Hi! the main issue is coming from the etching/rinsing process. This is something I'm pretty familiar with...I may fix this all if you just consider using our lacquer which is identiacl to the one you...

Of course, you need to put clean lenses in the HC machine...which is not a cleaning process but an etching one...problem is that most of the machines on the market have poor rinsing capabilities,...

First of all, please check if these cracks are on both sides or only on one side, and in that case, which one...

Good old idea, but I have developed and patented my own solution which also could work with a microwave oven, but on working with a regular tinting equipment, this is what you may get when using...

Dear all,

I know my comment comes a bit late, but it's time to tell the truth to the optical community...
SCL started with this type of simple machines for labs in the early 90's when the only...

Yes Mr or Ms X! :wink:, the lacquer is the hardcoat that was mentioned. Newton rings are only a cosmetic issue as they are mostly visible under neon lights, i.e. in the shops. Customers who are not...

A lacquer is a liquid hard coating that can be applied by spin or dip coating and cured with a UV or thermal oven. Yes, there are no 1.74 lacquers available in the market, because the only ways to...

Hi Brandon,

I have worked with SDC in the past and I can tell you that I know that lacquer pretty well; everything you are describing I can testify. We made a new coating taht you may use as a...

Ciao Marco,

Yes I can testify that you are what you wrote. You know my previous experience (SDC, NGL, FISA), so I know this process from all possible ends and this is an issue I had to fix when I...

Hello everybody! I know that most of you are located on the others ide of the Atlantic Ocean, however it may be interesting to go to Paris (Sept 17-20) this year, as there is a new format for the...

Also called Ammonium Bifluoride, it is a salt from ammonia and hydrofluoric acid. If you use it at a 10% concentration (in a plastic container), you will remove your AR without damaging the HC. You...

If this is not too late to tell you that, bear in mind that Satis does not produce any lacquer. They resell SDC's lacquers under their own name. Since this HC process is rather complex and all...
