Green step Jotun Paint School 38 © Copyright Jotun TSS Academy 1 Day Paint School Mengapa Cat Diperlukan? Ada dua alasan utama untuk mengecat : Untuk melindungi properti dan untuk alasan kosmetik Hal ini secara finansial sangat penting untuk melindungi struktur terhadap korosi. Sebuah sistem cat yang baik akan menjadi metode biaya-efektif untuk melindungi struktur: Umur struktur diperpanjang, biaya pemeliharaan berkurang dan resiko kecelakaan yang mempengaruhi orang-orang dan lingkungan berkurang. Jotun Paint School 39 © Copyright Jotun TSS Academy 1 Day Paint School Why do we paint? Safety and economy: The industry wishes to preserve their investments to avoid accidents. If it was cheaper to let constructions corrode, and simply build new ones when the safety limit was passed, we would have seen many more rusty plants, ships and platforms Jotun Paint School 40 © Copyright Jotun TSS Academy 1 Day Paint School What are differences between below terms?
