BP’s lubricant subsidiary Castrol launched Hysol SL 37 XBB, a semi-synthetic soluble cutting fluid for steel and aluminum alloy machining operations. The fluid is boron-, chlorine- and formaldehyde-free and can reduce biocide additive top-ups by up to 90 percent, leading to longer fluid life, the company says. The fluid is suitable for soft- and hard-water regions and is non-irritating to skin in a 20 percent emulsion. Castrol also launched a new wind turbine lubricant, Tribol GR SW 460-1. It claims that the product creates a stable lubricant film that becomes even more pressure resistant with increasing load, and resists shearing, wear and water ingress. Web: www.castrol.com
