2k Diamond Varnish

Diamond Finish for Bodies and Models That Want to Last

The Scaleauto 2K Diamond Varnish (SC-9504B) is a two-component varnish specifically formulated for use on plastic, fibreglass, and resin. In a practical 60 ml format, it provides an extra hard protective layer that seals the paint, adds depth to the colour, and leaves a glossy surface that is resistant to wear and the passage of time.

Applications

This varnish is designed for those seeking a quality finishing touch in their modelling projects. Its most common uses include:

• Slot car bodies made of plastic or resin after the painting and decaling process.
• Static models where the paintwork needs to be preserved and delicate surfaces protected.
• Diorama figures and pieces made of resin that require sealing and a uniform finish.
• Any fibreglass piece that requires a high-gloss protective layer.

Compatibility

Formulated to adhere properly to plastic, fibreglass, and resin. It is particularly suitable for slot car bodies worked with water-based or solvent-based paints, provided these are fully cured before application. Refer to Scaleauto's instructions for mixing and drying times of the catalyst.

Finishes

The name "Diamond" refers to the hardness and gloss of the finish once cured: a sharp surface with depth that is highly resistant to abrasion. Ideal for club racing or for collectors who demand the same level of presentation as in a professional preparation workshop.

Application Tips

• As a 2K (two-component) varnish, it requires mixing with its corresponding catalyst before application. Always respect the proportions indicated by Scaleauto.
• Apply in thin, even layers. Two light coats are always better than one thick layer that may cause runs.
• Work in a ventilated area and with appropriate protective equipment (mask and gloves), as 2K products contain isocyanates.
• The working life of the mixture once prepared is limited; plan your session well to make the most of the product.
• For best results, apply with an airbrush at moderate pressure.

Frequently Asked Questions

What differentiates a 2K varnish from a conventional one?

A 2K varnish (two-component) is mixed with a catalyst just before use. The result is a much harder and more resistant film than that of a one-component varnish, with greater resistance to scratches, fuels, and moisture. It is the preferred option for competition finishes and demanding collectors.

Can I apply it with a brush?

Airbrush application is recommended for achieving even, mark-free layers. Brush application is technically possible in small areas, but the result is rarely as homogeneous as with airbrushing.

What paints can I apply it over?

It is compatible with water-based and solvent-based paints on plastic, fibreglass, and resin, provided they are fully cured. If you have used paints from brands like Vallejo, Tamiya, or Kaleido, ensure that the base is well dried before varnishing.

How much coverage does a 60 ml bottle provide?

It depends on the number of layers and the treated surface, but 60 ml is sufficient to varnish several slot car bodies or small scale models. Remember that, being 2K, once mixed with the catalyst, the usage time is limited.

Is it suitable for 3D printed resin parts?

Yes, as long as the piece is properly sanded, primed, and painted. The 2K Diamond Varnish acts as a final sealing layer, not as a substitute for priming.
