POWDERCOATING 

Powder Choices

There are many types of Powder out in the market and the purchaser should be careful to choose the correct one for the application.

As is specified in the powdercoat colour selection section of our website, the choice of colour is also crucial to the long-term performance of the coating.

The chemistry of the main powder coating products manufactured for use on Architectural Aluminium falls into three brackets.

  1. Extra Durable Powder Coatings                 Extra Durable Coatings

  2. High Durability Powder Coatings               High Durability Coatings

  3. Super Durable Powder Coatings                Super Durable Coatings

The most important features to consider when choosing a suitable powdercoating can be broken down into 4 areas:-

  1. Advantages

  2. Disadvantages

  3. Availability

  4. Warranties

   

 

Powdercoating Warranties and the Design Environment 

 

1. Polyester Powder Coatings 

Polyester powder coatings are available in a number of grades:

Standard Polyester Powder Coatings are designed for Industrial Coating of products and equipment. They are not designed for coating joinery.

No warranty would apply if those powders were to be used on Architectural Aluminium Joinery.     

 

Extra Durable Polyester Powder Coatings are designed for:

bullet

Residential Developments

bullet

Buildings up to three levels above ground

bullet

Locations greater than 100 metres from salt water, in mild to tropical environments - click here to go to corrosion zone map

bullet

Welded aluminium sections greater than 100 meters from salt water

bullet

Where AAMA 2603-05 performance is required

bullet

Where a ten year colour warranty and a 10 year film integrity warranty are desired

bullet

Extra Durable Polyesters are not recommended for commercial developments and warranties normally will not apply to projects outside the parameters outlined above

 

High Durability Polyester Powder Coatings are designed for:

bullet

Prestigious residential and commercial developments

bullet

All major architectural developments irrespective of height

bullet

Properties located greater than 10 metres from salt water, in mild to tropical and some severe environments - click here to go to corrosion zone map

bullet

Welded aluminium sections greater than 100 metres from salt water

bullet

Where AAMA 2604-05 performance is desired

bullet

Where a 15 year colour warranty and a 15 year film integrity warranty is desired

bullet

High Durability Warranties will not normally apply to projects outside the parameters outlined above

 

2. Fluoropolymer Powder Coatings

Super Durable Fluoropolymer Coatings are designed for:

bullet

Monumental / landmark projects where product performance is under constant review

bullet

Developments irrespective of height and most environments

bullet

Properties greater than 10 metres from salt water - click here to go to corrosion zone map

bullet

Where AAMA 2605-05 performance is desired

bullet

Where a 20 year colour warranty and a 20 year film integrity warranty are desired

bullet

Fluoropolymer warranties will cover most substantial commercial projects.

           

 

What determines powdercoat pricing?

While there are many factors that influence the end price of PowderCoating the two below make up a good part of the variation in cost.  

1)     TYPE OF POWDER

2)     STOCKED ITEM

 

1)     There are many different types of powder available to be used on Architectural Aluminium and the correct one for each application should be chosen (use Powdercoating warranties and design environment).

Most powders in NZ have been made to withstand harsh UV conditions,  they are normally made as an Extra Durable product that will cover a good part of New Zealand , however, as conditions get harsher, such as coastal or Geothermal, then so the powder type should be upgraded. Powders that are designed to withstand these harsh conditions can cost more than six times that of an Extra Durable powder.

 Powders that are not solid colours such as metallics or pearlescents  can also be more expensive to manufacture and are reflected in some pricing.

 

   

2)     Due to the number of powders available including different types, colours, gloss levels etc it is impossible for the powder manufacturers or the applicators to stock all the variations of these. Unlike wet paint, powder has a limited shelf life and is manufactured as each individual product and cannot be tinted from a base colour.

Typically popular colours that are coated on a regular basis will be priced in one bracket, then powders stocked by the manufacturer but are only coated infrequently may be in another bracket. From here you can get into an area where special colours, types of powder and  "made to order" products may be priced. Where special powders are manufactured it is typical for all the powder to be charged out whether applied or not as the applicator cannot do anything with the left over.

Some of the higher durability powders have to be stoved (baked) for twice as long as some standard powders and this will also be reflected in the pricing.
