Xylan Thyme Green Mould Release Coating
AST applies Xylan “Thyme Green” thin-film dry-film coating to production moulds for Wagma Engineering — a precision engineering and toolmaking business. Consistent release, dimensions intact.
Mould release is a thin-film problem. The coating has to change how the part comes out of the cavity without changing the cavity itself, which rules out the heavier-build systems AST applies elsewhere for chemical barrier or wear duty. Selecting the film build is the whole decision — see our Xylan coating services page for the full grade detail.
Release performance without losing tolerance
Production moulds have to do two things that pull against each other: release cleanly, and hold dimension. A release coating that builds thickness changes the cavity, and on precision tooling that is not acceptable. The customer needed consistent release across its production moulds without giving up the tolerances the tooling was cut to — and, because some of that tooling runs in food production, needed a release system with the right materials status behind it.
- Consistent release across production moulds
- Critical mould dimensions must be preserved
- Food-production tooling in the same set
- Mould sets rotate through refurbishment
Thin film, controlled build, repeat cycle
AST applies Xylan “Thyme Green” as a thin-film dry-film coating on the mould surfaces. Moulds are prepared, coated to a controlled film build and cured. Because the system is thin-film, the dimensional effect on the cavity is minimal — which is precisely why it was specified over a heavier-build alternative. Mould sets rotate through the program as they come out of service for refurbishment, so the work runs as a repeat cycle rather than a single job.
- Controlled preparation and film build
- Thin-film application on mould surfaces
- Specified over heavier-build alternatives
- Repeat cycle as mould sets are refurbished
Xylan “Thyme Green”
Xylan “Thyme Green” is a PTFE-rich solvent-borne dry-film coating from the Whitford / PPG Xylan family, applied at approximately 20–40 µm. It is FDA-acceptable, which makes it suitable for tooling used in food production, and its thin film is what preserves critical mould dimensions.
- PTFE-rich solvent-borne dry-film system
- Approximately 20–40 µm film build
- FDA-acceptable — suitable for food-production tooling
- Whitford / PPG Xylan family
Moulds back in production, on a repeat program
The moulds return to production with consistent release, and the work now runs as a repeat program as mould sets cycle through refurbishment. Each job is processed to the same specification with documented QA, a turnaround of 7–10 working days from receipt, and AST's lifetime workmanship warranty.
- Consistent release on returned moulds
- Ongoing repeat program
- 7–10 working days from receipt
- Lifetime workmanship warranty
AST applies the Whitford / PPG Xylan range alongside its Chemours fluoropolymer systems, so the release system is selected on duty — film build, materials status and dimensional tolerance — rather than on what happens to be in stock.
