- Safe and simple handling due to its paste form, making processing easier
- The thixotropic nature hinders the sedimentation process and simplifies rehomogenisation after long storage periods
- Developed as a flame retardant for epoxides
- Very effective flame retardant due to its high phosphorus content
- Non-halogenated flame retardant with favorable environmental and health profile
As stated in the safety data sheet of the substance the use “industrial manufacture of screening smoke ammunition or smoke payloads” is advised against within the EU according to the REACH regulation. Therefore, every manufacturer of smoke ammunition or smoke payloads is obliged to create a chemical safety assessment for these uses and to inform the ECHA accordingly.

Red Phosphorus and aluminum hydroxide have a synergistic flame retardancy effect. When combining Exolit RP 6500 with aluminum hydroxide a UL 94 classification of epoxy casting resins can be achieved with low amounts of fillers.
Exolit RP 6500 is supplied in the following packaging:
1 kg sample bottles
50 kg net plastic drums
200 kg net steel drums
After long storage periods, in particular at low temperatures, rehomogenisation will be necessary and should be done by stirring at room temperature or better elevated temperature (50°C - 80°C).
Minimum shelf life is 12 months from the date of shipping when stored according to the said conditions.
