Combating foam in industrial lubricants especially in enclosed systems for gear and hydraulic oils poses special challenges. BYK’s new line of defoamers tailor-made for oil based industrial oils can help. Most lubricant applications involve agitation trapping air in the oil which can lead to the formation of foam. Foam can not only create a mess and a safety hazard if it spills out onto the floor, but it can lead to poor performance. Because foam does not pump or circulate, it reduces the overall effectiveness of a lubricant. This can result in overheating, accelerated wear, oxidation, and overall failure of a gear or hydraulic oil.
BYK has launched a new series of defoamers specifically for oil based industrial lubricants; BYK-9730, based on polymer and silicone, is a versatile defoamer for all commonly used base oils, BYK-9731, a silicone free polymeric defoamer for certain systems and BYK-9732, a cost-effective silicone defoamer for certain systems where transparency isn’t critical.
