Anti-Foaming Agents

Anti-foaming Agents or defoamers are additives that are used to prevent or limit the formation of foams and useful in applications where the oil may be exposed to contaminants or over aeration during normal operation which can result in foam formation.

Product Description BenefitsApplications
Liofoam®
148
Liofoam®
148 is an antifoam.
Anti-foaming agent based on mineral oil, emulsifiers and amides indicated for soluble cutting oil formulations. In addition to total efficiency of foam breakdown and excessive formation. Exceptional resistance to pH variations of the emulsion. Formulation of emulsifier packages for soluble oils based on a blend of surfactants and hydrophobic particles in mineral oil.
OLOA® 4900COLOA® 4900C is a Ashless, zinc free, multifunctional additive.Prevents or minimises wear in circumstances where the lubricant film thickness has degraded such as decrease in viscosity (e.g. due to temperature increase), reduction in speed and increase in bearing load. Reduces foam formation in lubricants, which can impair lubrication and cooling in hydraulic systems.For hydraulic, gears and slideways applications.
Viscoplex® 14-520Viscoplex® 14-520 is a Anti-foam
Additive.
VISCOPLEX® 14-520 is a soluble type of anti-foam for oil based lubricants . Particularly good in maintaining demulsion performance over extended time and for having minimal impact on air release nd other properties. Maximum dosage 400ppm. Often employed as a ‘problem solver’ where conventional anti-foam additives have failed
