This article was prepared in an effort to assist in this decision-making process and to help end users understand the newer technology and to know the common differences between the traditional three-layer coating system and the latest polyurethane coating technology.
Recently introduced industrial chiller systems incorporate a significant series of hardware, software, material usage and design improvements. The combination of improvements in each of these domains has led to a significant overall performance improvement for this type of equipment.
UV cationic coatings present a viable and attractive option to OEMs, sheet metal mills and formable sheet metal fabricators for precoated deep draw steels to present-day conventional sheet metal forming, bending, stamping and/or fabrication operations that require secondary conventional industrial conformal coatings processing, as well as an effective delivery transport mechanism for new pathogen inhibition and biocidal efficacy technologies.
The adhesion/corrosion balance of the previous study yielded significant new insights into resin design. Polymers with good wet adhesion and good corrosion resistance could be isolated, and those properties correlated back to their monomer compositions and particle morphologies.
Smart materials are becoming an important part of our future, and in many cases they are right under (or above) our noses today. Every-day examples range from your child’s forehead thermometer to your sunglass frames.
Semiconductor packaging assemblies require immense durability to protect the finished device from heat, physical impact, warping, static electricity and moisture. Therefore, formulators of epoxy compounds for semiconductor packaging assemblies require epoxy resins that deliver multiple performance characteristics that are dependent upon the requirements of the application or location of the finished device.
In the 1960s a coating system formed by overcoating a molten hot-melt coating with a latex paint was conceived as an answer to a search by the wood siding industry for a primer to improve paint performance on its product. Performance testing, including weather exposure, had a positive outcome, but circumstances prevented commercialization. Thirty years later, the originator of the concept undertook a more thorough investigation. This article is a public a report on coating system composition and performance.
The introduction of new substrate wetting additives improves the spreading capacity of emulsion paints. Also the effectiveness in filling the crevices/pores of concrete substrates is highlighted by the results of accelerated efflorescence or alkali block testing.
