The appearance a coating provides can sometimes be just as important as is protective properties. Ever-growing budget concerns have increased the demand for coatings that provide a longer lasting aesthetic finish. This paper will explain the basic terminology, testing procedures, analytical instruments and specification development for coating color, gloss, reflectivity and other appearance parameters. The appearance characteristics of various coatings will also be discussed.
When establishing the minimum conditions suitable for coating concrete, many coating manufacturers, and hence specifying engineers and contractors, generally rely on unrealistic moisture content and moisture vapor emission rate requirements. These compulsory values are founded on laboratory testing rather than field experience, or worse still, on supposition rooted in unachievable and unrelated requisites.
This paper will address both existing and new air barrier technology. Manufacturers, engineers, architects, trade professionals, and testing agencies will learn essential features of this emerging industry. Manufacturers will learn about the material properties and product performance requirements of air barrier coatings. Engineers and architects will learn basic building science principals required to create an air barrier utilizing coatings.
The mechanical properties of polymeric coatings are often overlooked because researchers are not aware of how modern instrumentation can now aid them in understanding how a particular product may survive in service conditions. In many applications the two main considerations are aesthetics and durability, both of which can be directly related to the mechanical properties of the base material.
