Material coatings are additional layers that provide extra functionality or improve the strength of the substrate. PSI has developed coatings for improving the lifetime of energetic materials, increasing the stability of hydrogen storage systems, and adding anti-microbial properties to medical contact surfaces. Functional coatings are key elements of a broad range of materials systems including obscurants and chaff, batteries, separation membranes, medical textiles, corrosion inhibition and high temperature protection. We have provided coatings to a range of defense, energy and aerospace organizations.
A great example of this is PSI’s quaternary ammonium cation (QAC) technology, which provides high anti-microbial efficacy against a broad range of gram positive and gram-negative bacteria, as well as fungi. Fabrics treated with the unique dendrimer chemistry are highly biocompatible and meet or exceed the performance of silver-based treatments for first cycle use and exceed their performance after laundering. The long-lasting antimicrobial efficacy has been proven for multiple textiles, including combat stretchers and clothing.
PSI is working on coating high performance ingredients that are of interest to the DoD. Many of these ingredients are highly hygroscopic and suffer from incompatibility issues with other formulation components. PSI has developed coatings for improving the lifetime of energetic materials, increasing the stability of hydrogen storage systems, improve formulation mixing, improve overall formulation performance and reducing the sensitivity of energetic materials.
