PENGGUNAAN SISTEM LAPIS LINDUNG JENIS POLYURETAN UNTUK APLIKASI DI DAERAH MARITIM[Using Polyurethane Type for Coating System at Maritim Environment]

Effect Analysis on Coating Methods and Corrosive Media Variations toward Adhesion Strength, Corrosion Rate, and Metallography of ASTM A36 Steel with Polyurethane Coating

“…Corrosion is defined as a decrease in the quality of metals due to the electrochemical reaction with their environment [1]. Corrosion can make the metal structures thinner, perforated, and eventually cause cracks which then cause sudden structural failure [2]. From economic perspective, corrosion is one of the main problems in the oil and gas industry because it cost a lot of money to deal with [3].…”

“…The use of polyurethane as a protective material by Sholeh and Rohani [13] concluded that polyurethane has abrasion resistant, high flexibility, and resistance to wear properties. Research by Nasoetion [2] concluded that the use of polyurethane was not strong enough to handle bending loads but was good enough in blistering, cracking, and rusting testing. Other research conducted by Samimi [3] concluded that polyurethane material has high adhesion strength, suitable flexibility, good chemical and high temperature resistance, and good friction resistance for pipelines.…”
