Do synthetics really "bond" to paint?

No specific data but it would seem that the monomers of a acrylic create a "ionic" bond (strong) whereas the resin creates a covalent (electron sharing - weaker) type.

covalent bonds are stronger than ionic bonds.

In context to protectant bonding: Yes there are some covalent bonds that contain enough electronegativity sharing to be stronger than some ionics.



But in general. unlike ionic compounds, covalent molecules exist as true individual molecules. Because electrons are shared in covalent molecules, no full ionic charges are formed. Thus covalent molecules are not strongly attracted to one another. As a result, covalent molecules move about freely and tend to exist as liquids or gases at room temperature.



Ionic compounds tend to form crystalline solids with high melting temperatures.

In fact some of the strongest bonds are between elements that have the same electronegativity, e.g the C triple bond and N triple bond. It is due to electron orbital overlap, not electronegitivity

It is easier for ionic molecules to have long range bonding networks, but as you know, covalent bonds can do that too, e.g. the backbone of polymers and diamond are covalent bonds.

...many of which also dissolve when you put it in water.
 
I concede that if we get into the atomic realm your statement is true. But as I stated or prefixed my post:



In context to "protectant bonding"



This discussion is "intramolecular" and devoid of adequate data. :bow
 
Intel, that's the million dollar question and beyond data available (DK :nixweiss). Without the branching point (crosslinking point of monomer) info it is impossible to guess.



Polymer is such a generic term.



Technically sucrose (table sugar) is a polymer of 3 glucose moleculars (Monomers).



What type of monmer are we dealing with in polymeric sealants?



It would nice to know this info. It would make usage of different products and their reactions to toppers, QD's, surface prep, intra-company product mixing, etc a whole lot more intellectually driven and less trial by error and old wives tells.



But than where would the fun of experiment go..... Down ;)

I agree with you 120%

This is whay I was wondering, really.
