Abstract
Carbon steel is a material that has a main composition of iron, making it susceptible to corrosion when exposed to the environment. The reactive nature of iron makes the steel structure quickly degrade, especially when dealing with corrosive environments that have high levels of NaCl in the air such as in offshore areas or in coastal areas. To anticipate the degradation that occurs in steel, prevention is generally carried out by coating the steel with a polymer layer that functions as a barrier so that the steel does not experience direct contact with the environment. This study aims to qualitatively analyze the Pull-off test of epoxy coating system based on the dolly face characteristics which shows that the surface preparation avoids the failure of the primary coating. Proving that Pulloff test of epoxy coating system based on dolly face characteristics shows that curing time reduces the failure rate between layers, quantitative performance of Pull-off test of epoxy coating system based on pull-off strength value of samples with prepared and unprepared surfaces is directly proportional to curing time of primary layer, and proving Degree of Cure of epoxy coating system based on quantitative analysis of crosslinking amine groups is directly proportional to curing time of primary layer.--
Baja karbon merupakan material yang memiliki komposisi utama berupa besi, sehingga rentan terhadap korosi ketika terpapar dengan lingkungan. Sifat besi yang reaktif menjadikan struktur baja dapat terdegradasi dengan cepat terutama bila berhadapan dengan lingkungan korosif yang memiliki kadar NaCl tinggi pada udara seperti di area lepas pantai atau di daerah pesisir. Untuk mengantisipasi degradasi yang terjadi pada baja, umumnya pencegahan dilakukan dengan melapisi baja dengan lapisan polimer yang berfungsi sebagai penghalang agar baja tidak memiliki kontak langsung dengan lingkungan. Penelitian ini bertujuan untuk menganalisa kualitatif Pull-off test sistem coating epoksi berdasarkan karakteristik dolly face menunjukkan bahwa preparasi permukaan menghindarkan kegagalan pada lapisan primer. Membuktikan bahwa Pull-off test sistem coating epoksi berdasarkan karakteristik dolly face menunjukkan bahwa waktu curing mengurangi tingkat kegagalan antar lapisan, performa kuantitatif Pull-off test sistem coating epoksi berdasarkan nilai pull-off strength sampel dengan permukaan prepared dan unprepared berbanding lurus dengan waktu curing lapisan primer serta membuktikan Degree of Cure sistem coating epoksi berdasarkan analisa kuantitatif gugus amina crosslinking berbanding lurus dengan waktu curing lapisan primer.
