Frequently Asked Questions
What is Powder Coating?
Powder coating is a type of dry coating, which is applied in the form of a dry powder. The main difference between powder coating and standard liquid paint is that the powder coating does not need a solvent to keep the binder, fillers, pigments, extenders and resin in a liquid form. This leads to a more environmentally friendly process.
How does the application process work?
The normal application process for this environmentally friendly powder coating is via the electrostatic charge method (the paint is sprayed and a charge is applied to the powder cloud) after which it is cured under heat to allow it to flow and form a ‘skin’ layer.
What products can be coated?
Northpoint has clients from various industries including oil and gas, construction and water treatment. Powder Coating is used for coating metals such as steel fence components, gates, gate posts and other architectural structural steel components.

Is there a guarantee?
At Northpoint we strive for 100% customer satisfaction; that’s why we offer a standard 10 year warranty and provide high quality to ensure that the life expectancy of powder coating is 25 years. The Interpon D range has a 30 year warranty (all subject to terms and conditions).
How is the coating environmentally friendly?
Powder coating does not emit (many) volatile organic compounds (VOCs) and therefore has a significantly reduced impact on the environment. Any ‘over-spray’ from powder coating can be recycled, producing less waste and making the process more cost-effective. Powder coating production lines produce less hazardous waste than standard liquid coatings and have a significantly thicker coating film.
