Deni Cahyadi, Daniel Fajar Puspita

Abstract


Research on acrylic emulsion wall paint formulation has been done. This research was aimed  to produce wall paint with 2 (two) criteria, that are complying Indonesian National Standard (SNI) and can be applied at home industry or Small Medium Enterprises (SME). The wall paint is water-based paint and produced with acrylic as the binder and other raw materials such as titanium dioxide, calcium carbonate, kaolin, tipol, ethylene glycol, ecocide, nofoam, texanol and disloid. Paint was made by mixing certain amount of raw materials in a certain  sequence, and stirred with certain duration. Paint was tested according to SNI 3564:2009,”Cat Tembok Emulsi”. According to test result, wall paint produced has covering degree (Pfund) 10 m2/L , density 1.48 g/mL, fineness 38 micron, touch dryness 6 minutes, hard dryness 10 minutes, total solid 57.1 % weight, pH 8.13 , viscosity 106 KU,  pass the weather resistance test and does not contain heavy metals ion. Based on the  result obtained, it can be concluded that the wall paint produced comply to SNI product specification.

 

Penelitian mengenai formulasi cat tembok emulsi berbahan acrylic telah dilakukan. Penelitian ini bertujuan agar cat tembok yang dihasilkan dapat memenuhi 2 (dua) kriteria, yaitu memenuhi Standar Nasional Indonesia dan dapat diterapkan pada industri rumahan atau Industri Kecil Menengah (IKM). Pada penelitian ini cat tembok yang dihasilkan merupakan cat berbasis air dengan menggunakan bahan pengikat jenis acrylic dan bahan baku lain seperti titanium dioksida, kalsium karbonat, kaolin, tipol, ethylene glycol, ecocide, nofoam, texanol dan disloid. Pembuatan cat dilakukan dengan mencampurkan bahan baku dengan jumlah dan urutan tertentu sambil diaduk dengan waktu tertentu. Cat yang dihasilkan diuji terhadap parameter uji sesuai dengan persyaratan mutu pada SNI 3564:2009, “Cat Tembok Emulsi”. Berdasarkan hasil pengujian, cat tembok yang dihasilkan memiliki daya tutup (Pfund) 10 m2/L , berat jenis 1,48 g/mL, kehalusan 38 micron, kering sentuh 6 menit, kering keras 10 menit, padatan total 57,1 % berat, pH 8,13 , kekentalan 106 KU, lolos uji ketahanan cuaca dan tidak mengandung logam berat. Dari hasil yang diperoleh dapat disimpulkan bahwa cat yang dihasilkan memenuhi persyaratan SNI 3564:2009.
