Novol N35621 Novakryl H5110 Fast Hardener – 500ml
The Novol N35621 Novakryl H5110 is a professional-grade Fast Hardener designed specifically for use with the Novakryl 510 Acrylic Clearcoat. This 500ml unit is the ideal activator for spot repairs, small panel work (like a single door or wing), or for use in colder workshop conditions where a standard-speed hardener would take too long to cure.
As a Fast variant, it is engineered to accelerate the cross-linking process, reducing the "dust-dry" time and allowing for quicker polishing and assembly.
Key Features & Benefits
- Accelerated Curing: Significantly shortens the drying cycle, making it the perfect choice for "smart repairs" where a fast turnaround is required.
- Cold Weather Performance: Ideal for use in ambient temperatures between 15°C and 18°C, where standard hardeners may struggle to "flash off" correctly.
- Crystal Clarity: Formulated to maintain the high transparency of the Novakryl 510 clearcoat, ensuring no yellowing or clouding of the basecoat color.
- High-Gloss Retention: Despite the faster chemical reaction, it is designed to prevent "die-back," ensuring the clearcoat retains its mirror-like finish after drying.
- Reduced Dust Inclusion: Because the clearcoat skins over faster, there is a much smaller window for airborne dust and lint to settle into the wet paint.
- Optimal 2:1 Ratio: This 500ml bottle is perfectly sized to activate a 1.0-litre tin of Novakryl 510 Clearcoat, creating 1.5 litres of ready-to-spray product.
Professional Mixing & Application Tips - The 2:1 Ratio: Use a Novol 2:1 Measuring Stick. Precision is key; over-catalyzing with a fast hardener can make the paint brittle, while under-catalyzing will leave it soft.
- Short Pot Life: Because this is a Fast hardener, the "pot life" (the time you have to spray before it thickens in the gun) is shorter than standard hardeners. Only mix what you can spray immediately.
- Application: Apply in two coats. Ensure a 5-minute flash-off between coats. In very warm weather (above 22°C), use caution as a fast hardener can cause "dry spray" on large panels.
- Airtight Storage: Like all 2K hardeners, H5110 is highly sensitive to moisture. Always replace the cap immediately after pouring to prevent the product from reacting with the humidity in the air.
Why Choose the H5110 Fast Hardener?
If you are painting a full car in a heated booth, a standard hardener is usually best. However, for small repairs or mobile technicians working in variable temperatures, the Novol H5110 Fast Hardener is essential. It gives you the confidence that the paint will be "out of the wind" and hard enough to handle in a fraction of the time, keeping your project moving forward.
