Steamate PAS6055 is a blend of a multifunctional, volatile amine corrosion inhibitor (the “Polyamine” component) and a specific blend of neutralizing amines selected for effective coverage of complex steam distribution systems.
Steamate PAS6055 protects metal surfaces from corrosion via multiple mechanisms. The volatile polyamine corrosion inhibitor forms a barrier film on all metal surfaces (Figure 1). Thus, the deaerator, feedwater piping, boiler, steam piping, and condensate return piping are all protected from oxygen and carbonic acid corrosion. The product also contains a blend of neutralizing amines, which can neutralize acidic contaminants and elevate the pH of the condensate into the mildly alkaline range, where the protective metal oxides are most stable and adherent.
Additionally, surface active chemistry provides dispersant qualities to help maintain clean heat transfer surfaces.

The patented Boiler Terpolymer (BTP) included in the PAS6055 provides highly effective control of boiler hardness and iron contamination.
Improved corrosion control reduces the potential for boiler tube failures by reducing the level of corrosion product ingress from the steam condensate and feedwater circuits and the resulting metal oxide deposition on internal boiler heat transfer surfaces. It also maintains optimum fuel-to-steam efficiency by maintaining clean heat transfer surfaces and minimizes disruptive outages and maintenance costs associated with corrosion-related failures of steam condensate and feedwater piping, economizers, condensers and other heat exchangers, steam traps, and other associated equipment.

Steamate PAS6055 is designed for application to steam boilers. This technology is not approved for use where the steam contacts food products or is used for direct humidification of indoor air.
Treatment and Feeding Requirements
Proper treatment levels for Steamate PAS6055 depend on many factors particular to a given application. Although the condensate pH is usually maintained in a mildly alkaline range, the product should be used in accordance with control procedures that Veolia establishes for a specific application. Boiler feedwater containing Steamate PAS6055 may not be injected into steam for attemperation because of the Solus polymeric dispersant included in the product.
Physical and Chemical Properties
Typical physical and chemical properties are shown on the Safety Data Sheet, a copy of which is available on request.
In some cases, a thin waxy layer may appear on top of the product, or the product may look hazy. The thin layer is easily dispersed by mixing and the product becomes clear when heated to 41°C (do not heat above 50°C). The presence of the thin layer or the haziness will not adversely affect the product’s performance.
Steamate PAS6055 is a liquid blend supplied in a variety of consumer packages.
Store Steamate PAS6055 at moderate temperatures in a ventilated location and protect from freezing.
