Silicone 800CPS

800CPS Silicone: measured and consistent grip for your slot tyres

The 800CPS Silicone (ref. MP010-800) is a liquid tyre treatment specifically designed for the slot car world. Its viscosity of 800 centipoise (CPS) places it in the medium-high range of hobby silicones, resulting in a more controlled application and a lasting grip effect without excessively soaking the tyre.

Main features

• 800CPS viscosity: denser than entry-level silicones (100-200CPS), it penetrates less and stays on the tyre surface longer.
• Durable grip effect: the treatment remains active for a greater number of laps, reducing the frequency of reapplication.
• Clean application: the viscosity prevents drips and makes it easy to dose the right amount with a fine brush or tip applicator.
• Compatible with rubber and polyurethane tyres commonly used in competitive and recreational slot racing.

What does 800CPS viscosity offer compared to other silicones?

In the market for slot tyre treatments, silicones of very different viscosities coexist. The more fluid ones (100-200CPS) penetrate the tyre quickly and provide a very pronounced initial grip peak, but they wear out faster. The 800CPS ones act more superficially and progressively: the tyre becomes more adherent without excessive deformation, which is particularly useful in long sessions or when competing in clubs where soaking the tyre in each run is not allowed.

Recommended applications

• Preparation of tyres before club sessions or championships.
• Maintenance of already used tyres that have lost their optimal grip level.
• Use on tracks with smooth or highly polished surfaces, where more bite is needed without resorting to very aggressive silicones.
• Pre-treatment before tyre turning to improve grip uniformity.

Usage tips

1. Clean the tyre with a dry cloth or distilled water before applying the silicone.
2. Apply a small amount with a fine brush to the tread. With 800CPS, less is more: a thin layer is sufficient.
3. Allow to act for a few minutes before mounting the wheels and running the first warm-up laps.
4. If the tyre becomes too sticky, reduce the amount in the next application.
5. Store the product capped and away from heat sources to preserve its original viscosity.

Frequently asked questions

What is the difference between 800CPS silicone and 200CPS silicone?

The main difference is viscosity: the higher the CPS number, the denser the silicone. The 200CPS is more liquid, penetrates the tyre faster, and offers a very quick but more ephemeral grip peak. The 800CPS acts more superficially and durably, ideal for those who prefer stable and predictable grip throughout the session.

Is it compatible with all types of slot tyres?

Generally yes, although the result may vary depending on the tyre compound. It works particularly well with medium hardness silicone and polyurethane rubbers. On very soft tyres, a minimal amount may be sufficient; on harder tyres, a second thin layer may be needed.

How often should I apply it?

It depends on the type of track, the hardness of the tyre, and the demands of the session. As a reference, one application is usually sufficient for a continuous running session of 20-30 minutes. If you notice a loss of grip before that time, you can apply a second thin layer.

Can it negatively affect the track?

If applied correctly and in the right amount, it should not leave significant residue on the track. An excess of silicone, regardless of viscosity, can stain the track and affect other cars. The 800CPS density helps to better control the dosage.

Can it be used for both competition and recreational use?

Yes. It is equally valid for preparing a club car as for fine-tuning the tyres of a home slot track. In competition, it is advisable to check the championship regulations, as some do not allow grip treatments during the race.

The 800CPS Silicone (ref. MP010-800) is a medium-high viscosity tyre treatment designed for slot car racing. Whether you race on Scalextric, Carrera, Scaleauto or Ninco tracks, this silicone provides consistent grip over extended sessions without over-saturating the tyre compound. Ideal for club racing, home track use, and tyre preparation before competition. Available at Ministry of Hobby, your specialist slot car and scale modelling store.
