visualizing defects in internally coated plastic containers with coex foiling. This solution consists of denatured ethanol, aqua distillata (deionized water), iodine and potassium iodide. The chemical formula is I2-KI solution.

The chemical reactions and properties of this solution are based on the reaction of iodine and potassium iodide in the solvent ethanol and water. This produces an intensely colored solution that serves as a detection agent for defects in coated plastic containers. By applying this solution to appropriate areas, defects in the coating can be visualized as the color quickly penetrates into the defective areas.

In scientific laboratories, this test solution can be used for quantitative analysis of various samples, such as in chemistry, biology or polymer science. In particular, it can be used to check the quality and integrity of coated plastic containers commonly used for storing chemical reagents and samples.

Application of the iodine-potassium iodide test solution can provide easily interpretable results that allow rapid identification of defects or damage to internally coated plastic containers. This effectively reduces potential contamination or loss of materials and reagents.

In summary, the iodine potassium iodide test solution is mainly used to visualize defects in coated plastic containers.
