摘要：

Recently polyurea (PU) is widely used as a surface coating to protect the material under various harsh loads, hazardous chemical reactions and climatic conditions. The high efficient isocyanate-amine reaction kinetics makes it mandatory to use a reactive spray coating technique for the realistic production of PU. However, the efficiency of the PU depends on various process parameters of the plural spray coating system. Herein, the effect of plural spray coating process parameters, namely, mixing ratio, temperature, coating pressure, and stand-off distance was studied by comparing mechanical properties such as hardness, tensile, elongation, young’s modulus, tear and wear index of PU. Besides, the optimal process parameters and corresponding levels have been identified using the Taguchi method and it has been found that each property has a different best process parameter. To circumvent this, grey relational analysis (GRA) was carried out and it has improved overall efficiency by 7.71%. © 2020 Informa UK Limited, trading as Taylor & Francis Group.
