Aluminium powder coating and surface treatments for bonding

If you are looking for a dependable powder coating partner who cares about your business outcomes, you are in the right place.

Getting to know you and your products is at the heart of what we do. Through building a close working relationship with you we can be responsive to your business needs – helping you to keep the promises you have made to your customers.

What is powder coating?

The powder is paint in dry powder form, made of resins, binders and pigments. It picks up an electrostatic charge as it leaves the end of a spray gun and becomes attracted to the metal substrate. The coating is then cured by heat to form a smooth hard skin of uniform thickness on the surface of the metal. This is a very different process from wet paint spraying with time saving and control over process variables being big advantages.

Powder coating is a one-coat system and after application the coat can be cured in 20 minutes, whatever the weather.

Benefits of powder coating

The powder coated surface formed by the curing process is a bonded layer with excellent resistance to weather corrosion, scratches, abrasions, chipping and fading.

  • Being dry, powder coatings have no solvents containing volatile compounds.

  • Powder coatings are a dry powder and emit zero or negligible volatile organic compounds (VOCs).

  • Powder coatings contain no halogens or heavy metals.

  • Powder coatings do not produce hazardous waste. The process takes place in sealed booths and 95% of what is sprayed adheres to the metal or is collected, filtered and re-used. Any powder left over is safely disposed of as an inert powder.

  • Powder coating takes place in factory-controlled conditions so there is no on-site impact.

  • Powder coating does not mean ‘end-of life’ status for the metal. The coating can be removed and the metal recycled with no adverse effect.

Pre-treatment for powder coating

We use only chrome-free pre-treatments in our plant and were the first powder coater in the UK to do so, back in 2001.

We have extensive experience in these safe and effective systems.

Our TiZr chrome-free pre-treatments are eleven-stage Gardobond® X4591 and Gardobond® X 4707 processes. Gardobond etch passivation techniques and Henkel Bonderite M-NT 2040 give equivalent levels of protection.
