Paint and Coatings Additives

RSS

Inhibispheres are a new class of corrosion inhibitors for powder coatings. Inhibispheres utilize a sustained release technology based on corrosion inhibitor microencapsulation via a silica matrix.

By definition, additives are added in small quantities, often less than one point percent, to re-inforce selected chemical or physical properties of the finished paint. The powder coatings sector is no exception, and has some limitations that are intrinsic to the technology itself, which are linked to the physical state of the paint before application on the piece to be painted.

This work demonstrated that using NCMPO emulsions can allow formulators to bond to low-surface-energy substrates and high-surface-energy substrates.

PCI recently spoke with Steve Ridge, Senior VP Supply Chain and Manufacturing at Elementis, to get his views on the company's experiences, challenges and successes during the COVID-19 pandemic, as well as their outlook for the market and business strategies moving forward.

Graphite Innovation and Technologies Inc. has developed an environmentally friendly, hard foul-release coating that can be easily cleaned and does not require the application of primer underlayers.

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.

Self-healing additives can be used to improve the performance of a coating system that is subject to mechanical damage, micro-cracking and subsequent corrosion of the substrate while in service.

To obtain continual improvements in scratch- and abrasion-resistant coatings, a variety of additive technologies have been developed to address this issue. In this study, the article examines additive technologies ranging from surface-active siloxanes and nanocomposite technology to synthetic amorphous silica and co-binders.

The goal of this study was to understand how the properties of process oils (15 naphthenic and one paraffinic) influence the coating properties of a two-component aromatic urethane system.

Using the right defoamer will lead to many desired effects in the final coating performance. First and foremost, the foam will be eliminated and the appearance will be at its best. There are also additional benefits.
