Blocking pads for Super Hydrophobic Lenses

[bbatts]

We have recently purchased an edger and are looking for the best pads to use with Super Hydrophobic AR lenses(Teflon, Pentax ECP).....I have been using some old 3M pads and would really like to find somthing better!!

Any Suggestions??????

We put small round surface blocker tape on the front side before blocking and then one on the back before we edge and do not have any trouble with slipage. hope this helps.

Which blocking system are you using? Flexible blocks or rigid?

[bbatts]

We are using rigid blocks, the real problem that I am having is not slippage, it is getting the block to stay on long enough to retouch if needed, the blocks are coming off easily.

pad and block coming off the lens in one piece

[Ginster]

This is the only way I"ve been able to keep the block and the pad on the lens, use that small round surface tape on the lens before you block it up then a peice on the back to keep it from spinning on the back of the lens. this is avial. were you purchase your leak pads it comes on a roll like the larger surface tape does only its small round dots enough for an edger block, We get ours at BPI. Also when you order the lenses with A/R from the lab they usually send you the tape to apply before blocking and a peice for the back of the lens.:)

secure edge plus, with antislip stickers on both sides.

Caveat, I only edge Avance' as it is the only superduperA/R we sell

Edger: Optronics 6E (yes just a plain ole 6E)

Blocking system 3M AIT solid blocks

Pads, 3M 1700M

Routine: Block-up directly pad to bare lense, place 3M blue chip on the back surface of lense.

The only time I have slippage problems is when the cutter blade starts to get dull.

I use DAC's HydroEdge Pads for all of our hydro/oleophobic lenses.

These pads work great by themselves with no stickers or additions required.

The only downside to these is the fact that the adhesive will let go almost as soon as the chuck pressure is released. Make sure your edger is on size!!!!!

we use hilco oleophobic blocking pads

The Secure Edge pads worked reasonably well for me, but still had some slippage. What I disliked the most tho was the amount of time it took to clean (and reclean) the lenses afterword.

I now use, with incredible success:
Clean all lenses first (except Alize)
Front side gets clear surface saver tape with blocking pad mounted on it
Blocking pads are PSI #2810
Back side gets an extra pad if it is AR/polarized/photochromic/otherwiseExpensive
Let sit in tightened chuck a minute or two to set adhesives before edging

Even tho it may sound like a lot of tape, what I really like is that when the lens is finished I just tear off the tape and no longer have to clean StickyStuff off the lenses. :)

PSI has a new blocking pad designed specifically for super hydophobic and oleophobic lenses call Oleo-Gold. It is brand new. If you would like to try some samples, email me at kgillen@looktopsi.com and I will send some out to you.

Holy zombie thread, Batman!

I have converted 100% to Big Red pads from Dynamic Labs. I've never had a single slip.
