TGIC replacement chemistries in powder coating-Hydroxyalkylamide(HAA)
TGIC Replacement chemistries Hydroxyalkylamide(HAA) As the future of TGIC is uncertain,manufacturers are searching for an equivalent replacement for it. HAA curatives such as Primid XL-552 ,developed and trademarked by Rohm and Haas,have been introduced. The chief drawback to such hardeners is that, since their cure mechanism is a condensation reaction, films that build to thicknesses exceeding 2 to 2.5 mils (50 to 63 microns) may display outgassing ,pinholing ,and poor flow and leveling . This is especially true when theseRead More …
Characteristics of electrostatic powder coating spraying
Electrostatic powder coating spraying because he does not use the solvent will not cause solvent pollution in the atmosphere, while avoiding the danger of fire due to the solvent, is also easy to transport and storage of raw materials. The spraying process, the overspray powder is not coated on the workpiece can be recovered, the recovery rate of up to more than 95%, to improve the utilization of raw materials, to reduce the material consumption costs. Superior film performance, betterRead More …
Characteristics of the electrostatic spraying
Generally speaking, where does not occur at 200 ℃ deformation, enables the charged powder particles are adsorbed on the surface to be painted, the surface coating can be by electrostatic powder spraying. Therefore, electrostatic powder coating spraying technology can be widely used instruments, household appliances, mechanical and electrical equipment, automobile and shipbuilding, light industry equipment, furniture, machinery and building materials, and other metal parts of the surface protection and decorative painting. View from currently used in spray technology, electrostatic powderRead More …
Classification of electrostatic spraying nozzle
Electrostatic spraying can be divided into the way the air or hydraulic atomizing electrostatic spraying, centrifugal electrostatic spraying, etc.; direct nozzle electrostatic spraying, electrostatic spray of Y-type nozzle target nozzle electrostatic spraying can be divided according to the different characteristics of the nozzle; in accordance with the paint can be divided into the different nature of the solid powder electrostatic spraying and electrostatic spraying of liquid atomization. Widely used in the coating of the plate surface of the electrostatic powderRead More …
Powder coated wood is Green Friendly and Healthy Lifestyle
The powder coating wood process is environmentally responsible since the powder coating wood process has no VOC’s or dangerous chemicals, as a matter of fact there are no environmental permits required for powder coating wood so the application process is very environmentally responsible.The materials are very green friendly.Also, powder coated wood can offer a healthy lifestyle benefit using antimicrobial additives from DuPont which will can remove 99.9% of the surface bacteria, plus since this finish is seamless there are no crevices for bacteria to hide and foster. This is a greatRead More …
Controlling the moisture content in the MDF is critical
The powder coating process requires an electrostatic charge for the powder to attract to the wood while using a premium grade MDF. This electrostatic charge is created by heating the wood to bring the moisture content to the surface, since it is this moisture that serves as the electrostatic conductor.The adhesion of the powder to the board is so strong that to remove the powder finish from the board it is likely the MDF board substrate will chip off before the powder will chip away from the MDF. This process requiresRead More …
Powder coated wood finish has catapulted a huge increase in demand
The design industry has always had to compromise with the trade-off between form vs. function. Advancements in powder coated wood finishes make it possible to have the best of form and function.It is now possible to use more shapes and contoured profile edges in designs, blending this with the functional benefits of a very durable powder coated finish. Powder coated wood has the look and shape that designers and architects can use to create unique designs without the limitations of many other surfaces. AnRead More …
