Waterborne Coatings

To design an emulsion polymer with improved and balanced performance in the interior paint segment, Arkema has identified both polymer and formulation drivers to improve three performance targets

By incorporating a specialty amine-functional silane oligomer into existing waterborne silane pretreatments, the need for an elevated curing temperature is effectively eliminated, opening the door to this type of environmentally friendly technology to industries and markets that were previously restricted by this elevated-temperature curing requirement.

The new water-based additives and stabilization packages are designed to combine the efficiency of conventional products with the benefits of water miscibility and low to zero volatile organic compound (VOC) generation, as well as easy dosing and handling.

The low-VOC coatings market is projected to grow at a CAGR of 6.0% by 2024. Water¬borne, powder and radiation cure technologies are the major low-VOC coating technologies, and are thus gaining in popularity.

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.
