Enclosures
The whole inside is taped; the outside is coated as usual.
Painting enclosures and panels — the tape peels off with no residue after the bake.
Cover the areas that mustn't be painted, spray, bake, and the tape peels straight off with no residue. High-temperature masking for enclosures, cabinets and all kinds of metal panels is exactly what green polyester tape is made for.
- 200 °C · 30 minutes
- Green polyester tape, no residue (data sheet)
- 70 °C · 3 days
- No residue on steel, aluminium or plastic (in-house test)
- 200 °C · 1 hour
- Polyimide tape, no residue (data sheet)
One strip of tape stays with the part through all four steps.
-
01 · On
The edge you lay down now is the line on the finished part.
-
02 · Coat
High-temperature coating or plating — the tape edge mustn't let the coating creep underneath.
-
03 · Bake
The oven reaches peak temperature, and the parts stay in it for a while.
-
04 · Off
Out of the oven, peel the tape off: a clean line, and no residue.
Enclosures, cabinets and all kinds of metal panels — masked the same way
Cabinets
The large inner surfaces are taped, then the cabinet is hung on the line and baked.
Metal panels
Where the panel needs to conduct, the bare metal stays clear — and the edge comes out sharp.
Up to 30 minutes at 200 °C, green tape; hotter or longer, polyimide tape
Both use silicone adhesive, and both peel off without residue.
Green polyester tape
When enclosures, cabinets and metal panels are coated at high temperature, it masks what stays bare; circuit-board plating uses it too. Peels off with no residue after 200 °C for 30 minutes (data sheet). After 3 days at 70 °C, no residue on steel, aluminium or plastic — it just takes a little more force to peel (in-house test).

About green polyester tape
Polyimide tape
Baking at 220 °C, or for an hour? Use this — green tape is rated to 200 °C and tested for 30 minutes. No residue after 200 °C for 1 hour (data sheet).

About polyimide tapeBoth tapes tested by SGS: all ten RoHS substances not detected, and halogen-free.
Choose the tape by the heat cycle, not by colour alone.
Start with your oven temperature and dwell time. Then compare the test conditions before you ask for a sample.
Is it a painting, coating or plating mask?
See the green polyester grades and the published no-residue result after 200 °C for 30 minutes.
Check green polyester tape →Does the part stay hotter for longer?
See the PI tape grades, rated to 220 °C, with no residue at 200 °C for 1 hour.
Check polyimide tape →Are you comparing peel figures?
Make sure the substrate, peel angle, speed and standard are the same before you compare the numbers.
Read the test method →Tell me about your oven, and I'll pick the tape.
“Coating or plating? What temperature, how long, and how many passes? That's all I need.”
