Silicone 2500CPS

Silicone 2500CPS: controlled lubrication for slot workshop and modelling

When preparing a car for the track, every detail counts. Lubrication is one of the aspects that is often overlooked, yet it has a significant impact on the performance and durability of components. The Silicone 2500CPS (ref. MP010-2500) offers a medium-high viscosity that makes it a very suitable option for those points where we need a lubricant that stays in place and works continuously.

Main features

The CPS (centipoise) viscosity is the unit that measures a fluid's resistance to flow. The higher the number, the greater the density of the lubricant. With 2500CPS, this silicone falls into the medium-high range: it is not as light as silicones of 100 or 350CPS —designed for very delicate parts or tyre treatments— nor as dense as those of 10,000CPS or more, intended for cushioning or sealing. Its working range is ideal for:

• Lubrication of front and rear axles.
• Bearing and bushings.
• Articulation points of flexible chassis.
• Steering and guide mechanisms.
• Crown gear and pinion when a lubricant slightly more consistent than a light silicone is sought.

Recommended applications

In the world of slot racing, choosing the right lubricant makes the difference between a car that runs smoothly and one that transmits vibrations or generates unnecessary heat at friction points. The 2500CPS silicone is especially useful when:

• We want the lubricant not to move easily due to centrifugal force or vibration.
• We are working in areas that cannot be cleaned and relubricated in each session.
• We seek long-lasting protection against wear in plastic or metal bearings.

It also has applications in static models and dioramas to create effects of viscous fluids, wet surfaces, or translucent elements with body.

Behaviour and performance

Silicone, unlike conventional mineral or synthetic oils, is compatible with most plastics, rubbers, and elastomers. It does not attack silicone tyres or polyurethane parts, making it safe for use in practically any point of the chassis without the risk of material deterioration.

Its consistency at 2500CPS ensures a stable lubricating film that effectively reduces friction, prolongs the lifespan of moving components, and helps maintain lap consistency during long sessions on the track.

Usage recommendations

• Always apply in small amounts: with silicone, less is more.
• Use a fine applicator or a toothpick to place the drop exactly where needed, avoiding migration to the braids or guide.
• Clean any excess with a cloth or swab before putting the car on the track.
• For ball bearings, apply a drop on the outside of the bearing and let it penetrate before mounting the axle.
• Do not mix with mineral oils or other lubricants at the same application point.

Frequently asked questions

What is the difference between a 2500CPS silicone and a 350CPS one?

The difference lies in the viscosity, that is, how "thick" it is. The 350CPS is much more fluid and is used for very delicate parts or for surface treatments where quick penetration is needed. The 2500CPS is denser, stays better at the application point, and offers a more durable lubricating film in areas of higher load or vibration, such as bearings and axles.

Can I use this silicone on tyres to improve grip?

No. Tyre treatments to improve grip use very low viscosity silicones or specific products formulated for that function. Applying a 2500CPS silicone on tyres would reduce grip instead of increasing it.

Is it compatible with plastic and metal bearings?

Yes. The silicone is compatible with both materials. It does not attack the common technical plastics in slot chassis nor the metals of ball bearings.

How much should I apply at each point?

A very small drop is sufficient in most cases. Excess lubricant does not improve performance and can migrate to areas where it should not be, such as the braids or guide, negatively affecting electrical contact.

Does it have applications in static modelling or dioramas?

Yes. The medium-high viscosity silicone can be used to reproduce effects of dense fluids, oily surfaces, or translucent elements with volume in dioramas and static models.

The MP010-2500 silicone oil at 2500CPS viscosity is a versatile lubricant for slot car preparation, model engineering, and diorama crafting. Compatible with plastics, rubbers, and metals, it provides a stable lubricating film for axles, bearings, gears, and articulation points. An essential workshop fluid for slot car hobbyists, scalextric enthusiasts, and scale modellers seeking reliable, long-lasting lubrication without damaging sensitive components.
