Superseded in 1997 · still on many drawings
MIL-C-20696E coated cloth
The older revision of the coated-cloth spec, still called out on a lot of drawings and contracts.
MIL-C-20696E was issued in 1987 and replaced by MIL-PRF-20696 in 1997, but buyers still order to it. Unlike the newer spec, it names the polymer for each class: chloroprene rubber for Class 1 and Class 3, and fire-retardant vinyl for Class 2.
Both faces get coated, with the face side coated heavier than the back on most types. The spec's own guidance points to chloroprene when the cloth has to flex at −40°F.
We quote Class 2 vinyl now. Classes 1 and 3 call for chloroprene, which returns with our waterborne system in 2027. A waterborne chloroprene latex is still chloroprene rubber, which is what the spec asks for.
What we build
- Class 2 vinyl on nylon or polyester
- Chloroprene Classes 1 and 3 (2027 program)
- Widths up to 64 in
Questions buyers ask
Do you make MIL-C-20696 Class 1 or Class 3 today?
No. Those classes call for chloroprene, which we're bringing back as a waterborne system in 2027. Send your requirements and we'll add your program to the list.
Why does the old revision still matter?
Drawings and contracts written before 1997 still cite it. The polymer requirements in E are stricter than in MIL-PRF-20696, so the callout decides which build is acceptable.
Spec summaries are for orientation only. The current revision in your contract governs. Send your type, class and drawing and we'll confirm fit, testing and paperwork before we quote.
