Preparing and Powder coating push bike frames.
Here at Maldon Shot Blasting & Powder Coating Ltd carry out work on pushbike frames to a very high and long lasting standard.
Remember our motto do it once do it right. Our work will last you for many years to come, as powder coating is extremely chip resistant over stove or wet paints.
We are very aware that other’s offer a cheaper service, however we DO NOT cut corners and offer a professional service along with a five year anti corrosion warranty.
The frame material governs the approach we take on the first stage preparation.
If you know or believe any carbon fibre parts are present, please be sure to inform us, as carbon fibre is not a material that can be powder coated.
We do not apply naked flames to strip off paint or decals as some do, this can give rise to local distortion with disastrous results.
1. Steel frames are dipped in an alkaline paint remover then a light blast clean to remove all remaining paintwork and any corrosion and allow for a first class key for prime coat
2. Aluminium or alloy frames will be bead or aqua blasted this is less aggressive over blast cleaning and yet it still gives a first class key for the prime coat
3. Once the blast or bead cleaning stage is completed, the work visually checked over for damage as cracks or broken weld joints.
4. The frame and other parts are placed into our Phosphating and wash plant for final and complete deep clean, the phosphate helps further to etch into the work and therefore will give a far longer life.
5 .Masking off, all the threads and raceways making ready for the primer coats.
6. Apply our self-healing epoxy polyester primer coat at an average of 50 microns per coat.
7. Put through the semi curing stage @130d cent.
8. Apply the colour coat of polyester powder and fully cure until both the primer & topcoat have fully bonded to the work.
At this stage, we can apply either a further clear or special effect lacquer coats.
If you wish to supply decals we can apply them for you however they must be able to withstand a 2 pack clear coat, (check with your supplier first)
