Evaluation of Tyco Stretch Film for Corrosion Inhibitor Protection

9001ds iso-14001

Background: James Gaynor/Buff-Pac has interest in the corrosion inhibitor protection offered by Tyco stretch film.

Purpose: Evaluate the contact and barrier corrosion inhibitor protection offered by Tyco stretch film.

Method: SO2 Test

Razor Blade Test

FT-IR Spectroscopy

Sodium Nitrite Test

Materials: SO2 Test Kit

Razor Blade Test Kit

Paragon 1000 FT-IR, Perkin Elmer

EM Quant Sodium Nitrate/Nitrite Test Kit (Lot/Exp, OC191325/Feb 04)

Procedure: The above methods were performed according to standard procedures for each.

FT-IR Spectroscopy: salt of carboxylic acid was detected

Sodium Nitrite Test: The Tyco film does not contain Sodium Nitrite.

Conclusion: The Tyco stretch film offers limited barrier corrosion protection and no contact corrosion protection.

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
