Chemical resistance generally good resistance to acids alkalis and oil at normal temperatures.
Polyester powder coating thickness.
I am trying to determine what film thickness range i should specify.
Thermaset limited polyester powder coating can be applied by manual or automatic electrostatic spray equipment an even dry film thickness of 60 70 microns is recommended.
Whether you re new to powder coatings or an experienced pro you re probably well aware that powder coating is a fantastic painting method that creates a tough durable and beautiful finish.
An abrasion test carried out by the paint research association in 2003 compared the abrasion resistance of nylon coating to two types of polyester coating bonalux and interpon the results showed nylon to offer an expected lifespan of over 7 times that of bonalux and almost 6 times that of interpon.
Since the 1980 s we ve been meeting customer quality expectations and matching environmental regulations.
Powder coatings offer a cost effective green easy to apply and durable coating.
Nylon is more resistant to wear and abrasion.
No matter whether you re using a single gun and small oven or a large fully automated line the process is basically the same.
The trick there is to maximise opacity by thicker film build but avoiding orange peel.
Are there any guidelines for film thickness for a powder coating operation.
To the most commonly used polyester powder forms are.
The coating thickness varies on different products and in different colors.
Manufacturers provide a production specification sheet for powder coat materials.
The powder may be a thermoplastic or a thermoset polymer.
As the most routinely used powder coating polyesters provide excellent value for the money.
A tgic resin lead pigmented polyester powder would probably be okay at 60 microns.
Powder coating thickness may also affect the application s impact resistance flexibility hardness edge coverage chip resistance weathering resistance to salt spray and ability to retain gloss.
Reds yellows oranges are the problem children.
Yes there are some resources that can help you identify the correct film thickness.
Both provide great impact resistance and flexibility good mechanical resistance and good chemical resistance.
It does have a low cure temperature.
Powder coating is a type of coating that is applied as a free flowing dry powder unlike conventional liquid paint which is delivered via an evaporating solvent powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
