Novol N91094 N-Range Hard 90-800 Standard Hardener – 500ml
The Novol N91094 Hard 90-800 is a professional-grade, standard-speed activator from the premium N-Range series. This 500ml unit is specifically engineered to pair with Novol’s top-tier clearcoats, including Superb Clear 8100 and Rock Clear 8200.
As a Standard Hardener, it is the "all-rounder" of the N-Range, designed to provide a perfect balance between open-time (flow) and curing speed at typical workshop temperatures (18°C – 22°C).
Key Features & Benefits
- Perfect Chemical Synergy: Formulated to cross-link specifically with N-Range high-solids (HS) resins, ensuring the clearcoat reaches its maximum laboratory-tested hardness and gloss.
- Optimized for 2:1 Systems: This 500ml bottle is the exact volume required to activate a 1.0-litre tin of Superb Clear 8100, creating a convenient 1.5L ready-to-spray mixture.
- Balanced Evaporation: Provides enough "wet time" for the clearcoat to level out (reducing orange peel) while ensuring a fast enough through-cure to minimize dust inclusion.
- Crystal Clarity: High-purity formulation ensures that the hardener does not tint or yellow the clearcoat, maintaining the "water-white" transparency required for silver and white paintwork.
- Consistent Gloss Retention: Prevents "die-back" (loss of shine during curing) by ensuring a stable and uniform chemical reaction throughout the paint film.
- Superior Chemical Resistance: Once cured, it helps the clearcoat resist fuel spills, bird droppings, and harsh weather conditions.
Professional Mixing Pro Tips
- The 2:1 Ratio: Always use a Novol N-Range 2:1 Measuring Stick. HS (High Solids) clears are extremely sensitive to mixing ratios; even a 5% error can lead to a finish that remains soft or becomes overly brittle.
- Stirring: After adding the 500ml of 90-800 to your clearcoat, stir thoroughly for at least 60 seconds, ensuring you scrape the bottom and corners of the mixing cup.
- Pot Life: Once mixed, you have approximately 2 hours at 20°C to spray the product. In warmer environments, this window will shorten significantly.
- Storage: Keep the cap tightly sealed when not in use. This hardener is moisture-sensitive; exposure to humid air will cause it to "clump" or lose its potency.
Why Choose the 90-800 Standard Hardener?
In a standard bodyshop environment, the 90-800 is the go-to choice. While "Fast" hardeners are great for small spot repairs, they can dry too quickly on large panels (like a hood or roof), leading to a "dry spray" finish. The Standard 90-800 gives the Clearcoat the time it needs to "flow" into a glass-like finish while still allowing you to de-mask and handle the parts within a few hours.
