Quality Control Reports

Sample QC Reports (Other than UL Listing)

Contego is perhaps the only intumescent manufacturer that uses dual redundant QC analysis of our entire production. We use UL, Materials Analytical Services and MAGI to critically evaluate our product on an ongoing basis using spectroflouroscopic analysis. Note how each graph over the past nine years is essentially identical.  Click on the links below to view each Sample QC report.
