Clariant recently announced that its new Hostacor AL corrosion inhibitor has been recognized by the U.S. Environmental Protection Agency (EPA) for its potential to reduce environmental pollution. The recognition is part of the EPA's Pollution Prevention (P2) Recognition Project within its New Chemicals Program (NCP), which is intended to encourage chemical companies to develop greener chemistries.

Designed for use in the metalworking industry, Hostacor AL contains no phosphorus but is entirely based on renewable feedstocks. It can inhibit corrosion on steel and aluminum surfaces at low concentrations and pH values of around 9. The water-dispersible corrosion inhibitor also contributes to the lubrication of both metals.

When used in aluminum cutting operations, Hostacor AL provides protection against staining in soft and hard water, produces no lime soaps and has a very low foaming tendency. An additional benefit is that existing metalworking fluids for steel can be upgraded to machine aluminum by post-adding Hostacor AL to the formulation.

"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 lightweight materials," said Ralf Zerrer, head of strategic marketing and innovation at Clariant. "This is mainly driven by the demand from the automotive or aviation industry to reduce weight and increase energy and fuel efficiency. Hostacor AL has an outstanding combination of excellent performance in terms of corrosion prevention and lubrication, together with high sustainability."
