TAILIEUCHUNG - Study on anticorrosion properties of epoxy primers on steel

Epoxy resin DER 671X75 was reinforced by nanoclay cloisite 30B with content of 2% and primer coatings based on epoxy resin DER 671X75 were formed with pigments, fillers. Epoxy coating films were exposed by electrochemical method in NaCl % solution in 28 days and salt spray accelerated tester in 330 hrs. The results show that nanoclay cloisite 30B are improved anticorrosion properties of primer coatings based on epoxy resin DER671X75. | Vietnam Journal of Chemistry, International Edition, 54(4): 419-423, 2016 DOI: Study on anticorrosion properties of epoxy primers on steel Huynh Le Huy Cuong1, Tran Vinh Dieu2*, Nguyen Dac Thanh3, Doan Thi Yen Oanh4 1 Faculty of Chemical Engineering, Ho Chi Minh City University of Food Industry 2 Polymer Research Center, Hanoi University of Science and Technology 3 Polymer Research Center, Ho Chi Minh City University of Technology 4 Publishing House for Science and Technology, Vietnam Academy of Science and Technology Received 1 June 2016; Accepted for publication 12 August 2016 Abstract Epoxy resin DER 671X75 was reinforced by nanoclay cloisite 30B with content of 2% and primer coatings based on epoxy resin DER 671X75 were formed with pigments, fillers.

Epoxy primer coating, nanoclay cloisite 30B, epoxy resin DER 671X75, electrochemical, anticorrosion properties steel. 1. INTRODUCTION Corrosion of steel structure caused calamitous consequences to the economy. To protect steel from corrosion, coating systems based on epoxy, polyurethane and polyurea binders have been used. Polyurea resins possess excellent properties such as mechanical durability, anticorrosion and weather resistances [1-3]. Recently, special additives as nanosilica and nanoclay were studied to improve physical and mechanical properties of composites and coating [4-7]. Studies on primer coating based on epoxy resin DER 671X75 with pigment/fillers and nanoclay cloisite 30B have not seen on publication. This paper has shown the effects of nanoclay cloisite 30B to mechanical properties and anticorrosion properties of primer coatings based on epoxy resin DER 671X75. 2. .
