KF-968-100CS

Shin-Etsu Japan KF-96 100CS is a low-viscosity dimethyl silicone oil. Leveraging its excellent thermal stability, chemical inertness, and low surface tension, it is widely used in the following fields:

I. Industrial Manufacturing and Mechanical Maintenance

1. Lubrication of Precision Machinery

The viscosity characteristics of 100CS make it particularly suitable for high-speed rotating bearings, gearboxes, and precision instruments (e.g., optical lens drive mechanisms). It can reduce the coefficient of friction (approximately 0.08 on metal surfaces) and minimize wear. For instance, in the wafer transfer systems of semiconductor equipment, its low volatility prevents contamination of sensitive components.

2. Applications in High-Temperature Environments

It can operate stably within the range of -50℃ to 180℃, making it suitable for lubricating high-temperature chain oils or oven conveyor belts. With a flash point >300℃, it significantly reduces the risk of fire.

3. Release Agent and Anti-Adhesion Treatment

During the injection molding of plastics such as ABS and PP, it forms a nanoscale hydrophobic film, reducing the release force by 40% while extending the mold cleaning frequency (from once a day to once a week).

II. Electronics and Electrical Field

1. Insulating and Heat Dissipating Medium

As insulating oil for small transformers or capacitors, it has a dielectric strength of 50 kV/mm and a volume resistivity of 1×10¹⁴ Ω·cm. It can replace mineral oil and improve low-temperature fluidity. In LED packaging, when compounded with thermally conductive fillers, it can increase the thermal conductivity to 1.2 W/m·K, effectively reducing the chip junction temperature.

2. Protection of Electronic Components

When sprayed on the surface of printed circuit boards (PCBs), it forms a moisture-proof and anti-corrosion coating, which is especially suitable for outdoor equipment in humid environments (e.g., smart electricity meters).

3. Treatment of Optical Components

When a 0.1μm-thick film is coated on camera lenses or endoscope lenses, the haze can be reduced from 2.5% to 0.8%, while improving anti-fingerprint performance.

III. Food and Cosmetics Industry

1. Food-Contact-Grade Applications

It complies with the FDA 21 CFR 173.340 standard, with a residue content < 0.1 ppm. It can be used for the release of baking molds, anti-adhesion of candies, and lubrication of food processing equipment (e.g., chains in chocolate production lines).

2. Basic Raw Material for Cosmetics

As an emollient in skincare products, it forms a breathable protective film to prevent skin moisture loss and imparts a silky texture to the products. When added to hair conditioners, it improves the combability of damaged hair after dyeing.

IV. Solutions for Special Scenarios

1. Environmentally Friendly Defoamer

When added at 0.05-0.2% in water-based coatings or sewage treatment, it can eliminate over 95% of foam without affecting subsequent processes (e.g., coating curing).

2. Aerospace and Precision Instruments

With a viscosity change rate < ±10% (from -50℃ to 180℃), it is used as damping oil for aircraft attitude sensors or precision lubrication for missile guidance systems.

3. Textile Treatment

As a fiber lubricant, it can reduce the friction coefficient of sewing threads and lower the thread breakage rate, making it especially suitable for the processing of high-strength synthetic fibers (e.g., aramid fibers).

V. Chemical and Coating Field

1. Coating Additive

Adding 0.1-1% of it can improve the leveling property of coatings, prevent cratering and orange peel effects, and at the same time enhance the adhesion of coatings to plastic substrates.

2. Carrier for Chemical Reagents

As a reaction medium or catalyst carrier, its chemical inertness prevents interference with sensitive reactions (e.g., noble metal-catalyzed hydrogenation).

VI. Performance Advantages and Selection Recommendations

Differences from KF-96 350CS: 100CS has stronger fluidity and is suitable for scenarios requiring rapid penetration (e.g., lubrication of micro-hole bearings), while 350CS focuses more on high-load wear resistance.

Safety and Certification: It is registered under REACH and contains no SVHC substances, making it safe for use in medical equipment (e.g., lubrication of surgical instruments).

Dilution and Compatibility: It can be mixed with toluene or xylene at a 1:1 ratio for precision cleaning, or compounded with emulsifiers to form water-based release agents.

In summary, relying on its precise viscosity control and multi-scenario adaptability, KF-96 100CS has become the preferred alternative to traditional mineral oils, and is irreplaceable especially in the fields of high-speed operation, wide temperature range, and precision manufacturing.
