Definisi Protective Coating
Protective coatings atau lazim disebut cat menjadi salah satu pilihan yang paling banyak dipergunakan saat ini. Keunggulan cat telah menjadi terbukti efektif dan efisien menjadikannya menjadi suatu pilihan yang praktis dan ekonomis.
DefenisiCat dapat diartikan sebagai suatu produk cair atau kental yang
apabila diulaskan/disemprotkan pada suatu permukaan yang telah lebih dulu dipersiapkan akan membentuk suatu lapisan tipis kering, berkohesi, dan memiliki daya lekat yang baik terhadap permukaan dan dapat memproteksi permukaan tersebut dari ekses luar/lingkunganya.

Komposisi & Produksi
Komposisi dan Produksi
Cat dapat dibuat dengan mempergunakan beberapa jenis bahan baku yang berbeda, berbentuk cair dan bubuk diproses sedemikian rupa sesuai dengan spesifikasi dan formulasi menurut jenis cat yang dikehendaki. Secara umum, komposisi cat dapat dibagi menjadi lima bahan baku utama yakni:
BinderPigmentSolvent
ExtenderAdditive

System Proteksi Cat
Cara Cat Memproteksi
Tiga prinsip dasar, dimana cat dapat mencegah timbulnya korosi.
1.Barrier EffectMenciptakan rintangan atau hambatan yang kuat untuk memisahkan permukaan dari air dan oksigen. Dasar prinsip ini disebut BARRIER EFFECT.
2.Inhibitor EffectMemberikan peluang kepada air untuk menembus rongga-rongga pada lapisan dan melarutkan sebahagian campuran antikarat pada permukaan cat dan akan bereaksi terhadap korosi dasar prinsip ini disebut INHIBITOR EFFECT.
3.Galvanic EffectKontak langsung antara besi dengan logam yang potensialnya lebih lemah (missal : seng). Hasilnya adalah perlindungan katodik pada logam itu sendiri dasar prinsip ini disebut GALVANIC EFFECT.
