Hazardous chemicals in powder coating activities

Triglycidylisocyanurate (TGIC) TGIC is classified as a hazardous chemical and is commonly used in powder coating activities. It is: a skin sensitiser toxic by ingestion and inhalation genotoxic capable of causing serious eye damage. You should check SDSs and labels to determine if the powder coat colors you are using contains TGIC. Electrostatic powder coating containing TGIC are applied by electrostatic process.Workers who may come into direct contact with TGIC powder coatings include persons: filling hoppers manually spraying powder paint,Read More …

Two common types of ventilation in spray painting

Two common types of ventilation used in spray painting are: Local exhaust ventilation captures the overspray and solvent vapour as close to the source of release as possible by drawing the contaminants into a capture hood. They should be fitted with a particulate filtration system to filter overspray. Wherever possible, local exhaust ventilation should be used when a spray booth cannot be used. It may be necessary to use it in combination with other control measures. Information on local exhaustRead More …

Maintenance of spray equipment

You should ensure that the plant and spray equipment used in spray painting or powder coating activities is well maintained, operational and clean. This includes: regular visual checks of equipment and plant, including engineering controls and ventilation systems regular monitoring and testing of ventilation flow rates regular servicing of all equipment and plant procedures for reporting and repairing faulty equipment records of servicing, maintenance, repair and testing of plant and equipment should be kept for future reference. When undertaking maintenanceRead More …

Conditions for Dust Explosions

During powder coating application , the conditions for dust explosions must be paid attention highly to avoid any problem occur . A number of conditions must exist simultaneously for a dust explosion to occur. The dust must be combustible (as far as dust clouds are concerned, the terms “combustible”, “flammable” and “explosible” all have the same meaning and could be used interchangeably). The dust must be dispersed (forming a cloud in air). The dust concentration must be within the explosibleRead More …

Pearlescent Pigments

Pearlescent Pigments Traditional pearlescent pigments consist of a high-refractive-index metal oxide layer coated onto a transparent, low-refractive-index substrate such as natural mica. This layering structure interacts with light to produce constructive and destructive interference patterns in both the reflected and transmitted light, which we see as color. This technology has been extended to other synthetic substrates such as glass, alumina, silica and synthetic mica. Various effects range from satin and pearl luster, to sparkle with high chromatic values, and hue-shiftingRead More …

How to maintain metallic effect powder coating

How to maintain metallic effect powder coating Metallic effects arise through light reflection, absorption and mirror effect of the metallic effect pigments contained in the paint. These metallic powders can be used in both exterior and interior environments. The cleanability and suitability of the powder,for an environment or end use, starts with the colour selection process. In certain instances the powder manufacturer may propose the application of a suitable clear topcoat.The cleaning of metallic effect powder coated surfaces is inRead More …

Steel coil coating process

These are the basic steps of the steel coil coating process UNCOILER After visual inspection,moves the coil to the uncoiler whereby the steel is placed on a pay-off arbor for unwinding. JOINING The beginning of the next coil mechanically join to the end of the previous coil,this allows for the continuous feed of the coil coating line. This makes each edge of the joint area become the “tongue” or “tail” of the finished coated steel coil. ENTRY TOWER The entryRead More …

Effect of surface treatment of inorganic pigments

Surface treatment of inorganic pigments After the surface treatment of inorganic pigments, application performance of pigments can be further improved ,and the results fully reflect its optical properties,that is one of the main measures to improve the quality grade of pigments . The role of a surface treatment The effect of surface treatment can be summarized into the following three aspects: to improve the properties of the pigment itself, such as the coloring power and hiding power;  improve performance, andRead More …
