Q. Does VCI effect plastics, rubbers, wood or other non-metallic surfaces? BENZ Packaging has never been contacted regarding an issue with VCI compatibility to Non-Metallic Surfaces such as Plastics, Rubbers or Wood. However, since there are so many possible combinations of ingredients, processes and types of these Substrates it is impossible to guarantee anything regarding their suitability with VCI. Other Rust Prevention process such as Oils, Greases and other liquid RPs (Rust Preventatives) pose a much higher likelihood of reacting with Plastics, Rubbers and Wood. However, it is important for each customer to check VCI Compatibility with our experts at BENZ Packaging with these substances due to the complexity and number of plastics, rubber materials and woods in the marketplace.
