What are the unique aspects and benefits of RST?
RST can be applied to continuous processing lines (e.g. reel-to-reel) or batch processing (e.g. nanoparticles). The RST process is extremely cost effective (low capital, energy, and operating costs) and uses environmentally friendly chemistries that are commercially available from many industrial suppliers. The RST process creates much more durable grafts than conventional silane polymer grafting techniques and can be applied a nearly limitless number of materials. Alexium’s process allows for durable grafting of multiple functions in a single process step. RST is not a “line of sight” process.
Why is RST an environmentally “green” alternative?
In addition to the enhanced material performance, the RST is based on an environmentally friendly process. By using microwave heating opposed to conventional heating, RST is notably energy efficient. Additionally, the chemistry used for this process employs “green” solvents and reagents, meaning that they are generally produced from renewable resources and that the chemicals are not hazardous to the environment. Further, the by-products of RST are not hazardous to the environment. All of this works to provide an additional driving force for customers to adopt Alexium’s technology to replace antiquated equipment. The RST process can significantly lower the overall CO2 footprint and waste emissions.
How does RST compare to plasma and other competitive technologies?
Alexium’s process is applied under atmospheric conditions using industrially available processing equipment. While the chemistry and microwave processing techniques are not trivial, the process is robust, and the capital and operating costs are very low when compared to other application methods. Because of the greater penetration depth of microwaves, exterior as well as embedded surfaces can be treated, meaning that RST is not limited to line-of-sight applications. Alexium’s process can apply multiple functional groups in one processing step and durably graft organic and inorganic compounds to a wide range of substrate materials.
How is RST scaled-up to meet higher production capacities?
The microwave graft occurs with just seconds of exposure and reel-to-reel applicators and batch reactors can be easily scaled to high volume capacity. For most applications, Alexium can insert an RST processing module into existing production lines. The processing equipment footprint is relatively small and can easily be integrated into most production lines.
How does Alexium engage with customers and/or interested parties?
Alexium provides customers with a turn-key solution in a variety of ways. Typically, Alexium will discuss with clients and partners the business opportunity and technical feasibility. If needed, Alexium will sign non-disclosure agreements, and develop a formal technical and commercial development plan. While Alexium has the capability to treat samples for initial demonstration, the end goal is typically to deliver customized processing capabilities and training to process material on-site. Alexium will formalize the business relationship through a license agreement or joint venture agreement.
