“…Kulit sintetis umumnya terdiri atas lapisan atas, lapisan tengah dan lapisan dasar serta kain penguat . Lapisan atas biasanya diformulasikan untuk menyerupai permukaan dari kulit asli (Sholeh and Rochani 2018). Sementara itu, lapisan pada kulit sintetis juga dapat dibuat lebih lembut dengan foam.…”

Kulit sintetis pada saat ini semakin banyak digunakan karena memiliki kelebihan proses yang lebih mudah dan biaya produksi rendah. Pembuatannya bahan ini secara umum melibatkan proses pelapisan dan pemanasan. Penelitian ini bertujuan untuk mengetahui pengaruh waktu pemanasan terhadap kesesuaian warna dan tebal kulit sintetis berbahan baku polivinil klorida. Kulit sintetis dibuat menggunakan bahan polimer PVC dengan penambahan aditif plasticizer DOP, filler kalsium karbonat, stabilizer, blowing agent azodicarbonamide dan pigmen. Pencampuran bahan menggunakan laboratory two roll mill pada suhu 160oC sedangkan pemanasan dilakukan pada oven drying dengan suhu 220oC. Ketebalan kulit sintetis divariasikan antara 0.5-2.4 mm dengan selisih tiap sampelnya 0.1 mm, sedangkan warna dibandingkan dengan referensi. Waktu yang diperlukan untuk mendapatkan warna dan tebal yang diinginkan kemudian dicatat. Hasil penelitian menunjukan jika waktu pemanasan yang terlalu lama dapat menyebabkan terjadi reaksi dehidroklorinasi sehingga warna kulit sintetis menjadi lebih gelap. Sedangkan kulit sintetis yang lebih tebal akan membutuhkan waktu pemanasan yang lebih lama. Akan tetapi perlu diperhatikan juga bahwa waktu pemanasan juga berhubungan dengan reaksi dekomposisi azodicarbonamide yang menghasilkan gas dan turut mempengaruhi ketebalan sampel.

“…According to Widhawardana [12], polyurethane l has adhesion strength that meets top coat standards, able to withstand heat, and can withstand corrosion rates of 24.36% in NaCl solutions and 45.66% in FeCl3 solutions. 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.…”

Corrosion can cause material damage due to the material's reaction with the environment. Corrosion will affect materials on construction, including metal material, thereby reducing the strength and the construction life, especially in a corrosive environment. The most effective and economical corrosion control is coating. The right coating application method will result in good bonding of the paint with the material, so that the corrosion protection will be better. This research used the ASTM A36 carbon steel material and polyurethane coatings. The purpose of this study is to determine the adhesion strength and corrosion rate by varying the application methods, namely brush, roll, and spray. In the pulloff test, the highest value of adhesion strength was obtained in the spray coating method with an average value of 20,82 MPa. Whereas in the three-electrode cell testing, the lowest corrosion rate using NaCl corrosive media was found in the spray coating method with a value of 0.000025402 mmpy and the lowest corrosion rate using FeCl3 corrosive media was found in the spray coating method with a value of 0.00182 mmpy.

“…The rheological, mechanical and thermal properties of the polyvinyl chloride (PVC) are dependent on the K-value and the various additives used in the formulation (Marceneiro et al, 2018;Sholeh & Rochani, 2018). K-value or viscosity number is an indicator of their molecular weight and degree of polymerization for the PVC used (Marceneiro et al, 2018).…”

Artificial leather offer wide variety of application thus the demand is increased over time. The variation of the product needs different properties that can be achieved using resin with suitable k-value.This works reports the influence of the resin k-value on the mechanical properties of the artificial leather. The combination of various resin with different k-value (66, 68, 72, 74, and 76)is used and the tensile strength and elongation at break of the product were evaluated. The results show that blending the PVC resin with different k-value can be used to adjust the easier processing of the lower k-value and better mechanical properties of the higher k-value. Larger k-value differences between two resin make more difficulties of resin blending thus give more defect. For the blending of two resin, the tensile strength and elongation value would be between both of the resin initial properties. The final properties will be closer to the resin with a higher percentage in the resin blending.
