Achieve The Ultimate Mirror Finish Glasurit 923-666 Premium 2K HS Clearcoat

For custom painters and high-end automotive refinishers, the clearcoat is not just a protective layer—it is the defining statement of your craftsmanship. Glasurit 923-666 HS Clearcoat VOC is engineered to deliver an unmatched, deep-gloss "wet look" that makes metallic flakes pop and solid colors look incredibly rich.

Formulated with BASF's legendary polyurethane resin technology, this high-solids clearcoat flows out beautifully to eliminate orange peel, giving your projects a glass-like, premium mirror finish that lasts.

Glasurit 923-666 is formulated with a high-density, crosslinked acrylic polyurethane polymer structure:

This unique molecular design balances extreme surface hardness (to resist scratches and stone chips) with structural flexibility (allowing the film to expand and contract under extreme temperature shifts without cracking).

When compared to other premium clearcoats like PPG DC4000 or Sikkens Autoclear HS Plus, Glasurit 923-666 offers distinct operational advantages:

• Unmatched Depth and Visual Thickness: While some European clearcoats look thin and "OEM-like," Glasurit 923-666 provides a rich, thick, crystal-clear build that is highly favored in premium custom car and motorcycle markets.
• Exceptional Polishing Latitude: Many scratch-resistant clearcoats cure to a glass-hard state that is incredibly difficult to sand and polish. Glasurit 923-666 strikes a perfect balance: it offers high scratch resistance but remains highly receptive to compounding and polishing, making it easy to remove dust nibs without leaving holograms.
• Perfect Compatibility with Waterborne Basecoats: Specifically optimized to lay over waterborne paint systems (such as Glasurit 90 Line). It will not lift, bleed, or cause loss of gloss over water-based pigments.

Glasurit 923-666 is the preferred choice for projects where compromise is not an option:

Protects intricate airbrush art, pinstriping, and multi-layered candy paint on premium bikes (e.g., Harley-Davidson, Ducati). The high-build formula completely buries the edges of decals and graphics for a seamless, smooth-to-the-touch surface.

Provides a durable, non-yellowing protective shield for full-car color changes on supercars, ensuring the custom paint retains its showroom shine under intense sunlight.

Formulated to withstand the harshest environments, making it ideal for protecting exotic wood veneers and carbon fiber accents inside luxury yachts against salt air and UV degradation.

To achieve a flawless finish in any climate, adjust your application technique according to the ambient temperature:

5. Temperature-Specific Adjustments

• Cold Climates (<15°C): Air drying is not recommended. Always use force drying (60°C oven or IR lamps) to ensure complete chemical crosslinking.
• Standard Conditions (15°C - 25°C): Follow the standard 2:1 mixing ratio. Use standard flash-off times (3-5 minutes between coats).
• Hot/Humid Climates (>30°C): Add up to 10% of a slow retarder/thinner (anti-blushing agent) to prevent dry spray and solvent trapping.

2. Standard Application Steps

1. Mix: Blend 2 volumes of 923-666 with 1 volume of 929-666 Hardener. Stir thoroughly for 60 seconds.
2. Apply First Coat: Spray a full wet coat using a 1.3mm or 1.4mm nozzle.
3. Flash-off: Wait 3 to 5 minutes. Test the overspray on masking paper; it should be tacky but not transfer.
4. Apply Second Coat: Spray a second full wet coat.
5. Final Flash: Allow the panels to sit at room temperature for 5 to 10 minutes to let the solvent release safely before baking.
6. Bake: Cure at 60°C for 30 minutes, or air dry at 20°C overnight (10 hours).

Proper storage is critical to maintaining the chemical integrity of premium 2K polyurethane materials:

• Storage Environment: Store in a dry, cool, well-ventilated space at temperatures between 5°C and 35°C. Keep away from direct sunlight, open flames, and moisture.
• Winter Protection: Do not allow the temperature to drop below 0°C, as freezing can cause the resin to emulsify or precipitate.
• Hardener Care (Crucial): 929-666 Hardener is highly sensitive to atmospheric moisture.
  • Always seal the cap tightly immediately after use.
  • If the hardener becomes cloudy, develops sediment, or crystallizes, do not use it, as it will cause loss of gloss, curing failure, or micro-blistering.

A: Orange peel is usually caused by incorrect spray gun setup or fast solvent evaporation. Ensure you are using a 1.3mm-1.4mm nozzle, maintaining a gun distance of 15-20 cm, and that your inlet pressure is at least 1.8-2.2 bar. In hot weather, adding a slow thinner will improve leveling and eliminate orange peel.

A: Once the clearcoat is fully cured (after 30 minutes bake at 60°C and cooling, or 10 hours air dry), wet-sand the defect area using P1200 to P2000 grit sandpaper. Once flat, polish the area with a high-quality cutting compound and a foam or wool pad to restore the high-gloss finish.

A: No. The pot life of the mixed clearcoat is 2 hours at 20°C. Once the clearcoat and hardener are mixed, the chemical crosslinking process begins immediately. Any leftover mixed paint will gel and harden, making it unusable. Clean your spray gun with thinner immediately after spraying.

A: Absolutely. For that ultra-deep "buried in glass" look popular on custom choppers and show cars, you can apply 2 coats of 923-666, bake or air dry completely, sand the surface flat using P800–P1000 wet sandpaper (ensuring you do not sand through to the color coat), wipe it clean, and then apply another 2 coats of 923-666. This "flow coating" technique yields an incredibly smooth, deep, and thick-looking finish with zero visible graphic or decal edges.

A: Solvent popping occurs when the top layer of the clearcoat skins over too quickly, trapping escaping solvents underneath. To prevent this in temperatures exceeding 30°C:

1. Use a slow-acting reducer/thinner (up to 10%) to keep the paint wet longer.
2. Extend your flash-off time between the first and second coat to 8–10 minutes.
3. Avoid applying coats too thick in a single pass.
4. Allow a full 15 minutes of ambient flash-off before turning on the bake cycle in your booth.

A: While you can mix pearls or candies into 923-666, we highly recommend using an intercoat clear or binder for your effect pigments, and keeping Glasurit 923-666 strictly as your final, pure protective topcoat. Mixing additives directly into the final clearcoat can alter its UV blockers and chemical crosslinking, which may reduce its scratch resistance and weatherability over time.

A: Don't panic—Glasurit 923-666 has excellent curing stability which makes repairs easy:

1. Allow the clearcoat to cure completely (preferably force-dried at 60°C and left to settle overnight).
2. Apply a dry-guide coat over the sag.
3. Wrap a block with P1200 or P1500 wet sandpaper and sand the run flat, checking your progress frequently.
4. Finish sanding with P2000 or P3000 to remove scratches, then compound and polish to restore the mirror gloss.

A: Yes, it is one of the best clearcoats for carbon fiber. Raw carbon fiber absorbs UV radiation, which can cause the underlying epoxy resin to yellow and degrade. Glasurit 923-666 contains high-concentration UV absorbers and light stabilizers that act as a sunblock, preventing both the clearcoat itself and the carbon fiber composite beneath from fading, yellowing, or delaminating.
