polyalkylene glycol chemistry. One of these is a novel triblock configuration. Unlike more commonly used configurations, triblock copolymers of polyalkylene glycols exhibit a distinct ability to attract and sequester water. And unlike other lubricant additive technologies, triblock copolymers are made from readily available building blocks for a cost-effective option that improves performance.
Acting essentially as a polymeric sponge, they render water inert, helping to prevent the esters from interfacing with intrusive water or moisture and thereby preserving the integrity of the ester. This ability to help protect lubricant quality is amplified by the fact that these stabilisers can also control deposits, reducing any residue that may otherwise form as esters degrade and can extend the performance life of the lubricant.
Currently, two UCON™ WaterGuard Stabilizer options are available. UCON WG-1 stabilizer can be used with most natural and synthetic esters, including unsaturated and saturated synthetic esters. UCON WG-2 stabilizer is intended for use primarily with saturated synthetic esters. Both grades are readily biodegradable as defined by OECD 301F. A further product is also under development.
Natural and synthetic esters offer important environmental benefits when formulating modern EALs for marine applications. And lubricants used in these water-prone environments are critical to ensuring equipment reliability and longevity. With the introduction of UCON™ WaterGuard Stabilizers, comprising a small percentage of lubricant formulations, ester-based lubricants can be formulated for longer service life while contributing to more sustainable commercial marine shipping.
