Cortec Corp. released two biobased greases from its EcoLine brand. The company’s drilling rod grease has extreme pressure additives to protect rod joints from constant vibration and reduces friction and wear. The aluminum complex-thickened grease is available in NLGI grades 1, 2 and 3 and is recommended for environmentally sensitive areas such as waterways. Cortec also released a lithium based grease for lubricating fifth wheels in semi-trucks. The grease has extreme pressure additives that reduce friction and wear, resists water washout and functions in wide operating temperatures. It can also be used in trailer hitches, mechanical joints and other parts with sliding or rolling metal-to-metal contact, the company adds. Web: www.cortecvci.com
