2k Diamond Varnish Pack

Professional 2K Varnish for Your Slot and Modelling Projects

The Scaleauto 2K Diamond Varnish Pack (SC-9504A) brings together all the necessary components in one kit to apply a high-resistance two-component varnish on plastic, fiberglass, and resin. A complete system designed for those seeking a durable, deep finish with a diamond-like shine that is difficult to achieve with conventional single-component varnishes.

Pack Contents

The kit includes three elements that work together:

• 60 ml of 2K Diamond Varnish: the base of the system, formulated to adhere firmly to plastic, fiber, and resin.
• 60 ml of Thinner: allows you to adjust the viscosity of the varnish to suit the application method, whether using an airbrush or brush.
• 30 ml of Hardener: the catalyst that activates the two-component chemical reaction, ensuring proper curing and final hardness of the finish.

Why Choose a 2K Varnish?

Two-component (2K) varnishes are distinguished from single-component ones by their chemical curing process: mixing the varnish with the hardener triggers a reaction that generates a much harder film, resistant to impacts, solvents, and abrasion. This makes them the preferred option for preparing competition slot car bodies, 3D printed resin parts, and static models where the finish needs to withstand continuous handling.

Applications and Compatibility

The 2K Diamond Varnish Pack is suitable for:

• Slot car bodies made from injected plastic or resin after the painting and decoration process.
• Fiberglass parts such as chassis or handmade fairings.
• Parts printed in photopolymer resin (SLA/MSLA) in the field of modelling, figures, and dioramas.
• Any static model project that requires a high-gloss final seal and protection.

Mixing and Application Tips

To achieve the best results, consider these points before applying:

1. Always respect the mixing ratio indicated by Scaleauto between varnish and hardener. Once mixed, the pot life (working time) is limited: prepare only the amount you will use in the session.
2. Adjust the viscosity with the included thinner according to the application method. For airbrush, a more fluid mixture facilitates atomization and avoids orange peel.
3. Apply in thin layers and allow the appropriate flash-off time between layers.
4. Work in a well-ventilated environment and use respiratory protection, as 2K components are sensitising.
5. Once cured, the varnish can be polished with fine abrasive paste to further enhance the final shine.

Frequently Asked Questions

Can I apply the 2K Diamond Varnish with an airbrush?

Yes. By using the included thinner to reduce viscosity, the varnish atomises well in an airbrush. Adjust the pressure and distance according to your preferences and the type of needle/nozzle you use.

How long do I have to work with the mixture once the hardener is added?

The working time (pot life) of 2K varnishes is limited and varies with ambient temperature. Higher temperatures accelerate curing. Prepare only the amount you will use in the working session to avoid waste.

Is it necessary to sand or prime the piece before applying the varnish?

The varnish acts as a finishing and protective layer, not as a primer. The piece must be clean, dry, and with the painting or decoration already completed before varnishing.

Can it be used over decals?

Yes, in fact, varnishing over decals is a common practice in slot and modelling to seal, protect, and visually integrate them with the rest of the bodywork.

Is the 2K Diamond Varnish suitable for 3D printed resins?

According to the product information, it is suitable for resin, making it compatible with SLA/MSLA printed parts once they have been properly cured, washed, and sanded.

The Scaleauto SC-9504A 2K Diamond Varnish Pack is a professional two-component varnish kit designed for slot car bodies, resin parts, and fiberglass components. Including 60 ml of 2K diamond varnish, 60 ml of thinner, and 30 ml of hardener, it delivers a durable, high-gloss protective finish ideal for slot racing preparation, static scale models, and resin miniatures. A must-have for hobbyists seeking a factory-level topcoat on their builds.
