Bond...James....how does it break? - Page 2

on mobile phone so forgive! Don't forget that if your system requires primer it does so for a reason and That's to create the attraction and thus the bond. Acid primers create hydrogen bonds acid free primers create covalent bonds. I wouldn't ditch the primer if your system requires it. Don't know if other systems using acid free primer would create a covalent bond direc with the nail plate if prep were perfect.

Good point Cathie!
As I only use CND products that is what I am referring to.
I feel I have been quite clear that I am only talking about Radical & Retention+ monomers and Acid Free primer.

Obviously users of other enhancements systems will need to check with their Educators....
unless of course an Educator from another company would post on this thread for all to see!
Don't be shy!!!

I understand it, that if you use the monomer with no primer, it will be stronger as you haven't introduced another link in the chain which can have a weakness and break down.

If you do use the primer, then although it will be ok, there is always a possibility of a break down later, so less bits added, less chance of breakdown, if i understand it right??

Hope so, or i have fried my brain....

this is what i was thinking...ish

The acid primer creates a kind of three way bond....imagine a sandwich, the primer being the filling, bottom slice is nail plate and top slice is product.

The primer creates a hydrogen bond with the nail plate, primer is needed to make the attraction and create the bond with the nail plate for monomers that require primer....a bit like if you do a cheese sandwich without butter, the cheese doesn't stick to the bread.

Then the other side of the primer (imagine primer not as a liquid but a solid...GMG uses the analagy of double sided sticky tape) creates a covalent bond with the product.

Now to be quite honest, I don't know what the heck type of a bond would be created with a system requiring primer where primer wasn't used....likely a zilch or very poor bond!

Does this make sense at all?

My mind has now taken this further, thanks to Izzi....maybe I am now truly obsessed.....

New question.......does the product break down before the bond does? For example, resins create a covalent (strongest) bond with the nail plate, but the single link polymers of the resin break down relatively quickly......so if product is breaking down....with the oldest product being closest to the nail plate, the bond is going to break down also, albeit before its time as the product has broken down first.
