Process energy coat comparison

A nonchromated, water-borne primer applied to [2B] alloy samples, with the appropriate surface preparation and plasma deposition of an ultrathin plasma polymer, was also compared to controls prepared by depositing a chromated primer on chromate conversion-coated A1 substrate. The same comparison was also performed for IVD Al-coated 2024-T6 substrates (pure aluminum is deposited by ion vapor deposition process on aluminum alloy 2024-T6). In the latter case, the primer could not be removed from the IVD Al-coated panels that were treated with the plasma polymer prior to spray primer application. It is interpreted that the water-borne spray paint penetrates into the column structure of the top surface of the IVD Al-coated substrates when the surface energy was modified by the application of a plasma polymer. This effect could be viewed as interactive coating with a porous surface. 

The development of photoinitiators for cationic polymerization is an important one, with both practical and fundamental applications. Practical uses are primarily in the area of light-induced curing of coatings, a process which is expected to be energy-conservative in comparison with conventional thermal curing (4). 

For inorganic coatings, thermoanalytical techniques can similarly be used to measure purity of raw materials including verification of the origin of some minerals, evaluation of thermal stability, estimation of the heats of reaction, determination of the nature of the reaction, establishment of processing temperatures, comparison of adhesion energies, and, by phase diagram determination, selection of a composition for the final...
