Drewcor™ corrosion inhibitors
Drewcor corrosion inhibitors include a family of concentrated products used in boiler condensate systems to effectively control corrosion caused by low pH and dissolved oxygen. Drewcor products are formulated by blending neutralizing amines with one of Ashland’s patented Mekor™ corrosion inhibitor products. The resulting synergistic
formulations passivate metal surfaces, making them corrosion resistant to all sources of condensate corrosion. Additionally, the passivation allows for the easy removal of soluble iron and copper from the system by continuous blowdown.

Corrosion Monitoring and Metallurgy
Problems related to corrosion cost commercial and industrial plants billions of dollars each year. Although a variety of means exist to inhibit corrosion, it's important to identify the root cause of the corrosion. Ashland Water Technologies’ Corrosion Monitoring and Metallurgy group provides failure analysis and assessments of steam-generating and heat-exchanger equipment. Working closely with customers, this team provides clear identification of the problem, which leads to a more rapid and effective solution. Key services provided by the group include failure analysis, corrosion coupon analysis, and elemental and compound analysis.
Water Process Applications
Ashland Water Technologies’ Water Process Applications team is dedicated to helping customers improve the performance of their boiler, heating and cooling systems, and associated processes. The team supports customers worldwide from four technical centers that house extensive analytical capabilities and innovative process testing instrumentation. Using both laboratory bench and pilot scale equipment, the team can evaluate chemical and mechanical treatments and explore “what-if” scenarios under actual-use conditions. The hard data and insights gained during these evaluations allow Ashland to confidently recommend treatment strategies that ensure system efficiency.
