Orgasol® powders can also be used as smoothing agent to help reduce the coefficient of friction and add lubricity to the final coating. These REACH-compliant polyamide powders are manufactured without the use of PFOA or any other PFAS, so they make an excellent alternative to PTFE waxes. Now formulators have a great alternative to PTFE waxes for reducing the coefficient of friction/slip aid and improving abrasion resistance while staying compliant with the changing regulatory landscape.
Coefficient of friction
As you can see in the chart below, a small amount of Orgasol® powder reduced the dynamic coefficient of friction to a similar level as that of the PTFE/PE wax evaluated. Additionally, the Orgasol® powder at the same time imparts other great properties like abrasion resistance, gloss control, and stain & chemical resistance. So when you need lubricity in addition to other properties, Orgasol® powders are a great option.

PTFE wax alternative
Why should you consider looking for an alternative to PTFE wax?
- Certain PTFE waxes are produced with the use of PFAS surfactants
- Because Orgasol® powders are manufactured without the use of PFOA or any other PFAS, these polyamide powders are compliant with European Union REACH Annex XVII (as of 4 July 2020). This provides formulators with an alternative slip aid additive that also improves abrasion resistance while remaining compliant to current regulatory requirements.
