Silicone 3500CPS

The right viscosity for demanding maintenance

When we talk about preparation in slot or precision modelling, detail makes the difference. The Silicone 3500CPS (reference MP010-3500) is a maintenance product with a medium-high viscosity of 3500 centipoise, placing it at an ideal point between fluidity and consistency: it flows enough to penetrate and cover well, but does not drip or get lost where it shouldn't.

Main features

• Viscosity 3500 CPS: higher density than fine low-viscosity silicones, resulting in a more persistent layer on the treated surface.
• Pure silicone formulation: free from aggressive solvents that could deteriorate rubber, plastics or resin parts.
• Controlled application: the medium-high consistency allows for precise dosing, avoiding excesses that could contaminate sensitive areas such as the track or braids.
• Reference MP010-3500: clear identification for replenishment without confusion.

Recommended applications

The 3500 CPS silicone is particularly useful in the following contexts:

• Slot tyre treatment: applied to the tread, it improves progressive grip and extends the lifespan of the rubber.
• Lubrication of sliding parts: axles, bushings, mounts and any component requiring a non-aggressive and durable lubricant.
• Guide maintenance: facilitates the sliding of the guide in the track, reducing wear.
• Static modelling and dioramas: useful for achieving specific finishes, protecting rubber parts or facilitating the assembly of flexible components.

Behaviour and performance

Unlike very low viscosity silicones (100-500 CPS), which penetrate quickly but evaporate or redistribute easily, the 3500 CPS remains longer in the application area. This makes it ideal when we want a treatment that withstands several running sessions without the need for constant reapplication.

At the same time, its viscosity does not reach the density of silicone pastes or greases, allowing it to be applied with a cloth, a swab or directly from the container without the need for special tools.

Usage recommendations

• Always apply in small amounts and spread evenly: with this type of product, less is more.
• Avoid direct contact with track rails and car braids, as silicone can reduce electrical conductivity.
• For tyres, apply with a soft cloth and let it act for a few minutes before running.
• Store the product in a cool place away from direct light to maintain its properties long-term.

Frequently asked questions

What is the difference between a 500 CPS silicone and this 3500 CPS one?

Viscosity measures the resistance of the fluid to movement: the higher the CPS, the thicker and more persistent the silicone. The 500 CPS is very liquid and penetrates well into fine pores, while the 3500 CPS forms a thicker and more durable layer, ideal for surfaces where more protection or sustained grip is needed.

Can I use it on silicone tyres and also on rubber tyres?

Yes, the silicone is compatible with both types of compound. It does not attack the material and helps maintain the flexibility of the rubber, especially in tyres that are stored for a long time.

Does it affect the electrical conduction of the car?

Silicone is a dielectric material, meaning it does not conduct electricity. Therefore, it is important not to apply it to the braids or track rails, as it could cause loss of electrical contact and affect the car's performance.

How often should the treatment be reapplied on tyres?

It depends on the running pace and the type of track. Generally, with a viscosity of 3500 CPS, the effect lasts several sessions. Observe the behaviour of the tyre: when you notice that grip decreases or the rubber loses flexibility, it is time to re-treat.

Is it suitable for plastic and resin parts in models or dioramas?

Yes, pure silicone does not attack ABS plastic, polystyrene or common epoxy resin used in modelling. It can be used to protect parts, facilitate demoulding or provide a slightly satin finish on rubber or vinyl elements.

The MP010-3500 silicone fluid at 3500 CPS viscosity is an essential maintenance product for slot car enthusiasts and scale modelling hobbyists. Its medium-high viscosity makes it ideal for tyre treatment, axle lubrication, guide rail maintenance and the care of flexible plastic or rubber components. Compatible with silicone and rubber tyres across all slot scales, including 1:32 and 1:24, this product helps extend the lifespan of key components while improving performance on track. A reliable choice for club racers, home layout builders and static modellers alike.
