We use a single coat of hybrid powder for most of our products. Powder coating process involves following three major steps. They have applications in the automobile, telecom and construction industry. Powder coating requires curing at elevated temperatures for cross linking of polymers. TGIC Polyester powders can also be cured at lower temperatures making them ideal for cast parts and extruded parts. The inter-national standard for protective paint sys-tems is ISO 12944. Similar to Polyester Urethane Powders, TGIC Polyester powders are often used in power transmission and automotive industries. It is important to factor in the types of powder coating when deciding what types of powder coating service may be best suited for specific applications. Thermoset types of powder coating creates a non-reversible chemical cross-linking reaction that results in the change in physical properties. They offer very good mechanical properties, corrosion and chemical resistance and due to the presence of polyester, hybrid coatings chalks less and can be used in outdoor as well. They have seen rust near edges and inside corners. PVC coatings are pliable, sleek and durable coatings. wet paint or powder coating. A thermoplastic powder coating is one that melts and flows when heat is applied but continues to have the same chemical composition once it cools and solidifies. Acrylic coatings are highly glossy, smooth appearance and perform better than epoxy coating in sunlight. 6 Types of Industrial Powder Coating Materials Epoxies: Generally easy to use, comes in a variety of colors, and durable. In this way cleaning and pre-treatment process improves powder-coat quality.

This field is for validation purposes and should be left unchanged. The Different Types of Powder Coatings 1. There are different types and kinds of powder coat colors. Hybrid powder coatings are very similar to Epoxy Powder coating systems as these types both offer good corrosion protection. Powder coating is a surface finishing option that applies a relatively thin film to provide excellent corrosion protection and chemical resistance in a highly cosmetic manner. PVDF Fluoropolymers always need a primer beneath them – whether liquid or powder and are much more difficult to bond when creating metallic powders. Polyesters coating has very good adhesion, abrasion and UV resistant properties. Chemical etching and conversion coating are used to improve metal adhesion properties and corrosion resistance. Acrylic 4. They offer strong resistance to a wide range of solvents and oils, as well as damage caused by impact and abrasion. Following types of. Polyvinyl Chloride (PVC) 2. Powder Coating is the application of a dry powder using an electrostatic method and then heating the component to cure it. We use cookies to ensure that we give you the best experience on our website. Increasing quality requirements, more demanding usage conditions and longer warranty periods create a need for veri-fied data on the durability of coatings. The characteristics of the different types of powder vary widely, as well. But does that mean it’s the right choice for your job. These coatings have excellent adhesion with smooth surface finish. Powder coating occurs in three stages: Pretreatment, coating and curing: 1. Uniform visual appearance across a coated area regardless of part orientation. While parts are often designed with specific colors, gloss, and textures – the types of powder coating are often overlooked, yet a critical component to every powder coating job. A. FEVE resins are the most popular within the powder community for their superior one coat capability and incredible exterior performance. Some of the most popular types of powder coating include: Epoxy Powder Coatings; Polyester Powder Coatings; Hybrid Powder Coatings. Polyolefin powder coats are resistant to abrasives and chemicals. Following are the advantages of powder coating metal parts compared to liquid paint. Therefore thermoplastic type of powder coat are not recommended for high temperature or heated environments. Hybrid Powders; Hybrids represent a range of epoxy – polyester powders. Therefore when powder is sprayed towards parts using compressed air from the electrostatic gun. Everybody knows that cleaning and pretreating a surface is a key step in ensuring a fantastic coating job and we all want to put our best work out there – for ourselves and for our customers.

In the widespread world of powder coating, it is worth knowing that not all powders are equal in terms of quality, type and material usage. To sum up, dry powders are available in various materials, colors and special effects such as stain, glossy etc. In pre-treatment, parts are cleaned and undergo surface preparation as recommended by the powder manufacturer. They are extremely durable and offer (quite possibly) the best resistance to chemicals and corrosion of all the powders available. They are specially formulated according to the Indian climatic conditions and … But which one is best for your needs? Thermosetting powders work much the same way, except that the curing process alters their chemical … 3. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. FEVE based … There are two types of powder coats, thermoplastic and thermoset. High temperatures can melt thermoplastics. Therefore  it is recommended for outdoor applications such as furniture and automobile parts. Following types of powder coat are available according to dry powder chemical composition and its cross linking structure. They also provide high resistance to chemicals and impact but are best suited for interior surfaces because they wear down quickly when exposed to elements of weather. POWDERS WE COAT.
