When faced with challenging lubricant needs, Dorf Ketal is here to help. We manufacture high-performance lubricants and grease component additives designed to meet the demands of modern technologies. Our additives are developed using cutting-edge platforms and are proven to perform across various types of oils, greases, and specialty lubricants.
Our lubricant component additives are engineered to enhance equipment life and reduce wear. We offer anti-wear and extreme pressure additives that bring key functionality to your lubricant formulations, protecting machinery under the toughest conditions. Our friction modifiers also help to minimize friction, leading to improved production output and increased fuel efficiency.
Objective
Control and minimize foam formation in lubricants to maintain hydraulic and lubrication efficiency.
Mode of Action
Reduce foam formation by decreasing surface tension gradients and destabilizing air bubbles in oil systems, allowing faster bubble collapse and preventing foam persistence.
