Antifoams for Metalworking fluids

Antifoams of our Lubricant Additives segment exhibit extraordinary stability and filterability, thus providing excellent long term antifoaming properties and leading to major cost savings. They are based on either mineral oils, vegetable oils, silicone oils or organomodified siloxanes (OMS), which are our core competence.   

While organic antifoams show excellent compatibility but moderate efficiency, silicone-oil based antifoams offer high efficiency with often poor compatibility. Our specialty antifoams based on OMS provide the best of these two worlds - high compatibility combined with excellent performance. As an example, organomodified siloxane-based antifoams do not cause any detrimental effects in the finishing processes of treated parts, which are typical for silicone oil-containing antifoams.

In our regional competence centers we are able to design the properties of antifoams, such as compatibility and efficiency (function of surface activity), in order to meet your specific requirements. Long term stability of antifoams in metalworking fluid formulations must be achieved in order to minimize the addition of tank side antifoams.
