Troton Master C48 VHS 2:1 Ultra Speed Air Dry Fast Drying 2K Clear Coat

What is Troton Master C48 VHS 2:1 Ultra Speed Air Dry?

Troton Master C48 VHS 2:1 Ultra Speed Air Dry is an extremely fast-drying two-component acrylic clear coat developed for fast, high-quality automotive refinishing. Thanks to Air Dry technology, the clear coat cures at room temperature without oven drying and is ready for polishing in approximately 60 minutes at 20 °C.

The clear coat has a very high solids content (VHS, Very High Solids), providing an impressive high-gloss finish and excellent colour depth.

C48 VHS is particularly suitable for repair painting where a faster turnaround time is desired without compromising on quality. The short drying time reduces energy consumption and allows painted parts to be finished more quickly.

The clear coat flows smoothly and creates an even, high-gloss finish that generally requires no additional polishing when applied correctly.

Note: Hardener is sold separately.

How to apply Troton C48 VHS 2:1 Clear Coat

• Prepare the surface. Make sure the basecoat is ready for clear coating according to the manufacturer's instructions. Existing paintwork must be thoroughly cleaned, matted and degreased before application.
• Mix the clear coat. Mix 2 parts clear coat with 1 part C48 VHS hardener. No additional thinner is required.
• Adjust the spray gun.
• RP spray gun: 1.2–1.4 mm nozzle, 2.0–2.2 bar
• HVLP spray gun: 1.3–1.4 mm nozzle, 2.0 bar
• Apply the clear coat. Choose the desired number of coats:
• 1.5 coats: First apply a medium, slightly thinner coat, followed by one full coat. Dry film thickness approximately 50–60 µm.
• 2 coats: Apply two full coats. Dry film thickness approximately 60–70 µm.
• Allow flash-off between coats. The flash-off time between coats is approximately 2–5 minutes at 20 °C.
• Allow to dry. The clear coat is ready for polishing in approximately 60 minutes at 20 °C. Drying can be accelerated by heating, reducing the time to approximately 10 minutes at 40 °C.
• Finish the surface if necessary. C48 VHS generally produces a very high-gloss finish without additional polishing. Any dust particles or minor surface imperfections can be removed using suitable sanding and polishing products once the clear coat has cured.
• Note! Do not exceed the recommended amount of hardener. Drying time increases significantly at temperatures below 20 °C. The manufacturer does not recommend IR drying.

Wear appropriate personal protective equipment suitable for 2K painting and ensure adequate ventilation.

Does the clear coat need polishing after application?

Generally, no. When applied correctly, C48 VHS provides an extremely glossy and even finish. If dust particles remain on the surface, they can be removed after the clear coat has dried, followed by polishing if necessary.

Can the clear coat be applied over existing paintwork?

Can the clear coat be dried without a spray booth oven?

Yes! Thanks to Air Dry technology, the clear coat cures at room temperature. This saves time and energy and allows fast application without separate oven drying.

How many coats of clear coat should be applied?

The manufacturer recommends 1.5–2 coats. The final number of coats depends on the spraying technique and the desired dry film thickness.
