Coats required. Water-based polyurethane is considerably thinner than oil-based products. Due to this lower viscosity, water-based polyurethane contains 30 to 35% solids versus 45 to 50% for oil-based products. The difference means you'll require one and a half to two times as many coats of water-based polyurethane for the same protection.
Solvent-based coatings are in the process of being phased out of the market due to their health risks and other negative factors. Water-based coatings are overall safer to utilise and are not nearly as harmful for humans nowadays.

Mari kita pelajari keduanya untuk mengetahui apa saja yang dimaksud dengan solvent based dan water based. Solvent based Cat dengan bahan pelarut minyak atau solvent ini adalah bahan pelarut yang dapat menguap dengan adanya reaksi kimia antara bahan pelarut dengan oksigen. Secara umum, tidak ada perbedaan berarti saat aplikasi cat water based dengan wat solvent. Yang jadi soal, ada pada jenis bahannya yang berpengaruh pada efisiensi aplikasi cat. Contoh paling sederhananya, adalah sebelum mulai proses mengaplikasikan cat, dilakukan pengadukan bahan cat dengan pelarutnya. Proses ini perlu dilakukan dengan benar. Cat kayu campuran air sering disebut dengan cat water based dan cat dengan campuran thinner sering disebut dengan cat solvent. Warna kayu natural atau warna kayu solid sama-sama memiliki jenis dengan bahan campuran atau pelarut tersebut. Acid-based DES and 20-30% water resulted in the highest anthocyanin extraction yield from samples compared to sugars and polyol-based DES. Ultrasonic-assisted extraction was the most common and efficient method for anthocyanin extraction. ChCl:glycerol-based solvent resulted in the highest values of TAC (2.61 mg CGE g −1) and individual udGjsi.
