Advanced Filming Amine for Seawater Biofouling Control! Mexel 432 is a highly effective filming amine with dispersant and detergent action, designed to control seawater biofouling. It also acts as a mild biocide at sub-lethal doses, providing comprehensive treatment for corrosion, scaling, sedimentation, and biofouling. Mexel 432 creates a molecular layer on the inside surfaces of the system, preventing and remediating fouling over time. Available in Australia only.

Directions for use
Mexel 432 has been specially developed to prevent and minimized seawater biofouling. The dispersant/detergent in the product effective prevent and remediate biofouling overtime. The key mechanism is through dispersant and detergent action to remove biofilm formation, therefore minimize the colonisation of such organisms on metal surfaces. The filming characteristics will also provide corrosion and scale control properties. Mexel 432 can be used in both static and flowing systems. Some application examples are: sea water systems, including seawater intakes; filter boxes and piping; static ballast tanks; stability trimming tanks and oil rig sea legs.
Dosage and control For Sea Water Cooling Systems Dose 0.6 litre of Mexel 432 for every 100 tons of sea water flowing through the system per 30 mins. The system throughput is either to be determined from the rating of the pump(s) or from the system specifications. The calculated dose should be dosed at a 30 mins duration per day.
Dosing Method The diagram attached shows a typical dosage layout. This can be modified to suit a particular situation. A chemical dosing pump, with or without alarm to be used. Although the product will gradually clean fouled systems, treatment should preferably be started with a clean system. The product can be dosed neat or if necessary diluted into fresh water to accommodate the dosing equipment. When changing over from any other product to Mexel 432, flush the entire dosing system thoroughly with fresh water.
