Glasurit 923-666 High Solids VOC Clear Coat is a premium two-component polyurethane clear coat for automotive refinishing in basecoat/clearcoat systems. Supplied in a 5L clear coat format, it is designed for high-quality repair work on passenger vehicles, commercial vehicle exterior panels, complete-panel refinishing, and premium spot repairs.
When mixed with the specified Glasurit 929-666 VOC Hardener at a 2:1 volume ratio, the system offers a high-solids application profile, high-gloss appearance, strong film build, and flexible drying options.
The recommended process uses two coats, with approximately 3 minutes flash-off between coats at 20°C. The product may also be applied using the ½ + 1 vertical-panel method where permitted by the relevant product instructions.
The high-solids formulation helps achieve the specified dry-film build with efficient material use and fewer unnecessary spray passes.
Designed to produce a transparent, high-gloss clear layer that enhances color depth, metallic effect, and pearl appearance beneath it.
The clear coat is intended to create a full-bodied, visually deep finish suitable for premium automotive repair and refinishing work.
At 20°C, the recommended flash-off time is approximately 3 minutes between coats, supporting efficient booth workflow.
The system supports air drying, force drying, short-wave infrared drying, and medium-wave infrared drying, allowing body shops to match the process to their equipment and repair cycle.
The recommended ½ + 1 application method is designed for vertical-surface work where application control and film appearance are important.
Suitable for collision repair, full-panel refinishing, luxury vehicle repair, and premium customization projects where finish quality matters.
Designed for automotive basecoat/clearcoat systems, including use over suitable Glasurit basecoat systems according to the applicable technical instructions.
After proper curing and cooling, the finish is suitable for corrective polishing as required in professional refinishing processes.
The ready-for-use VOC value is stated as ≤419 g/L. Compliance requirements vary by jurisdiction; buyers should confirm local regulatory acceptance before import or use.

923-666 is positioned in the premium HS clear-coat segment alongside products such as PPG DC-series clear coats, Spies Hecker Permasolid HS clear coats, and Sikkens Autoclear HS systems. Its commercial value is its fit within the Glasurit refinishing ecosystem, particularly for workshops seeking a high-gloss, high-film-build finish and flexible drying routes.
Claims of cross-brand compatibility, final appearance, scratch resistance, or regulatory conformity should always be confirmed through the relevant current technical documentation and local testing.
Ensure the basecoat is fully flashed according to its own technical data sheet. The surface must be clean, dry, free from dust, silicone, oil, and other contaminants.
Mix 2 parts 923-666 Clear Coat with 1 part 929-666 Hardener by volume. Mix thoroughly before spraying.
Use the activated material within approximately 2 hours at 20°C. Higher temperatures can reduce usable working time.
Use an HVLP spray gun with a 1.3–1.4 mm nozzle. Set spray pressure to 2 bar and fan air pressure to 0.7 bar, subject to gun manufacturer requirements.
Apply two coats to achieve a recommended final dry-film thickness of 40–60 μm.
At 20°C, allow around 3 minutes flash-off between coats. For approved vertical-panel use, follow the ½ + 1 application method specified by the product documentation.
Choose air drying, 60°C force drying, short-wave infrared, or medium-wave infrared according to your workflow and equipment.
After force drying or infrared curing, allow the panel to cool before polishing. Avoid aggressive polishing before the coating has developed sufficient cure.
| Issue | Possible Cause | Practical Check |
|---|---|---|
| Orange peel | Incorrect viscosity, poor atomization, incorrect gun setup | Confirm viscosity, pressure, nozzle size, and application distance |
| Runs or sags | Heavy coats, excessive film build, insufficient technique control | Apply consistent coats and observe film wetness |
| Solvent popping | Excessive film thickness or unsuitable flash-off | Follow coat count, flash-off, and drying instructions |
| Dust inclusions | Poor booth cleanliness or inadequate tack wiping | Clean work area and use suitable tack cloth procedures |
| Loss of gloss | Improper cure, contamination, unsuitable basecoat condition | Confirm basecoat flash-off, drying conditions, and contamination control |
| Dieback after polishing | Insufficient curing before finishing | Allow adequate air-dry or bake cycle before polishing |
