Fully Synthetic Cutting Fluid Additive Package FS700

RLT-FS700 is a fully synthetic cutting fluid additive package developed for water-based MetalWorking Fluids used in industrial cutting operations. The formulation combines rust inhibitors, biocides and other functional additives to help maintain working-fluid stability while protecting machined components and equipment against corrosion.

Unlike conventional cutting fluid concentrates based on mineral oil, RLT-FS700 is designed as a water-based synthetic additive package. The resulting working solution offers a clean operating environment, low foam characteristics and good resistance to tramp oil, making it suitable for modern CNC machining operations and centralized coolant systems.

The formulation is free of chlorine, phenol and sodium nitrite, making it a practical option for manufacturers looking for an environmentally considerate synthetic coolant formulation.

For production use, the additive package is diluted with water according to actual machining requirements. The recommended dosage is 50%, although the working concentration can be adjusted based on machining conditions and process requirements.

Key Benefits

Strong Rust Protection

RLT-FS700 contains effective rust-inhibiting components to help protect metal parts and machine-tool surfaces during machining operations. This is particularly important when processing alloy steel and cast iron, where corrosion control is an important part of coolant management.

Long Working Solution Stability

The working fluid is formulated for good stability, helping extend coolant service life and reduce the frequency of fluid replacement under appropriate operating conditions.

Tramp-Oil Resistance

The formulation provides strong resistance to tramp oil, helping maintain cleaner coolant conditions in machining systems where lubricating oils and hydraulic oils may enter the working fluid.

Low Foam Performance

Low-foam characteristics make RLT-FS700 suitable for high-speed machining and circulating coolant systems where excessive foam can interfere with fluid circulation and production efficiency.

Cleaner Machine Environment

The working solution leaves minimal residue adhesion, helping keep machine tools and surrounding production areas cleaner during continuous operation.

Good Chip Sedimentation

RLT-FS700 provides good sedimentation performance, helping prevent metal chips and machining debris from accumulating on grinding wheels and within the working system. 

Applications

RLT-FS700 is suitable for water-based cutting and machining applications involving:

• Alloy steel machining

• Cast iron machining

• CNC machining

• NC machining

• MC machining centres

• Centralized coolant systems

• Industrial cutting operations

The product is especially suited to manufacturers that need a fully synthetic cutting fluid additive package with corrosion protection, coolant stability and clean operating characteristics.

Why Choose RLT-FS700 for Industrial Machining?

For industrial coolant formulators and metalworking-fluid users, coolant performance is not determined by corrosion protection alone. Foam control, tramp-oil contamination, fluid stability, residue formation and chip management can all affect daily production.

RLT-FS700 brings these requirements together in one synthetic additive package.

Its formulation is designed to provide a balance between rust inhibition, working-solution stability, low foam, tramp-oil resistance and cleanliness. This makes it suitable for customers developing or using water-based synthetic cutting fluids for CNC and centralized coolant applications.

For B2B buyers, the product can also serve as a flexible additive package rather than a finished ready-to-use coolant. The working concentration can be adjusted according to the actual machining environment, water quality and production conditions.

Recommended Preparation

RLT-FS700 should be prepared carefully to maintain working-fluid stability.

Recommended procedure:

1. Add the RLT-FS700 additive package first.

2. Add the required amount of water.

3. Agitate thoroughly until the working solution is uniform.

4. Adjust the concentration according to the actual machining conditions.

The recommends a 50% dosage, with adjustment possible according to production requirements.

Before full-scale production, customers should conduct qualification trials using their actual equipment, water quality, metals and machining conditions.

Typical Physical Properties

Packaging

RLT-FS700 is available in standard industrial packaging for bulk B2B supply:

• 200 L metal drums

• 1000 L IBC tote tanks

• Net weight: 180 kg per drum

• Net weight: 1000 kg per IBC

• Customized packaging is available upon request.

Storage & Handling

Store RLT-FS700 indoors under normal warehouse conditions. Keep containers away from direct sunlight and prevent water from accumulating on the top of drums or containers.

For industrial applications, the product should be evaluated together with the customer's specific water quality, equipment and machining process before commercial production.

RLT-FS700 for Coolant Formulators and Industrial Buyers

RLT-FS700 can be considered by:

• Metalworking fluid manufacturers

• Cutting fluid formulators

• Metalworking chemical distributors

For companies looking to develop or optimize a water-based fully synthetic cutting fluid, the additive package provides a practical formulation base combining corrosion protection, fluid stability and operating cleanliness.
