Ingevity’s Diacid 1550™ emulsifier simplifies jet engine manufacturing


NORTH CHARLESTON, S.C., September 19, 2018 – The benefits of Ingevity’s Diacid 1550 pine-based emulsifier for metalworking fluid formulators are highlighted in a recently released video. The video, available on Ingevity’s YouTube channel, focuses on Protomatic, Inc., a Michigan-based manufacturer of space vehicle components for Blue Origin. Protomatic uses Diacid 1550 in the coolant formulation used to machine high-performance super alloy metals required in today’s jet and rocket engines.

Diacid 1550 is an environmentally friendly emulsifier that is increasingly being used by metalworking fluid formulators worldwide. Its unique dual-action functionality – the ability to create a more stable metalworking fluid and inhibit corrosion – reduces the amount of emulsifier additives required in a machining coolant, which saves formulators money.

“The super alloy metals we use to make these massive rocket engines are more difficult to cut,” explained Doug Wetzel, vice president and general manager at Protomatic. “They also require higher heat, pressure and lubricity in order to be cut with the desired precision. We use Diacid 1550 in our coolant formulation when machining super alloys because it works well in this harsh environment.”
