Powder coating, like spray coating, is used in various industries and for a variety of purposes, with the main reason being to offer more protection to surfaces. Unlike plasma spray coating, which is primarily used for thermal purposes, powder coating protects from corrosion and wear and tear while also providing an attractive finished look. However, despite its benefits, things like electroless nickel coating can also have some problems.
What Are the Health Hazards Relating to Powder Coating?
Powder coating is an important process in the manufacture of some machinery and appliances, yet it has risk factors for the environment and can cause harm to health if not used responsibly. This is why you must hire a trained and skilled professional like www.poeton.co.uk/surface-treatments/plating/electroless-nickel-plating to guide and assist with your project.
Those at the most risk of being affected by powder coating are those who work in the industry and are exposed to the substances used regularly through breathing in the powder particles or through direct contact with skin. This could cause asthma, skin irritation or sensitisation.
Are the Materials Used in Powder Coating Toxic?
While powder coating can be hazardous to those who work with it, some pigments and hardening agents in the make-up of the products are toxic, such as triglycidyl isocyanurate, or TGIC, tri-mellitic anhydride, or TMA, and lead chromate based pigments.
Like most powders, powder coating products are classed as hazardous to health in legal terms because they are breathable dusts and can easily enter airways, even though some elements of the powder making up around 10% of its composition will disperse naturally in the air.
To cut back on the damage to health and the environment, those in the sector are encouraged to follow health and safety protocols, which recommend proper disposal of materials, suitable washing and changing facilities and wearing appropriate PPE or personal protective equipment, which should include a face mask. These control measures should be regularly reviewed and updated to ensure that systems are being followed and that the powder coating practice is operating responsibly.
