Nearly half a century of proven success in protecting lives and assets
Ammonium polyphosphate is a powerful polymeric flame retardant made in Germany since 1975. As the basis of our Exolit® AP products, it can provide non-toxic fire safety properties to flame retardant and fire-resistant intumescent coatings as well as to other products.
A great team player in intumescent systems – with many additional benefits
High-quality additives such as our Exolit® AP 422, Exolit® AP 418 (TP), Exolit® AP 435 and Exolit® AP 462 products are vital parts of many intumescent systems and fire protection coatings. Thin layers of intumescent coatings enable fire resistance times of up to 4 hours, protecting load-bearing steel structures, cables, wood and plastics, as well as textiles and paper.
When used in intumescent systems or with synergists in various fiber reinforced thermosets or polyurethane foams, our products support solutions like light-weight composites for transportation and construction, and feature non-migration of the used flame retardant. Also capable of adding excellent flame retardancy to polyolefins, all Exolit® AP products are characterized by very low smoke density and a favorable health and environmental profile.

Based on more than 40 years of experience in the manufacturing of ammonium polyphosphate and its application in various fields Clariant has developed two new halogen-free flame retardants for water- and solvent-borne coatings. Exolit® AP 435 lowers your formulation viscosity, supports easy and constant production and product quality and keeps your water-based formulations flowable, even at low temperatures. Exolit® AP 418 (TP) improves the fire protection performance by offering an earlier on-setting reaction in solvent-based formulations.

Halogen-free, non-toxic, phosphorus-based solutions produced with 100% green electricity, of which several carry Clariant’s sustainability label EcoTain®
Compounds with a long track record, coming in a consistent quality that ensures steady production processes
Products available for waterborne, solvent-based as well as 2K-formulations, all being easily incorporated during the dispersion stage
Are Exolit® AP flame retardants a good fit for fire protection systems? Volker Thewes can warmly recommend them
»The development of new intumescent coatings for fire protection of structural steel is particularly complex. Therefore, the selection of environmentally friendly, halogen-free and sustainable flame retardants, like the Exolit® AP range, is essential!«
