Evaluation of Film from Calliburn Industries
Background: There is interest in the corrosion protection offered by film from Calliburn Industries.
Purpose: Evaluate corrosion protection offered by Calliburn film.
Method: FT-IR Spectroscopy
Razor Blade Test
SO2 Test
VIA Test
Tensile Test
Materials: Paragon 1000 FT-IR, Perkin Elmer
Razor Blade Test Kit
SO2 Test Kit
VIA Test Kit
Calliburn film (blue in color, 4.0 mil)
Cortec VpCI™-126 film
Universal testing system, Instron 4443
Procedure: The above tests were performed according to standard procedures for each.
Results:
FT-IR Spectroscopy: Spectrum contains peaks corresponding to carboxylic acid derivatives (most likely sodium benzoate) and a possible triazole based compound.

VIA Grades (Grade 2 or 3 are passing):
Grade 0- No corrosion inhibiting effect
Grade 1- Minute corrosion inhibiting effect
Grade 2- Medium corrosion inhibiting effect
Grade 3- Good corrosion inhibiting effect
SO2 Grades (Grade 3 and 4 are passing):
Grade 0- Extensive corrosion covering 25% or more of panel surface
Grade 1- Moderate corrosion covering 10-25% of panel surface
Grade 2- Slight corrosion covering 5-10% of panel surface
Grade 3- Very slight corrosion covering 0-5% of panel surface
Grade 4- No visible corrosion on panel surface
