Granudan Sealer BN201 for Modern Composite Production
Granudan Sealer BN201 is a powerful water-based mold sealer that delivers effective surface protection across epoxy, polyester, and metal molds. Designed to close porosities and fine scratches, the sealer creates a semi-glossy protective film that strengthens mold durability and improves release performance. As a result, it meets the strict HSE requirements of today’s advanced production facilities.
Easy Application with Strong Results
Operators apply Granudan Sealer BN201 using a clean cotton cloth or mop, spreading thin layers evenly across the mold surface. After wiping off and curing, the surface becomes sealed and ready for further treatment with a slipcoat. Depending on the mold type, 3–4 coats are typically sufficient, while porous plugs may require more. Short curing times between layers and excellent thermal stability up to 280°C make this product highly efficient for daily use.
Proven Performance in the Wind Industry
Granudan Sealer BN201 is widely specified and tested within the wind turbine blade industry, where consistency and durability are crucial. In addition, many other FRP-based industries benefit from its reliable performance. Together with water-based release agents such as Aqua Slipcoat 506, Release 707, and Watershield, it forms Granudan’s dedicated water-based release system.
