How to make a rubbery edge coat like factories?

[magdy]

Dear All, 

I want to know which material and machine do factories use to seal and coat the leather edges with a thick rubbery coat? I don't think it is Giardini, or Fiebings or Stahl or United or any of these edge coats, because I compared those to the rubbery edge coat I have on many bags and they are not the same.......I also don't think in mass production of bags they will waste time applying 3 or 4 layers of these edge coats..... I think it is a synthetic material... It could be the one in the attached photo but I don't know what is it? BTW this material is damn good and sustainable. 

 

Can anyone help me please.
