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 thermogravimetirc analysis was conducted in inert atmosphere on 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 open circuit. The data indicates that the surface is acting as a barrier to slow the diffusion of reactants to the metal surface. In general, surface 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 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 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.

AFM Image

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. Significantly smooth surface with surface roughness in sub-nanometer regime was observed under the microscope. This demonstrate 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 product and more than 80x compared to uncoated metal surface
