Novol N65411 Classic Hardener – For Polycoat Protect (5:1), 700ml
The Novol N65411 Classic Hardener is a professional-grade activator specifically formulated for the Novol Polycoat Protect series. This 700ml unit is the essential second component required to trigger the chemical curing process of high-build protective coatings. Engineered for a precise 5:1 mixing ratio, it ensures that the base coating achieves its maximum mechanical strength, chemical resistance, and "shield-like" durability.
When combined with Polycoat Protect, this hardener facilitates a thorough "through-cure," preventing surface tackiness and ensuring the coating remains stable under extreme environmental stress.
Key Features & Benefits
- Optimized for Polycoat Protect: Tailored to the specific resin chemistry of Novol’s heavy-duty protective line, ensuring a perfect molecular bond.
- Superior Hardening Properties: Transforms liquid coatings into a rugged, impact-resistant finish that protects against stone chips, abrasion, and road debris.
- Precise 5:1 Mixing Ratio: Designed for ease of use in professional mixing environments, providing a predictable working time (pot life).
- Weather & Chemical Resistance: Activates the coating’s ability to repel water, salt, oils, and UV radiation, making it ideal for chassis and underbody applications.
- 700ml High-Value Volume: Perfectly measured to match standard Polycoat Protect base quantities, minimizing leftover waste.
- Consistent Leveling: Helps maintain the intended texture and flow of the coating, whether you are aiming for a smooth or "stippled" industrial finish.
Application & Mixing Guidelines
- Precision Mixing: Use the Novol N39699 (4:1 / 5:1) Measuring Stick. Because Polycoat systems are highly structural, an exact 5:1 ratio is critical to prevent the coating from being too brittle or too soft.
- Stirring: Add the hardener to the base and stir vigorously for at least 2 minutes. Ensure you scrape the sides and bottom of the mixing container.
- Flash-off: If applying multiple coats, allow for the recommended flash-off time (usually 10–15 minutes) to ensure solvents escape before the next layer is applied.
- Safety: This product contains isocyanates. Always wear a high-quality respirator and protective gloves during mixing and application.
Why Choose the N65411 Hardener?
Heavy-duty protective coatings are only as strong as their catalyst. The Novol N65411 is engineered to handle the "heavy lifting" of industrial and automotive protection. By using the dedicated Classic Hardener, you ensure that the Polycoat Protect system provides the long-term anticorrosive barrier it was designed for, even in the harshest climates.
