Out of the fire with new fire-resistant coating

Natural character of wood is retained

Whether it's a school, a factory hall or an apartment building: wood is the building material of the moment. And that brings with it new challenges, for example in the area of fire safety. With the fire protection coating Pyrolan Expand, the Austrian paint and lacquer manufacturer ADLER has now developed a versatile, reliable and environmentally friendly solution for this.

Pyrolan Expand, a coating for interior spaces, is easy to apply and available in numerous color shades. The coating is completely water-based and contains no formaldehyde, biocides, heavy metals or halogens, so that no toxic substances can be released in the event of a fire. In addition, Pyrolan Expand meets B-s1, d0, the best fire safety classification according to European standard EN 13501-1 possible for combustible building materials such as wood and wood-based materials. 

In the primer Pyrolan Expand Base, different raw materials are combined with each other in an innovative way. This creates a layer of carbon foam at high heat, approximately 300 degrees. This forms an insulating layer on the wood and protects it from the flames. This significantly slows the onset and spread of a fire. 

Pyrolan Expand can be applied by spray, brush or roller. "When the coating is sprayed, two passes are sufficient: first the primer Pyrolan Expand Base is applied, followed by the top coating Pyrolan Expand Top," says Leon Cremers, director of ADLER Benelux. 

This top coat ensures that the fire-resistant function is retained for a long time and protects the wood from damage and dirt. In addition, Pyrolan Expand offers great scope for creativity: "In the glaze variant, we have optimized the color for numerous common wood species
to preserve the natural appearance of the wood. In addition, Pyrolan Expand is also available in different colors as an opaque variant," says Cremers. He sees great potential for the new coating: "The fact that Pyrolan Expand provides high fire safety while being able to retain the natural character of the wood opens up new possibilities for modern wood construction."
