Mechanicals Improvement Provides a combination of reinforcement and impact resistance without sacrificing ductility and elongation
• 400% increase in impact resistance @ 2.0% loading in epoxy
• Prevents cracking in latex paint Controlled Release Protection Unique hollow tubular morphology enables the loading and controlled-‐release of active agents to provide protection against microbial growth and corrosion Adhesion Improvement Proven to enhance the adhesion force by a factor as much as 8x on a wide range of substrates Hard Anti-‐Scratch Coating Proven in polyurethane coatings to improve the hardness of the coating leading to anti-‐scratch performance UV Curing Performs as an optical fiber to provide a pathway to help conduct light throughout for an expedited, complete, and even cure

Ammoniated product grade with low reactivity and pH neutral. Ideal for applications where acidity has the ability to negatively affect the polymer network.
-‐HP:A
-‐XR Untreated product grade with slightly lower reactivity and acidity (pH 5-‐7) due to 2.0% iron oxide content.

Controlled Release Dragonite’s unique hollow tubular morphology enables the loading and controlled-‐release of a range of active agents uniformly and in appropriate dosages to protect against mircrobial growth and corrosion Release rates can be engineered through the selection of tube geometry, encapsulation, and tube-‐ending stopper complexes
Anti-‐Corrosive Coatings Dragonite loaded with anticorrosive agents can be added to coatings to provide long efficacy corrosion resistance. Figure A. Oil-‐based paint untreated Figure B. Oil-‐based paint treated with Dragonite loaded with ammonium molybdate
Functional Filler Dragonite delivers value to coatings as a functional filler by virtue of its high brightness, purity, and tubular structure Advantages as a Functional Filler:
• Improved mechanicals • Resistance to weathering and rapid deformation • Extender: opacity and rheology • Suspending and thickening agent
