Water-based intumescent coating designed for the fire protection of structural steel. Thin film intumescent coating that creates a fire retardant and fire resistant barrier on a wide range of building surfaces including gypsum, wood, and steel.
How it works
Mascoat WeatherBloc-HRC thermally protects a structure from heat in multiple ways unlike reflective rooftop coatings, which only reflect sunlight to reduce solar loading. Its bright white coloring reflects upwards of 85% of the solar radiation like standard reflective coatings, but there’s more to the coating than just coloring. It also contains irregularly-shaped ceramic particles that help greatly reduce the amount of heat transfer through the coating. This high content of entrapped air blocks thermal transfer very efficiently. While reflective coatings only recommend one coat because they are solely relying on reflective properties, an extra coat of WeatherBloc-HRC will give you enhanced performance. The coating will help reduce heat transfer even if it becomes dirty or is placed on the underside of a roof! The combination of these factors allows for enhanced thermal dissipation across the surface of the coating. WeatherBloc–HRC’s unique composition makes it extremely efficient for its thickness, resulting in less thermal transfer into interior spaces than standard reflective coatings.
