Hybrid powder coatings are a blend of epoxy and polyester resins used primarily for indoor applications. They offer improved penetration into corners and recesses (Faraday Cage areas) and are less sensitive to overbake on curing than many other chemistries, making them suitable for use on appliances, radiators and other temperature-sensitive applications.
Polyester Powder Coatings allows long-term exterior durability, high performance mechanical properties & over-bake resistance. Polyester powder is widely used for decorative parts where a good resistance to sunlight (ultraviolet rays) are required. Many automotive trim components & other exterior parts are coated with polyester powders.
Epoxy Powder Coatings allows toughness, corrosion resistance, chemical resistance, flexibility, adhesion & abrasion resistance. Epoxy powder is normally used where a tough, durable film is required with limited exposure to direct sunlight (chalk-like appearance after extended sun exposure).
ACRYLIC resins are typically used in the automotive industry as a clear coat on materials. Acrylic creates a smooth clear coat with very good clarity and provides - better than a clearcoat made of different types of powders - a hard surface that is highly chip-resistant. Acrylic resins are used as additives to promote improved flow and leveling as well as enhanced stain and chemical resistance in polyester hybrid, polyester TGIC, and polyurethane powder coatings. The typical curing cycle is similar to polyester finishes, but may require extra time and temperature for high stain & chemical resistant finishes. Example: 20 minutes @ 190°C (375°F) or 10 minutes @ 204°C (400°F)
Nylon is a thermoplastic. Meaning its chemistry does not change when it is melted to the metal part. Nylon will melt and re-melt if the metal part is heated again. Nylon coating powder is aesthetically attractive when applied properly but is never specified simply because it looks good. Costing more than 3 times the typical paint or powder finish, nylon is specified for functionality IE: slip, sound dampening, flange linings, and medical case brackets. Other types of parts we apply nylon to are: drive splines, glove box strikers, door strikers, seat springs, and various clips and clamps used in the aerospace and auto industries. Nylon powder for use in coating metal can be purchased in two chemistries: nylon 11 or nylon 12. What is the difference? The chemist may argue there are plenty of differences, however, practically speaking Nylon 12 is slightly less hygroscopic than Nylon 11 (less than 1%) Nylon 12 typically will have lower gloss, and nylon 12 may be slightly less expensive to purchase depending on the amount ordered. When buying nylon, gloss can not be specified. Generally, nylon 11 is around 70 gloss. Nylon 12 is typically 30 gloss. Gloss level will be the same batch to batch, and will only vary depending on the manufacturing process. Nylon is considered a "softer" coating, easily machinable, but can not be easily marked with a fingernail.
A fluoropolymer is a chemical compound that contains many strong carbon-fluoride bonds. The fluorine in a fluoropolymer is electrically negative, which gives it the property of not bonding easily with other materials. That's what makes a fluoropolymer non-stick. A fluoropolymer is an umbrella term, and it includes many other products with trade names that you may have heard of, including Teflon, Excalibur, Algoflon, Xylan, Solef, and Fluon. The first fluoropolymers was developed in the 1930s, but hundreds of variations now exist. Fluoropolymers are in high demand for use in industrial coatings because they possess some very desirable qualities. First, fluoropolymers have excellent non-stick properties, as evidenced by their use in non-stick cookware. Also, fluoropolymers reduce friction and resist corrosion. They withstand very high temperatures, as well. Fluoropolymers are insulators, meaning they do not conduct electricity. They do not absorb water, either. This combination of factors makes them ideal for use in electronics, automotives, and many other uses. Fluoropolymer resins are top of line for exterior weatherability and UV stability in both powder and liquid coatings. Fluoropolymer powder coatings are purposely tailored for the architectural market and offer a long-life durable finish. Fluoropolymer powder coat resin systems can be formulated to meet the requirements of the high performance AAMA 2605 specification. These finishes are resistant to moisture, weathering, ozone and UV radiation. An application for this finish would include architectural projects that require long term cosmetic and functional protection.
PVC based coatings offer many advantages over the other thermoplastic materials available as binders for coating production. These coatings have very good resistance to many solvents, which is a rather poor characteristic of the thermoplasts, combined with resistance towards water and acids. They have excellent impact resistance, salt spray resistance, food staining resistance, and good dielectric strength for electrical applications. Polyvinyl chloride is one of the cheapest polymers produced by the industry on a large scale. Its basic properties include chemical and corrosion resistance, good physical strength and good electrical insulation. Polyvinyl chloride (PVC) is by nature a brittle polymer, but the flexibility of the material can be easily adjusted by using an appropriate amount of a suitable plasticizer.
Polyurethane powders have excellent flow characteristics with excellent chemical and mechanical properties. Outstanding corrosion resistance and excellent external exposure properties make them suitable alternative to polyester powders. GENERAL FEATURES Polyurethane powder contains polyurethanic resins cured with curing agents. The powder forms protective and decorative film along with enhanced outdoor resistance. The protective film have good resistance to mechanical damage, detergents, fuels and oils.
Inorganic powders do not contain carbon compounds. They only contain powders and by-products of inorganic material. Metal powders are inorganic by nature. Some of them can be made from different kind of stones like chalk, diamond or talc.
