Have you ever made a fancy cocktail or a special cake from scratch? What is the first thing that you need when doing so? You need a recipe to know what ingredients are reguired,how to mix them and in what order,and how long it needs to chill or bake.Mixing paint for an industrial coatings project is no different.The recipe when mixing paint is typically found on the product data sheet(PDS)-and not just any PDS,but the most current one,since manufacturers are often updating PDSs to reflect formula changes or lessons learned.The good news is that it is easy to find the most current PDS online at the product manufacturer’s website or linked to an industry association or inspection app.When one sees a trailer full of paint on a jobsite,the PDSs and associated safety data sheets(SDSs)should be hanging nearby.We can learn the following from the PDS: 1.Generic type of the material and its in-tended uses;2.Shelf life and storage temperatures;3.Mix ratio and mixing instructions;4.Package size;5.Sweat-in(induction time)and pot life at various temperatures;6.Volume-solids and volatile organic com-pound(VOC)content;and 7.Acceptable thinners and percentages.Let’s look at these in more detail.
