PFAS-free precote® 85 now available at Inlex Locking
Posted on Sep 10, 2025The innovative new thread locking coating precote® 85 PFAS-free is now available at Inlex Locking.
Inlex is the UK’s leading authorised certified coating partner for the precote® range of materials, which are manufactured by omniTECHNIK Mikroverkapselungs GmbH, part of the SurTec Group.
Inlex is proud to offer a wide range of precote® finishes – now including the reformulated precote® 85.
PFAS (per- and polyfluoroalkyl substances) substances, including PTFE (polytetrafluoroethylene), have been widely used in thread coatings due to their excellent frictional and thermal properties.
However, their environmental persistence and potential health impacts have led to increasing regulatory scrutiny – and OEMs are consequently phasing out coatings that contain PFAS.
In the new-look precote® 85, the PTFE content has been eliminated and replaced with an improved environmentally friendly biodegradable wax content which provides the same level of high performance.
Gareth Lowndes, Technical Sales Manager at Inlex, said: “We have partnered with omniTECHNIK for many years and continue to work closely with their team.
“precote® 85 has been a popular solution for some time, offering high performance locking of threaded parts.
“This reformulated version of the product offers the same exceptional performance, but without the presence of PFAS. Our customers are becoming increasingly environmentally conscious so will be pleased to be able to utilise this option.”
Products across the precote® range are used throughout many market sectors. Inlex also offers the proven high-strength thread locking adhesives precote® 30 and 80, along with the -3 (fast-curing) or -8 (for <M6 or fine-pitch components) versions to suit specific application requirements.
From the sealing product range, Inlex can offer pre-applied thread sealants like precote® 5 plus underhead sealants such as precote® 15 and 200, as well as precote® Top 300 pre-applied wax-based lubricants.
Gareth added: “We work closely with our partners as part of our joint ongoing commitment to continually develop new application and technological advancements to meet the current global trends and ever-changing requirements of both our customers and wider market sectors.”
