Novol Novakryl H5120 Standard Hardener – 500ml (N35631)
The Novol Novakryl H5120 Standard Hardener is a high-performance universal activator designed specifically for use with Novol’s premium 2K acrylic clearcoats, including Novakryl 570, 580, and 590. This 500ml standard-speed hardener is engineered to provide a balanced curing rate, ensuring excellent flow, leveling, and a crystal-clear, high-gloss finish.
As a "Standard" speed hardener, the H5120 is the most versatile choice for general workshop conditions, performing optimally at room temperatures between 18°C and 25°C.
Key Features & Benefits
- Universal Compatibility: Specially formulated to work seamlessly with the Novakryl series (HS and UHS clearcoats), ensuring consistent chemical cross-linking.
- Optimal Flow & Leveling: Allows the clearcoat enough "open time" to level out perfectly, virtually eliminating "orange peel" for a glass-like finish.
- High Gloss Retention: Ensures the clearcoat cures to its maximum brilliance and depth, maintaining that "wet look" long after drying.
- Weather & UV Resistance: Activates the protective properties of the clearcoat, shielding the paintwork from UV degradation, bird droppings, and industrial fallout.
- Stable Curing Profile: Provides a predictable drying window, making it ideal for both individual panels and full-body resprays.
- Professional Grade: Formulated for high-build (HS) systems, providing a tough, scratch-resistant surface once fully cured.
Application Guidelines
- Mixing Ratio: Always follow the specific ratio for the clearcoat you are using (typically 2:1 or 5:1 depending on the specific Novakryl product).
- Agitation: Mix the hardener and clearcoat thoroughly. Improper mixing can lead to "soft spots" or a loss of gloss.
- Pot Life: Be mindful of the pot life (working time) once mixed, which is generally 2-4 hours at 20°C.
- Safety: This product contains isocyanates. Always wear a high-quality respirator (fed-air or carbon filter) and appropriate PPE during application.
Why Choose H5120 Standard?
While "Fast" hardeners are great for small spot repairs, they can dry too quickly on larger surfaces, leading to "overspray" or dry edges. The Novol H5120 Standard Hardener is the professional's choice for achieving a uniform, high-quality finish across large areas, giving the painter total control over the application process.
