Assessment of surface protection can be carried out by use of slip tables and AGR hot-end coating technology.
The longevity of the coating performance can be assessed using our AGR line simulator, whereby bottle to bottle abrasion damage is induced at the contact points, as may be expected on a filling line; the strength of the virgin and abraded samples can then be compared. This is of particular use for returnable glassware.
Hot end coatings and finish coatings can be measured to determine thickness in CTU’s and observations can be made on visual appearance if required. Cold end coatings are assessed using a slip table, to determine the lubricity of the coating.
