What We Offer
Our Polysulfide technology is rapidly gaining traction in the mining and metallurgy sector due to its dual benefits of environmental remediation and metal recovery. In mining operations—especially in gold and copper extraction and in artisanal and small-scale gold mining (ASGM)—polysulfide compounds are used to stabilize and immobilize toxic heavy metals such as mercury, lead, and arsenic. This reduces their mobility and leaching potential, helping mining companies meet increasingly stringent environmental standards. Polysulfides are particularly effective in neutralizing mercury contamination, a major concern in ASGM, offering a safer, more sustainable approach to mineral processing.
Beyond remediation, polysulfide compounds also play a valuable role in metal recovery applications. They are used to selectively bind with certain metal ions, enhancing recovery from ores, tailings, and even e-waste. In gold and copper operations, polysulfides can help improve extraction yields while minimizing reliance on harsher chemicals like cyanide. Their versatility, chemical stability, and low environmental impact make them an ideal fit for mining operations aiming to increase efficiency while reducing ecological risk. As the industry continues to evolve toward greener practices, polysulfide technology stands out as a practical and scalable solution.
Polysulfides are created through the reaction of organic compounds with sulfur, forming long chains that contain multiple sulfur atoms—hence the name poly-sulfide. This molecular structure gives it unique properties, such as elasticity and resistance to chemicals and weathering.

Polysulfide forms a flexible, chemical-resistant seal that adheres strongly to most substrates. It resists fuels, oils, water, and harsh weather, making it ideal for sealing, insulating, and protecting surfaces in critical environments. Once cured, it maintains elasticity and integrity even under movement, thermal stress, or chemical exposure.

Polysulfide sealants and coatings are suitable for a wide range of applications, including concrete and metal joints, fuel and chemical storage tanks, aircraft and automotive components, marine structures, and glazing or insulating glass units. Their strong adhesion and chemical resistance make them ideal for sealing and protecting surfaces in both industrial and commercial environments.
