low temperature and UV powder coatings bring the benefits to heat sensitive substrates
Powder coating provides a durable, attractive and economical alternative to liquid paints and laminates for a wide range of heat-sensitive products such as glass and plastic materials. Powder coatings are dry, 100 percent solids paints that are spray-applied in a process similar to liquid painting. Once coated, products are conveyed through a curing oven, where the powder melts to form a durable, attractive finish. Powder coatings have long been the finish of choice for lawn & garden equipment, home appliancesRead More …
Performance innovations in powder coatings industry
Hygienic Powder Coatings Antibacterial powder coating recently developed can help prevent the spread of bacteria on products in homes, hospitals, restaurants and food-processing plants. High Temperature Resistant Powders Silicone-based powder coating are often used on products that are subjected to prolonged periods of high heat, up to 1,000ºF, and hold their color, gloss, and adhesion. Some of these products include gas and charcoal grills, fireplace inserts, engine exhaust components, and light fixtures. Thin-Film Powders Powder manufacturers are developing more powdersRead More …
HEAT-SENSITIVE SUBSTRATES is popularly welcomed in coatings industry
In recent years, ongoing research and development has been devoted to formulating powder coatings that can cure at low temperatures, below 212ºF, without compromising durability or quality. These powders can be used on temperature-sensitive materials, as well as on massive parts that require enormous amounts of energy with other curing systems. Wood materials such as particle board and fiberboard, as well as glass and plastic products, can now benefit from a powder coated finish — products that would deform orRead More …
Many new performance characteristics are available in today’s powder coatings
Many new performance characteristics are available in today’s coatings, from antibacterial properties to the ability to be cured by ultraviolet or even near-infrared radiation. Advanced Durability Recent research and testing has developed specially formulated polyester powder coating that provides even greater weatherability than achievable in previous years, and showing greater success in long-term Florida exposure testing. New TGIC-based powders are being used on outdoor stadium seating and other exterior applications that were previously susceptible to degradation from ultraviolet rays. LightRead More …
Some of the newest color innovations in powder coatings
Color variety is almost limitless these days, with many coatings suppliers offering a pallet of off-the-shelf colors, as well as custom color-match services to better meet the needs of small-volume powder users. There are also tints that can add highlight color to a substrate or base coat, such as a brass look over polished aluminum. A range from flat to high gloss is generally available. Smooth, high-gloss coatings can offer high distinctiveness of image, creating an illusion of depth orRead More …
Nanotechnology is rapidly gaining recognition to provide significant benefits for the coatings industry
Nanotechnology is rapidly gaining recognition as having the potential to provide significant benefits for the coatings industry. The most publicized benefits include scratch resistance, UV protection and weathering protection. In addition to improved coating performance, nanotechnology also provides benefits, such as reduced energy and reduced material consumption. Nanoparticles including metal oxides, clays and resins dominate the market for nanotechnology-based coatings. Newer carbon based nanotubes are now being developed for use in transparent conductive coatings and low weight, high strength coatings.Read More …
Titanium Dioxide (TiO2) the most important and widely used in the coatings industry
Titanium Dioxide (TiO2) is the most important and widely used white pigment in the powder paint and coatings industry. Its combination of optical and physical properties make this pigment suitable to bring needed performances for a wide range of different coating applications. Incorporated correctly , this pigment helps to tune up the formulation to obtain many properties such as superior gloss, brightness, tint strengh, ease of dispersion, durability, hiding power and batch to batch uniformity. TiO2 is used to opacify paintRead More …
How to control the quality of matting agents dispersion in powder coating or paint
When we use fillers as matting agents in powder paint or coatings it is advisable to measure Grindometer or Hegmann value in order to receive information about the dispersing degree. Second, we can control the gloss degree at an angle of 60°. For the other above mentioned product groups the main parameter should be the control of gloss behavior. However, in order to get an extensive understanding about the matt degree of the paint it is necessary to take measurements atRead More …
Matting addtitives for powder coating or paint
Related Article: Powder Coating Raw Material All the matting additives which are used in the powder coatings or paint field, have their benefits and advantages. Waxes Today, there is a diverse range of waxes on the market. The most used waxes for coatings and inks are based on Polyethylene, Polypropylene, Carnauba, Amid. Waxes products based on Polytetrafluorethylene PTFE are also used as matting agents. In contrast to silicas, waxes modify the surface properties of a paint film by floating toRead More …
