Abstract

Fusion Bonded Epoxy (FBE) merupakan pelapis berbasis epoksi yang banyak digunakan sebagai perlindungan korosi pada pipa baja di berbagai sektor industri. Kualitas adhesi FBE sangat dipengaruhi oleh parameter aplikasi, khususnya suhu pemanasan permukaan sebelum pelapisan. Penelitian ini bertujuan untuk menganalisis pengaruh diferensiasi suhu pemanasan permukaan terhadap kekuatan adhesi lapisan FBE, dengan variasi suhu 170°C, 210°C, dan 260°C serta ketebalan pelapis 300–500 μm. Metode pengujian yang digunakan meliputi visual test, thickness test, holiday test, pull-off test, Differential Scanning Calorimetry (DSC), dan Cathodic Disbondment (CD) test. Hasil penelitian menunjukkan bahwa suhu aplikasi berpengaruh signifikan terhadap kekuatan adhesi dan stabilitas termal lapisan. Suhu 210°C menghasilkan nilai adhesi, kestabilan termal, dan ketahanan pada kondisi katodik yang lebih baik dibandingkan suhu lainnya. Temuan ini diharapkan dapat menjadi dasar dalam optimasi parameter aplikasi FBE, serta meningkatkan keandalan sistem pelapisan pada kondisi operasional ekstrem.

Fusion Bonded Epoxy (FBE) is an epoxy-based coating widely used for corrosion protection of steel pipelines across various industrial sectors. The adhesion quality of FBE is highly influenced by application parameters, particularly the surface preheating temperature prior to coating. This study aims to analyze the effect of thermal differentiation in surface heating on the adhesion strength of FBE coatings, using temperature variations of 170°C, 210°C, and 260°C with a coating thickness of 300–500 μm. The tests conducted include visual inspection, thickness measurement, holiday test, pull-off test, Differential Scanning Calorimetry (DSC), and Cathodic Disbondment (CD) test. The results show that the application temperature significantly affects the adhesion strength and thermal stability of the coating. A temperature of 210°C produced the best performance in terms of adhesion strength, thermal stability, and resistance under cathodic conditions. These findings are expected to serve as a reference for optimizing FBE application parameters and enhancing the reliability of coating systems under extreme operational environments.
