CHERRY WetEx — Protective Keyboard Film for the G84-4100, 86 keys
Model specificChemical resistant10M+ cyclesLatex free
A keyboard in a workshop, a laboratory or a production hall does not fail from typing — it fails from what lands on it. WetEx is CHERRY’s answer: a flexible protective film laid over the keys that keeps dust, dirt and liquids out while you carry on working. CHERRY publishes the chemistry rather than a vague claim: it is resistant to distilled water, diesel, dishwashing liquid and isopropyl alcohol, and conditionally resistant to petrol, oil and 40% sulphuric acid (battery acid). The material is free of halogens, latex and does not contain polybrominated diphenyl ethers — which matters in food, medical and electronics environments where those are restricted. On durability CHERRY states that under normal conditions WetEx provides more than 10 million operating cycles. This film is cut for the CHERRY G84-4100, 86 keys.
Compatibility — check before buying:
The single thing to get right: WetEx films are cut for one specific keyboard model. CHERRY publishes 26 different WetEx part numbers, each matched to a different board, and a film for another model will not sit correctly over the keys — the cut-outs and the key spacing simply will not line up. This one fits the CHERRY G84-4100, 86 keys; if your keyboard is a different model, tell us and we will find the matching part number rather than sending the wrong film. Two more practical points. The conditional resistances are conditional for a reason: petrol, oil and battery acid will be survived but not indefinitely, so wipe them off rather than leaving them. And a film changes the feel of typing slightly — keys are covered rather than bare, which is the trade every protected keyboard makes. CHERRY publishes no thickness, no weight and no colour for the WetEx films, so we quote none.
Best For
✓ Workshops, garages and production floors
✓ Laboratories and medical environments
✓ Kitchens and food-handling areas
✓ Dusty sites where keyboards clog
✓ Shared keyboards that get disinfected
✓ Anyone who has already lost a keyboard to a spill
Key Features
Chemistry, not adjectives
CHERRY lists what it resists and what it only conditionally resists — diesel and isopropyl outright, petrol and battery acid with limits. Most covers claim nothing this specific.
Ten million cycles
A published durability figure under normal conditions, so the film is specified to outlast a long service life rather than being treated as disposable.
Halogen and latex free
No halogens, no latex, no polybrominated diphenyl ethers — the restrictions that actually come up in medical, food and electronics procurement.
Cut for the keyboard
A model-specific film rather than a universal sheet, so the keys stay usable and the edges do not lift.

Frequently Asked Questions
Will it fit my keyboard?
Only the CHERRY G84-4100, 86 keys. WetEx films are cut per model and CHERRY publishes 26 different part numbers. Tell us your exact keyboard and we will find the right one rather than sending a film that does not line up.
Does it change how the keyboard feels?
Slightly, yes — you are typing through a film rather than on bare keys. That is the trade every protected keyboard makes, and in the environments WetEx is built for it is a trade worth making.
What does conditionally resistant mean?
That petrol, oil and 40% sulphuric acid will not destroy the film on contact, but will damage it over time. Wipe them off rather than leaving them sitting on the surface.
Singular Expert Insight
Buy this the day before you need it, not after. A film is cheap; a keyboard killed by coolant, flour or disinfectant is not, and CHERRY is unusually specific about exactly which liquids it will survive. Get the model right. See our
