Co-polymerized acid functional monomers, such as acrylic acid and methacrylic acid, provide electrostatic stabilization to waterborne latex polymers when they are neutralized, and they offer sites for various cross-linking reactions. Amine functional monomers...

...). Most common polymers have carbon (organic material) backbones, though polymers with inorganic backbones (e.g., silicates and silicones) are possible. Polymeric materials exhibit strong covalent bonds within each chain; however, individual chains are frequently linked via secondary bonds (i.e., van der...

There is a relatively large number of epoxy coating systems, because there are a number of epoxy resins of different molecular weights and compositions, as well as a number of cross-linking agents that co-polymerize with those epoxy resins. Each is discussed in some detail, although materials suppliers always...
