Coil Powder Coating Manufactory-low emission powder coating factory

• 

Coil coating is a continuous industrial process in which multiple layers of organic film are applied and cured on a moving metal strip. The paints used are liquid (solvent-based) and are generally composed of polyesters with acid- or hydroxy- endgroups able to crosslink with melamines or isocyanates to form a complete network with film properties that are tailored to the final application of the coated metal panel (building products, beverage cans, domestic appliances, etc.).

The total film thickness is around 5 to 25 µm, which allows for perfect color matching, surface hardness and transformation of the flat panel through bending or shaping without damage. The paints that are used for this application are usually based on a thermoset system involving catalyzed chemical reactions at temperatures around 240°C.

The main advantages of coil coating are its fast cure time – approximately 25 seconds – and its ability to create an already-painted substrate that is flexible enough to fabricate parts.

Common Types of Coil Coating

Caigang paint is known as coil coating or pre-coated (or pre-bake) coatings.

General metal products are later coated metal substrate molding mat, and some are first continuous metal coil coating, high temperature dried and then rolled, and finally press molded into a variety of products need to be processed. These coils can be steel (including galvanized, galvanized aluminum, etc.) and aluminum, which is used in paint Color paint.

Common Types of Caigang Paint

Paint is made of resin, pigments, solvents, additives (adjuvants) four kinds of raw materials, of which the resin Color paint performance play a decisive role, accordingly, can be divided into the following types:

Polyesters

Flexibility, adhesion and mold ability, inexpensive varieties, color, luster selective large, is the most important finish, widely used in interior and exterior building materials, home appliances, and transportation;

Polyvinylidene fluoride based

Various properties were excellent, especially the outstanding weather resistance, especially durable, but expensive, used for facades, also applies to polluted areas;

Polyvinyl fluoride type

As a thermoplastic coating, coating thickness, toughness, formability good, especially resistant, can be used for embossing, it is widely used in serious pollution of the environment, such as ships, tanks and smokestacks and the like;

Silicone modified polyesters

Light, heat resistance, high hardness and durability, but flexibility, adhesion and moldability relatively polyesters poor, the price is higher than the polyester type, used for facades;

Epoxy resins

Has good adhesion and corrosion resistance, is generally used as a primer;Others such as modified alkyd resins, acrylic resins and polyurethanes have a certain purpose.
