LKAB Minerals offers two main products to increase the fire retardancy of your coating:
Halogen-free Aluminium Trihydrate
In waterborne and solvent-based paints ATH can extend TiO2 thereby reduce production costs of the paint. The weathering resistance provided by ATH means it performs well in exterior coatings as well as interior. ATH also controls gloss in coatings making it suitable for a variety of applications including powder and roof coatings.
Halogen Free Huntite / Hydromagnesite
UltraCarb, a naturally extracted mixture of Huntite and Hydromagnesite, has a unique reaction to an increase in temperature, creating a three-stage fire retardant rocket between 220 and 500 degrees Celsius.
Especially in plastisols, it is a welcome addition because the carbonate fraction and the skeleton formation ensure smoke reduction (“acid smoke”).
As it is extracted as a mixture and does not require chemical/energy-intensive treatment, UltraCarb has a very favourable LCA compared to precipitated ATH.
Thanks to its high whiteness, UltraCarb can also be used as a TiO2 replacement and thus reduces the production costs of the paint.
High aspect ratio MicaFort
Cementitious fire-resistant coatings used for the protection of structural steel and concrete in commercial construction gain from MicaFort‘s high aspect ratio and thermal stability. This contributes to lower flammability whilst reinforcing the char to prevent coating failure during a fire.
Our team at LKAB Minerals is technically trained to help you select the right ATH, UltraCarb or MicaFort product. Contact one of our sales managers today for more detailed information, a sample or datasheet.
