To design higher performance surface coatings, coating formulators must choose from myriad polymer chemistries. The polymer holds the coating cohesively (internally) together and adhesively (externally) to the substrate to which it is applied. Proper polymer selection can be the most important factor in determining the physical and chemical properties, as well as protective capabilities, of the coating.
In addition to desirable qualities, each polymer typically has shortcomings. Polymer manufacturers have developed hybrid polymer technology to combine the advantages of one polymer species with another--while offsetting their shortcomings--in a synergistic manner ...
