Powder Coating for  aluminum alloy profiles, aluminum curtain walls, aluminum doors and windows, aluminum ceilings 

 

 Super Weather Resistance Powder Coating

INTRODUCTION                                                                   

 Super Weather Resistance powder coating is a thermoseting  powder coating based on polyester resins specially selected for exterior use. It is formulated to give properties of good flow-out and satin or glossy finish. Its outstanding resistance to ultra-violet light and atmospheric aging make it highly decorative and durable in outdoor environment,It is provide with superior outdoor weather capabilities and outstanding chemical resistance, excellent hardness.  
 

 

• High temperatures up to 70 ºC
• Low customer temperatures in (Canada, Alaska) -50º to -60º  degrees Celsius
• Excellent corrosion protection and chemical resistant

GLOSS AND COLOR RANGE                                                                
 

• Gloss levels range from 70%- 90%  
• A wide range colors are available ,certain color is subject to the technical approval .

APPLICATION SCHEDULE                                                                   
 

• Applied by electrostatic spraying gun that can provide negative tension of 60-80 kV.
• Curing schedule :10~ 15 minutes at 200ºC (metal temperature )
• Optimal film thickness : 70 - 90 um 

POWDER PROPERTIES
 

• Specific gravity : 1.25 - 1.75 (depend on colors)

• Particle size distribution(Laser Particle size analyser) : Less than 4% above 100 um
  50 - 60% above 32 um :

Average particle size : 35- 45um


COATING PROPERTIES

The following are typical properties determined on 0.8 mm gauge degreased galvanised steel
 

• Film thickness (ISO 2178) : 70 - 90 µm
• Flow out : Good
• Gloss (ISO 2813, 60º) : 70 % ~ 90%
• Adhesion (ISO 2409) : GT= 0
• Pencil hardness(ASTM D3363 ) : 2H - 3H
• Direct and reverse impact (ASTM D2794) :  100-120kg.cm
• Salt spray Resistance ( ASTM B117, 1000hrs)
  (Maximum undercutting ,1 mm ): No blistering
• Humidity Resistance (ASTM D2247,1000 hrs): No blistering or loss of adhesion
• Chemical Resistance : Film unchanged

(96 hours contact with the coating at ambient temperature)

SUBSTRATES AND PRE-TREATMENT                                                        

In order to obtain optimal anti-corrosion properties, it is recommended to apply a chemical pretreatment prior to powder coating application.
 

• Ferrous metals(cold rolled steel, cast iron etc.): Iron or zinc phosphatation
• Zinc surfaces(galvanized steel, zinc alloy) : Chromatation or zinc phosphatation
• Aluminum alloys : Chromatation

STORAGE                                                                      
 

• Under dry conditions ,good ventilation at a temperature not exceeding 30 C,humidity < 60%.
• Storage period recommended should not exceed 6 months,in case exceeding 6 months without affecting their free flowing properties, the powder will still have optimal characteristics.
• Should be protected from excessive heat,humidity,water and contamination with foreign materials such as powder, dust, dirt, etc.
• Any leftover powder should be kept in an appropriate area that is cool and dry. Do not expose to the air too long as the powder properties may deteriorate with the moisture.

Q1: Are you a factory or trading company? 
A1: We are a factory manufacturing products for over 28 years in Jinhu, China. 
Q2: Why should I use powder coatings? 
A2: There are some advantages of powder coatings. For example, they are harmless to humans. In addition, they also have resource efficiency and reduction of environmental pollution. After being coating, it forms a lasting film to protect the surface of the items. 
Q3: Why should I buy from you not from other suppliers? 
A3: We have a professional group of R&D. According to our clients' preference, we can adjust the formula to change the color, luster, appearance, and even metal texture and special patterns.
