Binders that show a high contact angle both before and after the salt spray test perform better for corrosion protection, compared to those that show low contact angles before and after the test.
This study has shown that DMMOPA has a unique combination of balanced physical properties. These physical properties offered DMMOPA-neutralized paints a multitude of performance advantages in a variety of waterborne paint systems as discussed in this article, such as enhanced hardness and solvent resistance in polyol-MF baking coatings, as well as better gloss, scrub resistance, water resistance and corrosion resistance in latex paints.
Functional coatings are an exciting and viable means to remove indoor air contaminants due to the significant surface area that walls, ceilings, doors and floors provide as a "vehicle" to degrade VOCs.
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.
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.
International hard coatings specialist Hardide Coatings, which has a production facility in Virginia, USA, has hailed a successful holiday season after solving a wear issue that was slowing the processing of letters throughout the United Kingdom.
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.
The Lunda/Ames Joint Venture, a major partner in the multiyear construction of the St. Croix Crossing, chose to extensively apply an easy-to-use, low-toxicity corrosion inhibitor to protect various post-tension strands placed throughout the bridge during construction.
After 15 years of development and countless hours of collaboration across a number of experts, this group of researchers was finally able to crack the code on structural color to develop "omnidirectional" structural color that does not change when viewed from different angles.
