QuantiShield -Coating POLYAMIDE  EPOXY PRIMER PLUS VAPOR PHASE CORROSION INHIBITOR (VCI)

 

QuantiShield VCI  introduces a new two-part polyamide epoxy primer coating having superior corrosion prevention properties  by virtue of a high-performance vapor phase migratory corrosion inhibitor  (VCI). The primer conforms to Military Specifications (MIL-DTL-24441) in all formulas and types as modified by the addition of the VCI agent to Part A in an amount that when Parts A and B are combined and applied the resulting dry film contains 2.5 Wt.,% of the VCI agent.

 

Performance properties are measured with and without  the VCI agent added to the primer applied on black beauty abraded steel panels in the white metal and 24 hour salt fog exposed corroded conditions. The primer applied at a dry film thickness of 3 mils is exposed for 500 hours in a salt fog chamber in accordance with ASTM B117. Dry film adhesion before exposure is rated at 5B per ASTM D3359 on all samples of  coated  steel. Corrosion resistance is measure per  ASTM D1654 (Evaluation of  Painted Specimens Subject to Corrosive Environment) where a rating of 10 is zero degree of creep away from the X scored area and a rating of 1is 13 to 16 millimeters of creep,and ASTM D610 for the percentage of surface covered with rust spots where 10 is no rust and 1is 56 to 75 percent of surface rusted.

​

The following performance ratings are supplemented by the attached photographs.

The measured performance on rust-covered steel is due to  the ability  of the VCI agent to migrate through the rust layer and inhibit  further  corrosion of the white steel layer and also to migrate into recessed areas where contact corrosion inhibitors cannot reach.
