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 dries at room temperature without oven drying and is ready for polishing in approximately one hour at 20 °C.
The clear coat's very high solids content (VHS, Very High Solids) provides a durable, high-gloss finish with excellent colour depth. The clear coat flows smoothly and creates an impressive finish that generally requires no additional polishing when applied correctly.
Fast drying reduces the time required for painting and lowers energy consumption, as separate oven drying is not necessary. This makes C48 VHS Clear Coat an excellent choice for both professional body shops and experienced DIY painters.
The kit includes clear coat and hardener. The clear coat is mixed with the hardener at a ratio of 2:1, and no additional thinner is required.

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 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 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. IR drying is not recommended.
Wear appropriate personal protective equipment suitable for 2K painting, particularly adequate respiratory protection, and ensure sufficient ventilation.
