Results from INVESIL Antimicrobial Surface

Staphylococcus aureus is a Gram-positive, round-shaped bacterium. Pseudomonas aeruginosa is a common Gram-negative, rod-shaped bacterium. Third-party testing suggested 99.99% protection against pathogens through our INVESIL surface.

Conductivity Measurement

Conductivity Testing of FLYCO Surfaces

Conductivity testing was done as per ASTM E1004 over coated aluminum 2024 panels. No change in conductivity was observed on the coated and uncoated portions. This suggested that FLYCO does not affect the conductivity of the metal surface.

Thermal Analysis

Thermal Analysis of FLYCO Surfaces

The thermogravimetric analysis was conducted in an inert atmosphere on a solid FLYCO surface. A thigh thermal stability was found in the material with exceptionally large residual content.

Electrochemical Tests

Electrochemical Corrosion Testing on FLYCO Surfaces

The electrochemical polarization (anodic and cathodic) and impedance testing in 3.15% NaCl at ambient (20°C) temperature. The 2×2 inch aluminum -2024 panels were coated and compared with uncoated panels. The presence of the surface has significantly reduced the current density throughout the test potential range of ±600 mV of the open circuit. The data indicate that the surface acts as a barrier to slow the diffusion of reactants to the metal surface. In general, surfaces are considered protective when their low frequency (≤0.1 Hz) impedance values are equal to or greater than 1 x E6^2, higher values indicating better protection. The coated samples in the electrochemical impedance analysis test exhibited impedance values as high as 1 xE9^2. These tests indicate that the protective property of the surface is significant.

Corrosion Testing

Corrosion Testing on FLYCO Coated Metals

The uncoated and coated aluminum panels were tested in an accelerated corrosion test chamber as per ASTM B117 and GM 9540P standards for 6 weeks (i.e., 1008 h). The FLYCO-coated aluminum panels did not show any sign of corrosion until 336 h. A little surface roughness was observed on coated aluminum after 1008 h. Surface effectively protected aluminum alloys.

Atomic Force Microscopic Image of AVIRAL Surface

A polished silicon wafer was coated with AVIRAL surface and dried in ambient conditions. The coated surface was scanned with Atomic Force Microscopy in tapping mode. A significantly smooth surface with surface roughness in the sub-nanometer regime was observed under the microscope. This demonstrates that AVIRAL could deeply penetrate and bind with individual grains of the substrate. NAVY Report- AVIRAL Anti-icing coating

NAVY Report on Anti-icing AVIRAL Surface

Two Aviral products were provided to NAWCWD, USA, and testing was performed IAW “General Task Description WD CSA 20-XXXX-XXXX” dated November 19th, 2019. The Aviral and control samples were sprayed onto 5052 aluminum test panels and allowed to cure. Ice adhesion testing was then performed on the samples; both Aviral 2012 and Aviral 2014 displayed an ice adhesion strength of less than 1 psi. AVIRAL product displayed significantly low ice adhesion capabilities (13x – 16x) compared to other commercial products and more than 80x compared to an uncoated metal surface
