Link Powder Coating and Metal Finishing can carry out a range of pre-treatments to ensure the best possible finish before the final colour is applied.
Removal of oil, dirt, lubrication greases and metal oxides is essential prior to the powder coating process. It can be done using a variety of chemical and mechanical pre-treatments.
One of the pre-treatments we carry out most often is de-greasing. Any metal component that’s been machined, drilled, swaged or sawn is likely to have oil or grease on its surface which must be removed before coating. This is done by spraying, brushing or wiping a cleaning agent onto the component.
Once the surface is clean, applying a primer before powder coating can offer added protection to the metal work. Having a primer under the powder coat adds extra strength to protect against corrosion and ensures good adhesion of the final colour. Ultimately it helps ensure both the best possible finish as well as a longer lifespan of that finish.
We can also carry out shot blasting or bead blasting to clean the metal and ensure an even texture – please visit our metal finishing page for further details.
The choice of method, or methods, depends on several things. The size and material of the part to be coated. The types of impurities to be removed. The performance required from the finished product. Our friendly and experienced staff will give you an honest opinion about which pre-treatments, or combinations of pre-treatments and metal finishing techniques, are needed or recommended.
