- Biocompatible, non-toxic, and recognized by the FDA as GRAS
- Tunable release rates
- Increased efficacy times
- Shelters active agent from external degradative environment until it is released
- Simultaneously performs as a functional filler
Dragonite™ performs as a drop-in additive in paints and coatings to create an unrivaled sustained-release protection against microbial growth and corrosion. Utilizing its inner lumen as a natural reservoir, Dragonite can load, store, and control-release a range of biocides uniformly and in appropriate dosages. The product disperses easily in a wide range of carrier materials and can release single or multiple agents at predetermined rates. Serving a dual-purpose, the addition of Dragonite also simultanously provides the benefits of a functional filler, dramatically improving mechanical properties.
In addition, Dragonite acts within UV curable systems as an optical fiber to conduct light into the coating to insure proper cure throughout the material depth.

Release rates can be engineered through the selection of tube geometry, encapsulation, and tube-ending stopper complexes. A self-healing effect can also be achieved by embedding Dragonite into a polymer matrix such as a sol-gel coating - releasing the agent only when triggered.
The addition of Dragonite also delivers considerable value to paint products as a functional filler by virtue of its high brightness, low levels of titania, and tubular structure.
Advantages of Dragonite as a filler in paint:
- Improved tensile strength
- Resistance to weathering and rapid deformation
- Extender: opacity and rheology
- Suspending and thickening agent
Dragonite - Paint Tensile Properties
Dragonite™ provides a UV transparent optical fiber which, when added to a pigmented coating, provides a pathway to help conduct light throughout for an expedited, complete, and even cure. In addition, Dragonite™ also boosts a coating's adhesion due to its unique ability to trap coating impurities, a typical cause of weak boundary layers.
- Accelerated cure throughout the coating
- Reinforcement of mechanical properties
- Improved adhesion in systems susceptible to contaminants
- Better scratch and scuff resistance
