Novol N91564 N-Range Hard 90-860 – Standard Hardener for Mega Clear, 500ml
The Novol N91564 Hard 90-860 is a high-performance activator specifically engineered for the N-Range Mega Clear 8600 (N91563). This 500ml unit is the essential chemical partner required to trigger the "Mega" fast air-drying properties of the 8600 resin system.
Unlike standard 2K hardeners, the 90-860 is formulated to catalyze the clearcoat through a rapid reaction with atmospheric moisture and air, allowing for a "bake-quality" finish at room temperature.
Key Features & Benefits
- Optimized for Air-Drying: Specifically designed to work with the unique resins in Mega Clear 8600, enabling the clearcoat to reach polishing hardness in as little as 60–90 minutes at 20°C.
- Crystal Clear Finish: High-purity solvents ensure the mixture remains water-white, preserving the true color of the basecoat without yellowing or cloudiness.
- Superior Gloss Retention: Helps the clearcoat maintain a "wet-look" depth during the rapid drying phase, preventing the surface from "dying back" or losing its shine.
- Enhanced Chemical Linkage: Creates a dense molecular structure that provides the final finish with excellent resistance to scratches, UV rays, and environmental pollutants.
- Convenient 500ml Size: Perfectly measured to activate a 1.0-litre tin of Mega Clear 8600 at the required 2:1 mixing ratio.
- Excellent Leveling Support: Allows the clearcoat just enough time to flow out smoothly before the rapid curing process locks the film in place.
Professional Mixing & Handling
- The 2:1 Ratio: Use a Novol N-Range 2:1 Measuring Stick. Because this is a high-speed system, being "close enough" with the ratio isn't enough; precision ensures the rapid-dry technology functions as intended.
- Mixing Speed: Once you add the 90-860 to the clearcoat, stir immediately and thoroughly. The chemical reaction begins the moment they touch.
- The "Pot Life" Warning: With a pot life of roughly 60 minutes, only mix the amount you can comfortably spray in one session. Do not leave this mixture sitting in your spray gun during a lunch break.
- Airtight Storage: Hardener 90-860 is extremely sensitive to humidity. Always replace the cap immediately after pouring to prevent the product from "seeding" or hardening inside the tin.
Why Is the 90-860 Hardener Essential?
The Mega Clear 8600 system is designed to save you time and energy by eliminating the need for a heated spray booth. However, that technology relies entirely on the N91564 Hardener. Using a standard hardener (like the 90-800) with Mega Clear will result in significantly slower drying times and may compromise the final gloss and durability.
