Waterborne Coatings

This article provides a brief overview of patents, trade secrets, and an in-depth discussion of infrequently used procedural options available at the United States Patent and Trademark Office (USPTO) that can be leveraged to gather critical information and thereby enable a decision maker to confidently elect to either apply for a patent or maintain a trade secret.

The object of this study was to evaluate the effectiveness of different modifications on anti-corrosive performance. Straight PUDs were used to prepare DTM coatings with only small amounts of additives and without the assistance of corrosion inhibitors, passivation fillers or pig-ments.

It was found that samples having a higher percentage of CNSL showed excellent corrosion scratch properties, and successfully passed the humidity and blistering tests. Analyzing the overall performance of the films derived from each sample, it may be said that all the samples showed good mechanical, chemical and corrosion resis¬tance, keeping cost in mind.

Due to their tailored system compatibility, the new sili¬cone surfactants are suitable for use in both aqueous one-component systems as well as in aqueous two-com¬ponent polyurethane and radiation-curable systems.

In this study, polyurethane-acrylic resins with UV functionality have been evaluated according to industry specifications for both interior and exterior industrial wood applications.

A new dispersion provides 1K, low-VOC wood floor coatings with the properties of a 2K floor coating.

A variety of factors that influence hot tire pick-up were examined to give more reliable and consistent results in laboratory HTP testing.

Despite the challenges of reformulating a coating from solvent‐based to waterborne and curing a low-molecularweight EPDM at ambient temperature, formulations have been successfully developed utilizing peroxide, oxidative and UV-curing systems.

New waterborne epoxy resins and amine curing agents offer traditional epoxy performance while meeting the market’s desire for higher performance, lower cost and lower solvent content.

Newer polymeric dispersants, which represent improved alternatives to the more traditional anionic dispersants, enable formulators to achieve good stability and color properties for dispersed pigments in waterborne paint systems.
