: Identifies the specific coating (e.g., Jotamastic 80 ) and whether it is the base (Comp A) or hardener (Comp B).
Imagine a single tank lining fails after 18 months. Without the batch certificate, you cannot prove that the 50 drums you used all came from the same production run. With the certificate, Jotun’s quality lab can go back to the retention sample of that specific batch to determine if the failure was a manufacturing defect (Jotun’s liability) or an application error (your liability).
With the batch certificate, the yard could have proven the paint was NSF-certified for potable water. Without it, they had no defense.
If the product is older (5+ years) or the QR code is damaged, contact the Jotun subsidiary where the paint was purchased. Provide the batch number and the original order number. Note: Jotun typically retains batch samples for 7 to 10 years, depending on the product line. For very old batches (pre-2000), certificates may be archived on microfilm.
In industries such as oil and gas, marine, and construction, these certificates are mandatory for ensuring project safety, regulatory compliance, and long-term asset protection. Core Components of a Jotun Batch Certificate
A Batch Certificate, therefore, is an official document issued by the manufacturer that certifies a specific batch of product conforms to the technical specifications and quality standards claimed for that product. It acts as a "birth certificate" for the paint.
Crucially, each certificate is unique to a single batch number. Mixing two different batch numbers on a project requires separate certificates for traceability.
