Silicone 8000CPS

Silicone 8000CPS: controlled grip for slot tyres

Silicone for tyres is one of the most important consumables in preparing a slot car, and viscosity changes everything. The Silicone 8000CPS (MP010-8000) is positioned in the high viscosity range, resulting in a denser layer on the tyre, longer product contact time, and more persistent and progressive grip on track.

What does the 8000CPS viscosity provide?

Viscosity is measured in centipoise (CPS) and determines the behaviour of the product once applied to the tyre. Higher CPS means the silicone is thicker and penetrates the rubber more slowly, generating a lasting and stable grip effect. The 8000CPS is a common choice among preparers and club racers looking for:

• Increased adhesion on technical tracks with many tight corners.
• A more consistent grip throughout the session, without peaks or sudden drops.
• Better performance with hard or semi-hard rubber tyres.
• Less need to reapply between heats.

Application and use

The application technique directly influences the result. With a silicone of this viscosity, it is common to apply a moderate amount to the tyre and allow it to penetrate before running. It is not necessary to soak: a uniform layer is sufficient to activate the grip. Some preparers combine it with lower viscosity silicones to adjust the grip point to track conditions.

It is compatible with standard rubber tyres used in slot racing. It is not recommended for use on urethane or foam tyres, as the behaviour may differ from what is expected.

Ideal for…

• Club racers competing in championships with open preparation regulations.
• Enthusiasts preparing their cars for technical tracks or surfaces with lower adhesion.
• Preparers working with rubber tyres in Sidewinder, Inline, or Anglewinder configurations.

Aspects to consider

A high viscosity like 8000CPS can be excessive on tracks with a lot of natural grip or very adhesive surfaces, where it may cause over-grip that hinders driving. In such cases, combining it with a lower CPS silicone or reducing the amount applied is the best solution. Experience and knowledge of the track are always the best fine-tuners.

Frequently asked questions

What is the difference between an 8000CPS silicone and one of lower viscosity?

The higher viscosity makes the silicone denser and absorbed more slowly into the tyre. This generates a more durable and stable grip, although it may be excessive on already adhesive tracks. Lower CPS silicones are more fluid and provide more immediate grip but less persistence.

How often should the silicone be reapplied?

It depends on the duration of the session, the type of tyre, and the track conditions. Generally, with a high viscosity like 8000CPS, the effect lasts longer than with lighter silicones. It is common to reapply between long heats or when a drop in grip is noticed.

Is it compatible with all tyres?

It is designed for rubber tyres. On urethane or foam tyres, the behaviour may vary and may not always produce the desired effect, so we do not recommend it for those materials.

How is it applied correctly?

The most common method is to place a small amount on the tyre mounted on the car and spread it evenly, allowing it to penetrate before running. It is not necessary to apply excessively: a thin and homogeneous layer is sufficient. Running a few laps at a moderate pace at the start helps to settle the product.

Can it be mixed with other silicones?

Yes. Many preparers mix silicones of different viscosities to adjust the grip level to the characteristics of each track. Combining the 8000CPS with a lower CPS silicone allows for finding a middle ground adapted to each surface and condition.

The Silicone 8000CPS (MP010-8000) is a high-viscosity silicone tyre treatment for slot cars, delivering long-lasting grip and consistent performance lap after lap. Designed for rubber tyres in Sidewinder, Inline and Anglewinder setups, it is a go-to choice for club racers and serious hobbyists seeking reliable traction on technical tracks.
