Title	Part 21 - Batch of Carbozinc 11 Sg Is Noncompliant in Cure Issues
Event Description	Carboline Company is notifying certain companies that a potential safety related noncompliance deviation in a basic component as defined in 10 CFR Part 21. The noncompliance involves a batch of Carbozine 11 SG Base that is not curing properly. It forms a poor quality film. A customer notified Carboline of concerns regarding the cure of a particular batch of Carbozine 11 SG. Technical Service originally felt it was application related and worked with the customer. An internal report was opened once cure issues remained after working with their technical department. An analysis of the batch by our plant Quality Control was requested; the results did not confirm the problem. Material was then sent into Saint Louis R&D for additional analysis. On Tuesday, October 8, 2008 the analytical evaluation was reviewed by the product chemist and the batch cure issues were confirmed. The batch was placed on hold and reports have been run to determine where the batch has been shipped. Carboline is requesting that the affected companies review their stock of Carbozine 11 SG and return any material with the batch number of 8G9892L. Further work is being done to determine the cause of cure issues with this batch of Carbozine 11 SG. At this time, Carboline has confirmed that this material is not curing properly and forms a poor quality film.
