Semi-Finished Compound Lubricant FS101

RLT-FS101 Semi-Finished Compound Lubricant | Low-Oil Semi-Synthetic Additive Package

Most metal fluid manufacturers and machining workshops source separate lubricants, rust preventatives and anti-tarnish chemicals to mix their own coolants. This method takes up extra storage space and raises material management costs. Our RLT-FS101 solves this issue as a complete additive package, formulated as a ready-to-blend semi-finished compound lubricant for water-based grinding and cutting fluid production.

This low-oil concentrated additive package only requires regular tap water for on-site dilution, no extra auxiliary chemicals needed. The finished working fluid balances heat dissipation, lubrication and chip cleaning well. Shop operators often mention its quick foam breakdown performance—no sudden machine downtime caused by foam overflow on high-pressure grinding equipment.

We excluded all restricted hazardous materials during formula development: no sodium nitrite, phenols or heavy metals. This simplifies waste liquid processing work, and export manufacturers will not face environmental certification barriers when shipping metal finished parts. The additive package works for mixed production lines processing cast iron, carbon steel, alloy steel, aluminum and copper, so you do not need to stock multiple coolant raw materials for different workpiece metals.

Core Practical Advantages for Machining Workshops Most generic bulk additive packages only cover basic lubrication needs. After years of field cooperation with auto component, mold and aluminum profile factories, we tuned RLT-FS101 to fix daily production troubles that cheap standard formulas cannot handle.

This additive package delivers consistent anti-corrosion protection across all mainstream industrial metals. Lab testing held 45# carbon steel, red copper and LY12 aluminum alloy at 55°C for 8 hours, all meeting Grade A anti-tarnish standards. One single semi-finished compound lubricant additive package fits all ferrous and non-ferrous machining lines, cutting down your material SKUs and capital locked up in inventory.

It maintains stable performance even when mixed with hard well water. Factories in inland high-hardness water areas frequently encounter coolant stratification and sediment when using ordinary additives; our optimized surfactant system avoids flocculation or liquid separation, extending the service life of circulating tank fluid significantly.

Foam control is a practical upgrade for continuous mass production. At 5% dilution ratio, foam height stays below 2mL after 10 minutes static testing. Grinding facilities running large-flow coolant pumps rarely report filter blockages or inaccurate dimensional measurements triggered by excess foam.

Environmental compliance helps factories cut long-term operating costs. Undetectable nitrite levels remove the need for expensive sewage treatment additives. Waste liquid can go through standard simple separation equipment without complicated pre-treatment steps.

A stable lubricating film from this additive package reduces tool abrasion noticeably. Operators see longer tool service life and smoother workpiece surface finish, lowering rework rates for secondary polishing. Diluted fluid remains clear and odor-free for weeks with routine daily tank maintenance.

On-Site Dilution & Concentration Guidance 

Mixing steps are easy for regular workshop staff, no professional chemical training required. Always add water first to prevent unstable liquid state of the additive package.

1. Fill your cooling tank with clean room-temperature water first, then slowly pour in RLT-FS101 semi-finished compound lubricant additive package while stirring continuously.

2. Keep stirring until the whole liquid becomes fully transparent with no suspended particles before you start machining equipment.

3. Standard mixing ratio: this additive package accounts for 45–55 wt.% of total finished working fluid.

Field adjustment tip: For heavy-load grinding on hard alloy steel, raise concentration to 55% for stronger lubrication. For light aluminum cutting tasks, stick to 45% to control raw material consumption costs.

Common Customer Questions  

Q: Can this semi-finished compound lubricant additive package run mixed aluminum and cast iron production lines? 

A: Yes, we added dual anti-corrosion ingredients for ferrous and non-ferrous metals in the additive package formula. It passes 8-hour high-temperature corrosion testing for aluminum alloy, copper and carbon steel, so you do not need separate coolants for different metal batches. This simplifies daily workshop management greatly.

Q: Will high-pressure grinding machines generate thick foam with this additive package? 

A: Foam overflow will not appear under normal production loads. Lab test data shows foam height below 2mL after 10 minutes rest at 5% dilution. We have collected stable long-term feedback from dozens of grinding factories running large-flow coolant pumps.

Q: Does this additive package meet global environmental rules for export factories? 

A: It fully complies with domestic waste discharge standards and EU environmental access requirements. The additive package formula contains no sodium nitrite, phenols or heavy metals, and nitrite cannot be detected via professional test strips. We can supply all compliance documents on request.

Q: Does hard well water break down diluted coolant mixed with this additive package? 

A: We optimized this additive package specifically for regions with high-hardness tap water and well water. Liquid separation, sediment and flocculation will not form after mixing, and circulating coolant maintains steady performance for long-term use.

Q: How long can diluted working fluid mixed with this additive package stay usable before replacement? 

A: With daily simple tank cleaning and maintenance, the transparent diluted liquid will not turn turbid or develop strange odors for weeks. Its usable cycle is far longer than low-cost generic additive packages sold widely on the market.
