COA Certificate of Analysis
Certificate of analysis or COA
COA are the final testing numbers for every batch of pigment manufactured. It is important the COA match the standard on the Spec Sheet used by the manufacturer.
We track batches on all pigments with the exception of samples. We hold examples of C of A for all our pigments and these may be distributed as needed as examples. Generally, we request a batch related C of A for retail manufacturers who generally order a minimum of 10 kilos. Please request one at the time of ordering 10 kilos or more.
