Powder Coating for Architectural effect is a great way to make and keep buildings and their elements weather resistant and looking good for years into the future.

ICS strongly recommends using a dual coat system for any exterior architectural powder applications. By including the Zinc-Rich epoxy based powder coating under the more UV resistant top powder layer, you are significantly increasing the durability and life span of the coating system.

ZINC-RICH PRIMER Zinc Rich Epoxy Powder Primer

The zinc properties of our primer coating layer attempts to mimic the properties of traditional galvanizing, by sacrificing the electrons in the zinc before the metal substrate can. Additionally, the properties of the epoxy in this layer are highly resistant to chemical attack, including water and other forms of environmental corrosion.

SUPER DURABLE POWDER Decorative Architectural Powder

Polyester powders are very resistant to ultraviolet light degradation. All of the RAL colors are formulated in this type of material. Even better though are ultra polyester powders that can provide even more protection from sunlight damage. ICS stocks several Super Durable powders, but typically, you might expect to have a custom formulation to get Super Durable powders in custom color choices.

How do I know how a coating will perform?

According to the AAMA, it is generally not possible to devise short-term tests that will give positive correlation with service because the tests must be accelerated by increasing the severity of exposure. Laboratory tests are set up to screen coatings, and the selected coatings must then be evaluated under actual service conditions. If a given material performs better in carefully selected laboratory tests, the formulator is generally confident that it will also perform better in actual service

The most common testing methods used to compare coating quality are briefly described below.

What is the main difference between Powder and Liquid

Powder coatings are made without solvents. Consequently, they emit ultra low levels of VOC's when they are manufactured and factory-applied to a metal substrate.

Powder coatings have other environmental advantages. For instance, there is less waste in the application and recovery of powder coatings, which may make powder coating production lines more efficient. Powder coatings also require less manufacturing and transportation energy.

Salt Spray Test Salt Spray Corrosion Test ASTM B117

5% salt solution is sprayed at 92-97F in sealed weather cabinet onto test panels. An X is scribed into the phosphated test panel and the test ends after ¼” of corrosion creepage from the scribe is observed. The hours to reach this point of failure is then recorded (no less than 500 hrs).

Impact Hardness Test Impact Test ASTM D2794

A ½” Gardner impact test ball is dropped onto the test panel at 26 inch pounds of direct impact. There should be no loss of adhesion or grazing on the test panel for a successful test.

Pencil Hardness Test Hardness Test ASTM D3363

Faber Castell wood pencils are used in hardness of 1-4. By scraping across the test panel, no marks shall be left from 2H hardness pencil. The hardest pencil is a 9H, followed by 8H, 7H, 6H, 5H, 4H, 3H, 2H, and H. F is the middle of the hardness scale; then comes HB, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, and 9B, which is the softest.
