Novol N99234 Ultra Klarlack 400 – Acrylic Clearcoat, 1.0 Litre (2:1)
The Novol N99234 Ultra Klarlack 400 is a high-quality, two-component (2K) acrylic clearcoat from the "Ultra" line, designed for technicians who need a reliable, high-gloss finish with excellent application properties. This 1.0-litre unit is a "Medium Solids" (MS) clearcoat, making it slightly thinner and easier to spray than heavier HS coatings - perfect for achieving a smooth, factory-style finish on spot repairs or full panels without excessive "orange peel."
It is widely regarded as a "user-friendly" clearcoat that offers great "vertical stability," meaning it is highly resistant to runs and sags even when applied in thicker layers.
Key Features & Benefits
- High Gloss & Transparency: Delivers a deep, glass-like shine that enhances the metallic flake and color depth of the underlying basecoat.
- Excellent Leveling: The MS formula flows out beautifully across the panel, resulting in a smooth surface that requires minimal flatting and polishing.
- Easy Application: Forgiving for painters of all skill levels; it has a wide application window and is less sensitive to "dry spray" than some high-solids alternatives.
- UV Protection: Fortified with light stabilizers to prevent the clearcoat from yellowing or cracking under long-term sun exposure.
- Fast Drying: Optimized for a quick "dust-free" time, which is essential for shops without a high-end downdraft spray booth.
- Chemical Resistance: Once fully cured, it provides a tough barrier against road salt, bird droppings, and fuel spills.
Professional Application Guidelines
- The 2:1 Mix: To ensure the clearcoat cures to its intended hardness, you must mix this 1.0L tin with 500ml of Novol Ultra Hardener 400.
- Application: Apply 2 full coats. Allow a 5–10 minute flash-off between coats. The surface should be "matte" or slightly tacky before the second coat is applied.
- Thinning: While usually ready-to-spray once mixed with hardener, you can add up to 10% Novol N65511 Thinner if you are spraying in high temperatures (above 22°C) to keep the "wet edge" open longer.
- Curing Times:
- At 20°C: Dust-free in 20–30 mins; ready to handle in 6–8 hours.
- At 60°C (Bake): Ready to polish after 30 mins of baking plus cooling time.
Why Choose Ultra Klarlack 400?
If you find that "High Solids" clears are sometimes too thick or difficult to get flat, the Ultra 400 is your solution. It provides the same professional-grade protection but with a much easier "flow," making it the ideal choice for DIY restorers and busy body shops alike who want a high-quality finish without the struggle.
