High temperature performance of phenolic novolac epoxies - thermal degradation and barrier properties

Phenolic/ novolac epoxy coatings are being used as protective barriers for assets operating at elevated temperatures, typically up to 204 °C (400 °F), and there is a large variety of coating products which all fall under the generic description phenolic/ novolac epoxy in the market today. This study has resulted in deeper knowledge about the phenolic/ novolac epoxy coatings and their high temperature service properties and illustrates the importance of testing at various temperatures for a long duration.

Selecting heat-resistant coatings: beyond NORSOK standards

In the seventh edition of NORSOK M-501 standard (Nov 2022), new coating system specifications were added for high temperature service – systems 1D, 6C, 10A, and 10B. The study highlights that selecting a heat-resistant coating should not depend only on standard approvals like NORSOK but also on factors like surface tolerance, application conditions, and in-service requirements.

Challenges and insights behind qualifying a protective coating as a CUI preventive coating

Over the last years an extensive amount of testing has been performed to test and qualify coating systems for CUI protection. In a conference paper published by Association for Materials Protection and Performance (AMPP) and authored by Jotun R&D experts, a variety of test results are presented to show how complex it is to qualify coatings to prevent CUI occurring.
