Alka 204 Clear
UV Stable Polyaspartic Topcoat
Alka 204 is a great option for many uses, including Decorative Flake systems, Epoxy self-levelling floor toppings, and decorative flooring finishes for both indoor and outdoor areas.
Advantages
Alka 204 has a lot of advantages, making it an outstanding option for a variety of applications. It delivers an exceptionally bright, clear, and transparent finish, ensuring surfaces maintain their radiant appearance. Thanks to its low viscosity, applying it becomes effortless, facilitated by its smooth consistency.
Furthermore, Alka 204 exhibits exceptional toughness and durability, guaranteeing long-lasting protection. Its outstanding bond strength ensures robust adhesion to surfaces, while its versatility permits users to apply it with either a brush or roller, offering flexibility. With its ultra-high solids content, it achieves superior performance, safeguarding new concrete from damage and revitalizing worn surfaces to a smooth finish.
Application
For application, aim for a coating thickness of approximately 25 microns per coat. The pot life at 25°C lasts for at least 1 hour, providing sufficient time for application. At the same temperature, curing time entails achieving touch dryness within 1 hour, with re-coating possible after 6-8 hours. Light traffic can resume after 3 days, and full cure occurs within 7 days, ensuring a durable and resilient finish.
Consumption
Substrate conditions typically dictate the application rate, ranging from approximately 0.1 to 0.15 kg/m2 (around 5-8 m2/litre) per coat. Additionally, users typically apply two coats as a concrete sealer to achieve a total thickness of 25 microns.
Application Instructions
Alka 204 can be applied by brush, roller, or spray. Please note that Alka 204 has a special solvent, and normal Xylene solvents must not be used for thinning.
Cleaning of Equipment
Use Xylene to clean tools and equipment before the mixed compound begins to harden. Once cured, you can only remove it mechanically.
