Fully Synthetic Compound Concentrate FS600

For metalworking fluid formulators seeking cost-effective water-based coolant raw materials, many conventional synthetic compound raw materials suffer poor hard water tolerance, slow defoaming speed and insufficient long-term rust protection for ferrous workpieces. ROLITOM RLT-FS600 fully synthetic compound concentrate is custom engineered to resolve these common formulation pain points for grinding and cutting fluid production.

This integrated raw material is compounded with premium boundary lubrication additives, ferrous rust prevention agents and multi-metal anti-corrosion inhibitors. Fluid manufacturers only need to mix this concentrate with clean tap water under normal temperature to produce finished synthetic metalworking fluid with balanced comprehensive performance. The whole formulation system excludes restricted hazardous substances including heavy metal compounds, sodium nitrite and phenols, fully matching global industrial environmental control regulations for workshop production and wastewater discharge.

After simple water dilution, the finished synthetic coolant delivers stable cooling capacity, rapid defoaming response, robust lubricating property and long-lasting anti-rust protection. It fits continuous mass machining of cast iron, carbon steel and alloy steel in CNC centers, grinding machines and automated production lines.

Product Advantages

1. All-round balanced machining performance for synthetic coolant

   Coolants blended with RLT-FS600 integrate four core functions: rapid heat dissipation during cutting, boundary friction lubrication, workpiece surface cleaning and long-term ferrous corrosion prevention, covering turning, milling, drilling and surface grinding procedures.

2. Excellent long-term dilution system stability

   The water-soluble formula avoids stratification, sediment or flocculation after long-term storage of diluted working fluid, greatly reducing fluid replacement frequency and cutting operating costs for downstream machining plants.

3. Extend cutting tool service life & upgrade workpiece surface finish

   A uniform protective lubricating film forms between cutter edge and metal blank during high-speed material removal, lowering abrasive wear of carbide and high-speed steel tools while eliminating micro-scratches and surface burrs on finished parts.

4. Outstanding hard water adaptability

   Specially modified chelating components resist mineral ions in medium/hard industrial tap water, preventing scale precipitation and performance attenuation caused by hard water contamination of coolant tanks.

5. Fast defoaming characteristic for high-pressure circulation equipment

   Low-foam molecular design suppresses foam generation under large-flow coolant circulation, and residual foam collapses instantly without overflowing tanks or blocking filter cartridges in 24-hour non-stop production.

6. Eco-friendly formula with easy spent fluid disposal

   No toxic restricted raw materials are added to the concentrate. Waste synthetic coolant can be processed via standard industrial wastewater facilities without complicated hazardous waste treatment procedures.

Typical Physical & Chemical Performance Indexes

Applicable Machining Materials

Synthetic coolants produced from RLT-FS600 fully synthetic compound concentrate are compatible with all mainstream ferrous metal substrates for general metal removal processes, including:

• Medium / low carbon steel

• Alloy structural steel

Standard Batching & Operation Guidance

1. Concentrate Blending Steps

Prepare clean tap water at ambient temperature first, then add RLT-FS600 fully synthetic compound concentrate proportionally while activating circulation stirring equipment. Stop mixing once the mixed liquid turns fully clear and transparent, which becomes the finished synthetic coolant stock solution for factory sales or on-site dilution.

2. Recommended Factory Batching Ratio

Mix RLT-FS600 concentrate with tap water at a proportion range of 45% ~ 55% concentrate to 45% ~ 55% water to make stable synthetic coolant stock concentrate. End machining workshops shall further dilute this stock solution to 5% mass fraction with water for actual CNC machining deployment.

Packaging, Storage & Shelf Life

Available Packaging Specifications

20L plastic drum, 200L steel drum, 1000L IBC tote tank bulk supply available for mass order. Customized packaging plans can be arranged according to annual factory output.

Storage Requirements

Store unopened sealed barrels indoors in dry, ventilated warehouses, far away from direct sunlight and high-temperature heat sources such as boilers. Tighten barrel lids completely after partial material extraction to stop moisture, dust and workshop impurities from contaminating the concentrate.

Shelf Life 

Unopened original sealed RLT-FS600 barrels stored under compliant warehouse conditions carry a 12-month shelf life counted from production date. We recommend full consumption within 3 months once barrel sealing is broken to retain complete lubrication and anti-corrosion activity.

FAQ

Q1: What is the standard mixing ratio for mass production of general-purpose fully synthetic cutting fluid with RLT-FS600?

A1: The mainstream batching scheme adopted by most coolant factories is 50% RLT-FS600 compound concentrate mixed with 50% tap water, which balances raw material cost, refractive index testing convenience and full set Grade A anti-rust performance for multi-metals.

Q2: Can RLT-FS600 be blended with semi-synthetic additive packages or other brands of synthetic concentrates?

A2: Cross-formula mixing is strictly forbidden. Mismatched emulsifiers, rust inhibitors and defoaming components will trigger chemical reactions, resulting in severe foaming, liquid stratification and complete failure of metal corrosion protection performance.

Q3: Does RLT-FS600 diluted coolant still work stably in hard water machining workshops?

A3: Yes, the formula adds dedicated water softening chelating agents to offset mineral ions in hard tap water, avoiding scale precipitation and filter clogging common with ordinary synthetic coolant concentrates.

Q4: What metal anti-corrosion grade can coolants made from RLT-FS600 reach under GB/T6144 standard?

A4: All cast iron, red copper and LY12 aluminum alloy test items pass Grade A corrosion resistance standard, meeting the highest industrial requirement of China synthetic cutting fluid national standard.

Q5: Is RLT-FS600 suitable for aluminum alloy mass machining?

A5: It can provide basic 8-hour anti-tarnish protection for LY12 aluminum under constant temperature test; for long-term continuous aluminum processing, we suggest matching professional aluminum anti-discoloration auxiliary additives to eliminate white oxidation haze.
