It all starts with Hopewell. AdvanSix Hopewell has grown from making gun cotton for allies in WWI to being one of the world’s largest single manufacturing sites for ammonium sulfate, which makes the fertilizer that helps grow crops around the world possible. It is also one of the world’s largest single manufacturing sites for caprolactam, which is used to make Nylon 6 resin – a key ingredient in the carpet under your feet. Hopewell is the largest manufacturing site in the AdvanSix enterprise and through our commitment to safe, stable and sustainable operations as well as our amazing team and what they bring, we have made a lasting impact on Virginia manufacturing. AdvanSix is proud to be active in the Hopewell community and serve as good environmental stewards.

AdvanSix Methyl Ethyl Ketoxime (MEKO)


Methyl ethyl ketoxime (MEKO) is a high-efficiency anti-skinning agent used for air-drying paints, inks and coatings. It is also used to improve the shelf life of silicone adhesives and sealants, and the functionality of polyurethane coatings. MEKO is produced to meet the low moisture and high assay standards that formulators require.



EZ-Blox® offers a safe, cost-effective and proven alternative to MEKO. It is designed to optimize the performance of alkyd-based paint systems by preventing a surface skin from forming when the product comes into contact with atmospheric oxygen. This, in turn, improves paint performance and reduces waste. contact with

Nadone® HDR® Cyclohexanone


Nadone® HDR® cyclohexanone is ideal in applications that are sensitive to oxygen or peroxide. Key benefits include: uniform evaporation, minimal moisture content, low toxicity and ecotoxicity, low volatile organic compounds (VOCs), and a good cleaning solvency. Applications range from agricultural pesticide formulations, paints and coatings to electronics, PVC adhesives and printing ink formulations.

Naxol® Cyclohexanol


Naxol® cyclohexanol is ideal for applications sensitive to oxygen or peroxide. These range from agricultural products and rubber to plasticizers and solvents to flavors and fragarances. Naxol® cyclohexanol has a low toxicity and ecotoxicity profile, and is produced to low moisture standards.

Sulf-N Ammonium Sulfate


AdvanSix Sulf-N® ammonium sulfate (21-0-0-24S) is a high-analysis fertilizer that provides efficient nitrogen and readily-available sulfur to crops. It is available in granular, mid and soluble sizes.
