Subsea Underwater Hyperbaric Welding Chemicals for Subsea Applications

Premier Chemicals are the trusted supplier of choice due to their high quality products. They can provide you with everything you may need, from chemicals to catalysts, for subsea underwater hyperbaric welding.

Our NanAuCat gold based oxidation catalyst is manufactured by 3M and has been specifically developed for the removal of carbon monoxide (CO) from gas streams, through converting the carbon monoxide to carbon dioxide (CO₂).

The NanAuCat™ catalyst is widely used in hyperbaric subsea underwater welding applications to remove carbon monoxide generated during the welding process. NanAuCat™ demonstrates significantly higher activity compared with traditional Pt based catalysts offering a significant cost saving combined with higher efficiency.
