German term

Porendichtigkeit

German to English Tech/Engineering Chemistry; Chem Sci/Eng
Document is about the properties of flouroplastics. I found "coating holdout" and "coating porosity" as possible translations but am not sure which one, if any of them, would be correct. I appreciate your help!
Proposed translations (English)
3 +2 pore impermeability
4 +1 pore tightness
4 (coating) holdout
3 -1 pore density

hazmatgerman (X) Dec 18, 2008:
It would help if made clear whether the density of pores (i.e. average size and distribution) or their resistance to penetration is the issue here. I suspect the former. The term in German would then better be "Porendichte".
Marion Rhodes (asker) Dec 16, 2008:
It's an anticorrosive coating for industry parts.
Ingeborg Gowans (X) Dec 16, 2008:
do you have any idea how this material is going to be used? I found the connection w/ dentures etc. w/ googling?
Marion Rhodes (asker) Dec 16, 2008:
Unfortunately, there is no sentence. It is part of a table, just this one word, and defined only with the indicator "tested at 6kV."
Andrea Winzer Dec 16, 2008:
Could you please give us the whole sentence in German.

pore impermeability

Pore impermeability was also tested using a high voltage ( 10 KV) pore detector in conjunction with a broom electrode, the number of disruptive discharges being measured 15 Since this test is dependent upon the applied layer thickness, test plates with an applied PVDF layer thickness of 750 gm were also tested.

Note from asker:
Hmmh, maybe impermeability by itself is what I need. I found this link: http://www.iop.org/EJ/article/1468-6996/4/4/A03/STAM_4_4_A03.pdf?request-id=6f07b48a-81d8-41f6-9293-07b8c5ad0d9c "For 6 years, we have developed corrosion resistant coatings to protect steel structures in the marine environment by using a thermal spray technique. This paper summarizes the major developments and results obtained. Such a coating requires primarily impermeability and secondarily homogenous and clean microstructure."

agree Johannes Gleim : not bad, either, even Google produces only 2 hits. http://www.gutbrod-ptfe.de/process_sequence.html?&L=2

3 KudoZ points awarded for this answer. Comment: "I am going to go with plain "impermeability." This word produces a lot of google hits in my context. Thanks for pointing me in the right direction!"

pore density

Peer comment(s):
disagree Sabine Akabayov, PhD : Dichtigkeit is not the same as density; that you find Google hits for both terms independently doesn't proof anything

(coating) holdout

nach: Langenscheidt Fachwörterbuch Technik und Angewandte Wissenschaften

"coating holdout" (= resistance to penetration) is a little more general than coating porosity. The holdout depends on the porosity but also on other parameters like roughness of the surface.
Peer comment(s):
neutral Johannes Gleim : I do not think that resistance to penetration (Eindringwiderstand) is appropriate as translation of Porendichtigkeit. Porendichtigkeit implies that the pores are sealed.

pore tightness

the resultant film is very tight-pored and waterproof.
..
The coating obtained from this additional special composition has a high pore tightness, high elasticity and high strength of adherence.
http://www.freepatentsonline.com/4567230.html

The alternative "pore-tightness-check" method (spark inductor test) turned out to be a cost-saving and safe test method compared with the conventional water impact. Using this method, a tightness check can be made directly after the completion of the sealing, shortly before tiling work.
http://www.bauwerke-abdichten.de/english/feuchtigkeit4.htm

Pore tightness of the plastics coating means that commercially available magnesium or aluminium alloys with no special additives can be used for the castings so that the price of the casting can be substantially reduced.
...
The plastics coating is then hardened out at about 2000C and forms a pore- and pressuretight coating on the surfaces.
http://www.wikipatents.com/gb/1554791.html

Note to 6 kV tested: This is obviously a dielectric withstand test (electrical strenght) and relates only indirectly to the pore tightness.

Grazie!
neutral hazmatgerman (X) : I tend to agree but would want to wait for clarification by asker.
