RLT-F30 is an advanced cutting fluid specially formulated for CNC machining centers, multi-function machine tools, and centralized cooling systems. Free from sulfur and sodium nitrite, it delivers exceptional lubrication, rust prevention, cooling, and extreme pressure (EP) performance for machining ferrous metals, copper, and aluminum alloys.

RLT-F30 is a high-performance semi-synthetic micro-emulsion metalworking coolant built for heavy-duty industrial metal cutting processes. The product adopts premium extreme pressure EP additives, high-efficiency anti-corrosion inhibitors and special composite lubricants as core raw materials, with a low-risk formula that excludes sulfur and sodium nitrite.
This micro-emulsion coolant effectively reduces chemical staining on finished workpieces and lowers skin irritation risks for frontline operators. The built-in stable biocide formula inhibits bacterial and fungal reproduction inside the cooling tank, greatly extending the service cycle of the working fluid and cutting the frequent replacement cost of coolant for machining factories.
Balancing cooling efficiency, lubricating performance, rust prevention and heavy-load extreme pressure performance all in one, RLT-F30 matches all mainstream CNC machining equipment and centralized cooling circulation systems. It can cover turning, drilling, milling, grinding and other cutting processes for ferrous metals, copper and aluminum alloy materials.
Core Advantages of ROLITOM RLT-F30
Strong extreme pressure lubricating performance can lower cutting friction between tools and blanks, reduce tool wear and workpiece burrs, upgrade finished surface smoothness and prolong tool service life.
Excellent biological stability avoids odor generation caused by microbial deterioration and extends the service cycle of liquid in the machine sump.Dual anti-rust and anti-tarnish protection works for both ferrous metals and non-ferrous metals including copper and aluminum, preventing surface oxidation and discoloration during processing and storage.
Low fluid carry-off rate keeps the working concentration stable for a long time, effectively cutting the overall production cost of metal processing plants.
High detergency quickly washes away metal chips, floating waste oil and processing residues, maintaining the cleanliness of the cooling tank and reducing manual cleaning frequency.Safe low-hazard formula without sulfur and sodium nitrite, mild contact with human skin, lowering occupational health risks for workshop workers.

Mixing & On-site Operation Standards
Standard dilution ratio for daily production is 1:20
Operation steps for liquid preparation: Inject clean water into the machine cooling tank first, start the circulating pump, then slowly add RLT-F30 concentrated coolant to achieve uniform mixing.Production management suggestions: Regularly detect the concentration and pH value of working fluid; supplement pure concentrate when the concentration is lower than the standard range. Clean metal chips, floating waste oil and sediment at fixed intervals to maintain long-term stability of the coolant.

FAQ
Q1: What metal materials can ROLITOM RLT-F30 micro-emulsion coolant process?
A1: It supports carbon steel, alloy steel, cast iron, copper and all aluminum alloys. It cannot be used for magnesium alloy processing, which will cause chemical reactions and material damage.
Q2: What dilution ratio should factories use for daily CNC machining?
A2: The universal standard mixing ratio is 1:20. Adjust the concentration appropriately according to heavy cutting or fine grinding working conditions.
Q3: Does this coolant contain sulfur or sodium nitrite harmful to workers?
A3: RLT-F30 adopts sulfur-free and sodium nitrite-free formula, mild to human skin, reduces workshop occupational health risks and avoids workpiece surface chemical discoloration.
Q4: How long is the service life of the coolant in the machine sump?
A4: With advanced biostable formula, it inhibits bacteria and mold growth, effectively extending sump service life and reducing the frequency of coolant replacement.
Q5: What packaging options are available for bulk factory orders?
A5: We supply 20L plastic small barrels and 200L iron large drums to meet small workshop and large factory bulk purchase demands.
Q6: How to store unused concentrated coolant to avoid performance failure?
A6: Store indoors at 5°C-35°C, avoid sunlight and high temperature; keep barrel lids sealed to prevent rainwater and impurities from entering the liquid.
Q7: Can RLT-F30 match centralized cooling circulation systems for large production lines?
A7: Yes, this micro-emulsion coolant is fully compatible with single CNC equipment and factory-wide centralized cooling circulation systems for mass production.
