How Powder Coating Stays ‘Green’
While we do offer a beautiful range of green powder coating colours, that’s not the type of green we’re talking about. Powder coating serves over 15% of the manufacturing finishing industry and is widely known as one of the most environmentally friendly options.
In addition to its amazing properties that serve to prolong the lifespan of metal items, the reduction of environmentally harmful factors is incredibly valuable. There’s no question as to why powder coating becomes increasingly popular.
Standard wet paints are generally carried by a solvent that will evaporate away as the paint dries, emitting harmful Volatile Organic Compounds (VOCs). Since powder coating is applied as a free-flowing dry powder, no VOCs are released into the atmosphere in production.
The powder is sprayed on, attaching itself via an electrostatic charge that is run through the metal, ensuring minimal spill or other wastage of powder. Our state-of-the-art Gema paint line also features a paint recycling system that captures and stores any powder that would otherwise be wasted.
The powder booth itself benefits from two ‘negative air’ type seals that work not only to maintain ideal temperatures but also to reduce powder blow off. The powder is then cured at high temperatures, which causes a chemical reaction that creates long molecular chains in high cross link density. This creates an amazing durability that beats standard wet paints every time.
Additionally, this impressive lasting power and resistance to damage means that paint rarely flakes away or otherwise escapes into the environment. Then, if you want to refresh the aesthetics of an item, the coating can be blasted off without using more harmful chemicals.
