Clariant Introduces New Generation Phosphate Ester

Clariant, one of the leading suppliers of sustainable components and solutions for the Industrial Lubricants segment, has launched a new and innovative phosphate ester that delivers high performance and sustainability in metal processing fluid formulations. Extremely low foaming profile combined with high-pressure performance and strong emulsification properties come together in Hostaphat 1738. The product can be incorporated into semi-synthetic, synthetic, soluble oil and straight oil formulations, and its ease of use in such diverse metal processing formulations positions it among the top choices of formulators and production managers.

"Contains lower phosphorus content compared to standard phosphate esters"

Hostaphat 1738 also offers superior sustainability properties. Thanks to the natural alcohols used, the component, which is 50% produced from biological sources, contains significantly lower phosphorus content compared to standard phosphate esters. Jeff McManus, Business Director of Industrial and Consumer Specialties for Clariant North America, commented on the subject: "The theory that using more material is better holds validity in our industry, based on the assumption that an ester requires higher phosphorus content to achieve better performance in terms of lubricity. With Hostaphat 1738, we have demonstrated that this is not the case by achieving the same performance as esters with higher phosphorus content that could harm machinery and the environment." The product development team worked with Clariant's low-foaming surfactant series to further develop these chemical properties so they function as an extreme pressure additive that enhances the performance of emulsifiers. This provides an additional solution enabling metal processing fluid manufacturers and formula producers to improve lubricity, emulsion stability and performance through a single multifunctional product. Jeff McManus further stated: "Hostaphat 1738 delivers benefits throughout the entire lifecycle of metal processing fluid. Reduction of foam helps increase efficiency while the stabilization of the component extends the service life of the material. When processing and disposal time comes, reduced phosphorus content means reduced environmental impact. In this way, positive effects on performance and sustainability are achieved from the beginning to the end of the product's service life."
