Clariant gains preliminary EPA recognition for pollution prevention potential of Hostacor® AL corrosion inhibitor
- Water-dispersible corrosion inhibitor contains no phosphorus, is 100% derived from renewable feedstocks
- Effective corrosion protection of both steel and aluminum while contributing to lubrication
- Component awarded EcoTain® label for its sustainable excellence profile
Unlike other corrosion inhibitors on the market, Hostacor AL contains no phosphorus, a potential nutrition source for microorganisms. Hostacor AL is entirely based on renewable feedstocks.
Hostacor AL inhibits corrosion on steel and aluminum surfaces at low concentrations (well under 2.0%) and pH values of around 9. At the same time, the component contributes to the lubrication of both metals. When used in aluminum cutting operations, it provides protection against staining in soft and hard water. It produces no lime soaps and has a very low foaming tendency. An additional benefit is that existing metal working fluids for steel can be upgraded to machine aluminum by post-adding Hostacor AL to the formulation.
Since the beginning of this year, Hostacor AL has been carrying Clariant's EcoTain® label, in recognition of its high level of sustainability. Products can only obtain the EcoTain label after they have undergone a systematic, in-depth screening process using 36 criteria in all three sustainability dimensions: social, environmental and economic. EcoTain label awarded products significantly exceed sustainability market standards, have best-in-class performance and contribute to sustainability efforts of Clariant and its customers.
Visitors to STLE 2016, the annual meeting of the Society of Tribologists and Lubrication Engineers in Las Vegas on May 16-18, will be able to hear more from Clariant about some of the latest developments in water dispersible corrosion inhibitors for aluminum cutting fluids. Andy Michael, Technical Manager for Industrial Lubricants of Industrial & Consumer Specialties, is scheduled to give a lecture on the subject on Tuesday, May 17 at 2 p.m..
"There is a growing need in the metalworking industry for sustainable and multi-functional additives, especially for use in semisynthetic-based cutting and grinding fluids that are intended to machine light-weight materials. This is mainly driven by the demand from the automotive or aviation industry to reduce weight and increase energy and fuel efficiency.", says Ralf Zerrer, Head of Strategic Marketing & Innovation at Clariant's Business Unit Industrial & Consumer Specialties. "Hostacor AL has an outstanding combination of excellent performance in terms of corrosion prevention and lubrication, together with high sustainability."
