RLT-230P is a high-performance emulsified soluble oil additive package formulated with premium rust inhibitors,emulsifiers,extreme pressure lubricants,and specialty amines.
Designed for ferrous metal machining, it delivers exceptional rust resistance, emulsion stability, and cleaning performance—ideal for die steel, high-carbon steel, 45# steel, cast iron, and stainless steel.

ROLITOM RLT-230P is a multi-functional all-in-one emulsifier additive package specially customized for manufacturers producing paraffinic soluble metalworking oils. It is compounded with premium composite rust inhibitors, matched anionic & nonionic emulsifiers, heavy-duty extreme pressure lubricants and special amine components to simplify your cutting oil blending workflow.
After mixing this additive package with 150SN / 150N paraffinic base oil, the finished soluble oil obtains stable emulsification performance, outstanding long-term anti-rust ability, strong cleaning power and excellent hard water tolerance. The blended cutting fluid targets full ferrous metal machining scenarios, covering die steel, high carbon steel, 45# medium carbon steel, cast iron and stainless steel for general metal cutting production lines.
Performance Advantages
Strong universal emulsifying power, fully compatible with mainstream 150SN and 150N paraffinic base oils, easy to form uniform transparent soluble oil concentrates under normal temperature stirring.
Composite multi-stage anti-corrosion formula provides reliable inter-process rust protection for ferrous metal workpieces, effectively avoiding rust stains during production intervals.
Balanced compound surfactant system combines anionic and nonionic emulsifiers, locking long-term emulsion stability and preventing oil stratification during long-term storage of finished soluble oil.
Excellent hard water resistance property, no oil separation or soap precipitate generation even when diluted with high-hardness industrial water, stable processing performance all year round.
Built-in low-foam formula restricts foam accumulation under high-flow pump circulation, eliminates foam overflow interference on automatic CNC machining production lines.
Safe clean formulation without nitrites, phenols, chlorine and harmful primary amines, meeting global environmental protection standards and lowering workshop occupational health risks.

Recommended Blending Formula Ratio
Standard Production Mixing Proportion
Blend 17 ~ 23 wt% RLT-230P additive package with 77 ~ 83 wt% 150SN / 150N paraffinic base oil at room temperature. Keep stirring continuously until the mixture turns into fully homogeneous transparent soluble oil concentrate.
Pre-Production Trial Reminder
Different batches and grades of paraffinic base oil have varying emulsification compatibility. All customers must complete small laboratory compatibility tests before large-scale mass blending, to confirm stable emulsification and consistent performance of finished soluble oil.
Product Application Scope
Finished soluble oil formulated with RLT-230P additive package supports all common ferrous metal cutting processes: turning, drilling, boring, milling, tapping and general metal removal machining.
Applicable Workpiece Materials: Die steel, high-carbon steel, 45# medium carbon steel, cast iron, stainless steel and other ferrous alloys.
FAQ
Q1 What base oil is RLT-230P additive package compatible with?
A1 It is specially developed for 150SN and 150N paraffinic base oils, stable emulsification can be achieved with the recommended mixing ratio. Small lab trials are required if you use other base oil grades.
Q2 What mixing ratio should I use for mass production of soluble cutting oil?
A2 The standard formula range is 17%–23% RLT-230P matched with 77%–83% paraffinic base oil, stir at room temperature until completely transparent and uniform.
Q3 Is this additive free of chlorine, nitrite and other harmful substances?
A3 Yes, RLT-230P formula excludes nitrites, phenols, chlorine and harmful primary amines, complying with international environmental and occupational safety standards for metalworking fluid raw materials.
Q4 What metal materials can the finished soluble oil process?
A4 The blended cutting oil is only suitable for ferrous metals including die steel, high-carbon steel, 45# steel, cast iron and stainless steel; not recommended for aluminum, copper and other non-ferrous alloys.
Q5 Does the finished soluble oil produce excessive foam under high-flow pump circulation?
A5 The additive package has inherent low-foam characteristics, foam volume stays 0ml within 10 minutes under lab foam testing, no overflow issues for high-speed CNC production lines.
Q6 What packaging options can I order for bulk raw material procurement?
A6 Standard packages are 200L steel drums and 1000L IBC totes; we support customized special packaging for large long-term factory orders.
Q7 How long is the shelf life of unopened RLT-230P additive package?
A7 Unsealed original drums stored in cool dry indoor warehouses have a 12-month shelf life.
Q8 Do I need to do small trial blending before mass production?
A8 Definitely required. Different batches of paraffinic base oil have different emulsification compatibility; lab small-scale tests help avoid unstable finished oil and mass production losses
