Epoxy

Epoxy adalah suatu kopolimer, terbentuk dari dua bahan kimia yang berbeda. Ini disebut sebagai "resin" dan "pengeras". Resin ini terdiri dari monomer atau polimer rantai pendek dengan kelompok epoksida di kedua ujung. Epoxy resin Paling umum yang dihasilkan dari reaksi antara epiklorohidrin dan bisphenol-A, meskipun yang terakhir mungkin akan digantikan dengan bahan kimia yang serupa. Pengeras terdiri dari monomer polyamine, misalnya Triethylenetetramine (Teta). Ketika senyawa ini dicampur bersama, kelompok amina bereaksi dengan kelompok epoksida untuk membentuk ikatan kovalen. Setiap kelompok NH dapat bereaksi dengan kelompok epoksida, sehingga polimer yang dihasilkan sangat silang, dan dengan demikian kaku dan kuat. Proses polimerisasi disebut "curing", dan dapat dikontrol melalui suhu, pilihan senyawa resin dan pengeras, dan rasio kata senyawanya; proses dapat mengambil menit untuk jam. Beberapa formulasi manfaat dari pemanasan selama masa penyembuhan, sedangkan yang lainnya hanya memerlukan waktu, dan suhu ambien. 

  

Korosi

Korosi (corrosion) atau karat sebenarnya adalah gejala kebalikan dari proses produksi besi dari bijihnya. Bila membuat besi dari bijih besi memerlukan usaha yang sangat sulit, tetapi pada proses korosi justru sebaliknya. Bahan korosif malah akan dengan sangat mudah tergerus habis dan kembali menjadi bijih agar bisa menyatu dengan alam.

Sandblasting

Sandblasting is a general term used to describe the act of propelling very fine bits of material at high-velocity to clean or etch a surface. Sand used to be the most commonly used material, but since the lung disease silicosis is caused by extended inhalation of the dust created by sand, other materials are now used in its place. Any small, relatively uniform particles will work, such as steel grit, copper slag, walnut shells, powdered abrasives, even bits of coconut shell. Due to the dangers of inhaling dust during the process, sandblasting is carefully controlled, using an alternate air supply, protective wear, and proper ventilation.

Surface Preparation

Surface preparation is the process of removing preexisting coating(s), residue, organic matter, oxidation, or other contaminants from a surface, and it can range from a basic wipe-down or sanding to a total stripping, using tools and equipment designed specifically for the surface and coating at hand.
