Frequently Asked Questions
• What makes Cortec S-8 stand out from other corrosion inhibitors on the market?
Cortec S-8 truly shines because it's specifically formulated with ingredients recognized by the FDA, ensuring its suitability for sensitive applications. Unlike many other other inhibitors, it offers remarkable corrosion protection even at very low concentrations, performing effectively both underwater and at the critical air/water interface. Plus, it forms a thin, non-sticky protective layer, which is a real bonus for machinery and finished products.
• How does Cortec S-8 actually protect metals from rust and corrosion?
This intelligent product works by depositing a unique, non-toxic "green" filming corrosion inhibitor that creates a stable, protective barrier on metal surfaces. It also includes a Vapor phase Corrosion Inhibitor (VpCI) which releases molecules into the air, reaching all metal surfaces within an enclosed space, even those not directly in contact with the liquid. This multi-phase protection ensures comprehensive coverage against corrosive elements.
• Is Cortec S-8 considered an environmentally friendly or "green" product?
Absolutely! Cortec S-8 is indeed a "green" solution, as it's formulated with FDA-listed ingredients and boasts a 71% USDA certified biobased content. This means it relies on renewable raw materials, reducing dependence on petroleum-based products, and it's even part of the USDA BioPreferred® Program, highlighting its commitment to sustainability.
• Can I use Cortec S-8 with my existing water treatment chemicals?
Yes, you can! Cortec S-8 is designed to be highly compatible with the majority of water chemistries and other products typically used in water treatment systems. This flexibility allows for seamless integration into your current processes without compatibility concerns.
• What is the primary application for Cortec S-8?
Cortec S-8 is particularly effective and widely used for the corrosion protection of packed metallic food cans, specifically during the washing and sterilization stages of the food processing industry. It helps prevent "flash rust" that can occur from exposure to steam and water.
Relevant products you may want to consider:
• Beyond food cans, are there any other metal items that can benefit from Cortec S-8's protection?
While its main focus is on food cans, any metallic components that undergo washing or sterilization processes and require a non-toxic, FDA-compliant corrosion inhibitor could potentially benefit from Cortec S-8, especially where sticky deposits are undesirable.
• How does S-8 help prevent corrosion during the high-temperature sterilization process of food cans?
During the hot steam sterilization of food cans, metal surfaces are highly susceptible to flash corrosion. Cortec S-8 acts in three crucial phases – in the water, in the air (through its VpCI action), and at the air-water interface. This comprehensive action ensures that even when cans aren't fully submerged, they are protected from corrosive elements like steam and oxygen.
• Will Cortec S-8 leave any residue or sticky film on the treated surfaces?
No, that's one of its standout features! Cortec S-8 is specifically engineered to leave behind a thin, protective layer that is non-sticky and will not cause any undesirable deposits on the surface of the treated cans or other metallic items.
• Can Cortec S-8 be used in both hot and cold water applications during processing?
Yes, Cortec S-8 demonstrates excellent film persistency and stability across a wide temperature range, making it effective for use in both hot steam sterilization and subsequent cold-water bath applications during processing.
• What's the recommended dosage for Cortec S-8 when treating water?
For optimal performance, Cortec S-8 should be added continuously to the process water at a concentration level ranging from 150 to 250 parts per million (ppm).
Relevant products you may want to consider:
• Do I need to continuously add Cortec S-8, or is it a one-time treatment?
For consistent and effective protection, it's recommended to add Cortec S-8 continuously to the water system. This ensures that the corrosion inhibiting properties are maintained throughout the washing or sterilization process.
• Is there any special surface preparation required before using Cortec S-8?
The information suggests that Cortec S-8 can be effectively incorporated into existing washing and sterilization processes. No specific additional surface preparation is generally mentioned as being required for its application; it's designed to integrate seamlessly.
• Will Cortec S-8 interfere with other cleaning or processing steps in the production line?
Cortec S-8 is designed to be compatible with most water chemistries and processes, and its non-sticky film prevents interference with subsequent production steps. It's an additive meant to enhance the protection without disrupting the overall workflow.
• Is it complicated to implement Cortec S-8 into an existing food can production facility?
Not at all. Cortec S-8 is formulated as an additive that can be introduced at a very low dose into the sterilization and cooling water. This makes its integration into existing food can production lines relatively straightforward, as demonstrated by real-world applications.
• What are the key ingredients that make up Cortec S-8?
