Overview
What is 2K Acrylic HS Clear Coat?
ZN-330 2K Acrylic HS Clear Coat is a premium high-solids (HS) clear coat developed for workshops aiming for the highest standard of repair quality. Thanks to its high solids content, it builds a full film even with a 1.5-coat application, giving the surface glass-like depth and a mirror-like gloss. It is the clear coat of choice for top-quality repairs where a result as close as possible to the original factory finish is expected.
The densely cross-linked film structure offers superior resistance to fine scratches caused by car wash brushes and everyday use. Very high UV stability and strong resistance to yellowing keep the gloss and colour purity intact for a long time, especially on white and light colours. Its resistance to fuel, bird droppings and washing chemicals provides lasting surface quality that preserves the appearance of the vehicle.
ZN-330 is mixed 2 : 1 by volume with ZN-440 2K HS Hardener and, when necessary, thinned with 0–5% ZN-510 Acrylic Thinner. In a premium repair system, it is applied as the topcoat over a surface prepared with ZN-220 5+1 HS Acrylic Primer and then coated with basecoat. On spot repairs, the blend edge can be made invisible with ZN-520 Blending (Fade-out) Thinner; ZN-530 Surface Cleaning Thinner is recommended for pre-paint surface cleaning.

Application
Step-by-step application
The recommended application sequence for a professional result.
- 01
Surface preparation
Wait for the basecoat to complete its flash-off (until it turns matt) and wipe the surface lightly with a tack cloth. An ambient and part temperature of approximately 20 °C is ideal for the clear coat to flow out.
- 02
Mixing
Mix 2 parts by volume of ZN-330 with 1 part of ZN-440 hardener. If necessary, add 0–5% ZN-510 to adjust the viscosity to 18–20 s in a DIN 4 flow cup, then strain the mixture into the spray gun.
- 03
First coat
Using an HVLP gun fitted with a 1.3–1.4 mm nozzle at approximately 2.0 bar inlet pressure, apply a thin but closed first coat. This coat helps the second coat to grip the surface and flow out without running.
- 04
Full coat
Once the first coat has tacked up slightly, apply the full wet second coat within approximately 3–5 min. Aim for a total dry film thickness of 50–70 µm; avoid excessive film build.
- 05
Drying
Allow a 5–10 min flash-off before baking. Dry the part for 30–40 min at 60 °C object temperature or leave it for at least 16 h at 20 °C.
- 06
Polishing
If necessary, once the part has cooled completely, remove dust nibs by fine sanding and polishing. As surface hardness increases over time, carrying out corrections within the first day after drying makes the job easier.
Storage and safety
- Store in the original container with the lid tightly closed, at 5–25 °C in a cool, dry place; protect from direct sunlight and heat sources.
- Flammable liquid: keep away from naked flames and sources of sparks; apply only in a ventilated spray booth.
- Use mixed product within its pot life; do not store leftover mixture in a closed container or pour it back into the original container.
- The mixture contains isocyanates and may cause an allergic reaction. Wear suitable personal protective equipment and read the product's Safety Data Sheet (SDS) for full details.
