Fully Synthetic MWF Additive Package FS800

RLT-FS800 is a fully synthetic metalworking fluid additive package developed for the formulation of water-based machining coolants. It combines selected rust inhibitors, biocides and functional additives to help formulators produce stable, long-life working fluids for industrial metalworking applications.

The additive package is designed to provide reliable rust protection while maintaining working-fluid stability during extended machining operations. It also offers good tramp-oil resistance, low foaming tendency, low deposit formation and effective metal-chip sedimentation, helping keep machine tools and coolant systems cleaner during continuous production.

RLT-FS800 is primarily recommended for machining alloy steel and cast iron, including cutting, grinding, drilling, reaming and tapping operations. It can be used in CNC and machining-center applications as well as centralized coolant systems.

Designed for Industrial Coolant Formulation

For metalworking fluid manufacturers, the stability of the finished coolant is just as important as its initial machining performance. RLT-FS800 is formulated as an additive package to help develop fully synthetic water-based MetalWorking Fluids with a balanced combination of corrosion protection, cleanliness and operating stability.

Its rust-inhibiting system helps protect machined components and metal equipment during processing, while the formulation's resistance to tramp oil can help maintain coolant performance when incidental oil contamination occurs.

The low-foam characteristics are particularly useful in coolant circulation systems where excessive foam can interfere with fluid delivery, filtration or machine operation. Its low tendency to form sticky deposits also supports cleaner machine-tool conditions over extended production periods.

Typical Machining Applications

RLT-FS800 is suitable for formulating coolants for a range of metalworking processes, including:

• CNC machining

• Cutting

• Grinding

• Drilling

• Reaming

• Tapping

• General machining of alloy steel

• Cast iron machining

• Centralized coolant systems

It is especially suitable for industrial machining environments where coolant stability, rust protection and clean operation are important.

Suitable for CNC and Centralized Coolant Systems

RLT-FS800 can be considered for individual machine coolant systems as well as centralized metalworking fluid systems.

For CNC machining centers and other automated equipment, stable coolant performance helps support consistent production conditions. In centralized systems, resistance to tramp oil, low foam and good working-solution stability can be valuable for maintaining coolant quality across multiple machines.

The actual performance of the formulated coolant depends on the complete formulation, dilution water, machining conditions and operating environment. Pre-production testing is recommended before commercial use.

Recommended Dosage

The recommended dosage of RLT-FS800 is 45–50% when preparing the working formulation. The dosage may be adjusted according to the specific machining process, equipment, water quality and production requirements.

For preparation, add RLT-FS800 first, followed by water, and agitate thoroughly to obtain a stable working fluid.

Customers should conduct formulation and application trials before full-scale production.

Typical Physical Properties

Why Choose RLT-FS800?

Balanced Rust Protection

The selected rust inhibitors in RLT-FS800 help provide effective protection against corrosion during machining operations, making the additive package suitable for alloy steel and cast iron applications.

Stable Working Fluid

A stable coolant is essential for long-running machining operations. RLT-FS800 is formulated to support extended working-fluid stability and help maintain consistent coolant performance.

Tramp-Oil Resistance

Unwanted oil contamination is a common challenge in machining environments. RLT-FS800 provides strong tramp-oil resistance to help the formulated coolant remain more manageable during operation.

Low Foam and Cleaner Machines

Low foaming characteristics help make the product suitable for circulating coolant systems, while its low tendency to produce sticky deposits supports cleaner machine-tool surfaces and operating environments.

Effective Chip Sedimentation

RLT-FS800 provides good sedimentation performance, helping metal chips and swarf settle rather than continuously accumulating around grinding wheels and other machining areas.

For Metalworking Fluid Manufacturers

RLT-FS800 is intended for professional metalworking fluid formulation rather than direct consumer use. It can be considered by:

Metalworking fluid manufacturers

• Cutting fluid formulators

• CNC coolant manufacturers

• Industrial lubricant companies

• Metalworking chemical distributors

• CNC machining solution suppliers

• grinding coolant formulators

• Centralized coolant system operators

For OEM and industrial buyers, the formulation can be evaluated according to the required machining process, metal substrate, water quality, coolant concentration and equipment configuration.

Packaging

Standard packaging includes:

• 200 L metal drums — net weight 180 kg

• 1000 L IBC tote tanks — net weight 1000 kg

• Customized packaging can be discussed according to customer requirements.

Storage and Handling

Store RLT-FS800 indoors under normal warehouse conditions. Keep the product away from direct sunlight and prevent water from accumulating on the tops of drums or containers.

For best results, handle and formulate the product according to the applicable technical and safety requirements.
