Product Description

White Color Epoxy Polyester Hybrid Powder Coating Smooth Glossy for Home Appliance


Thermoset powder coatings are a category of powder coatings that are applied to a surface as a dry, fine powder and then cured through the application of heat.

Unlike thermoplastic coatings, which can be re-melted and reshaped, thermoset coatings undergo an irreversible chemical reaction during the curing process that makes them extremely durable and resistant to wear and tear, and therefore more commonly used for high-heat applications.
 

Industrial manufacturing
Thermoset powder coatings are used, and in fact, often preferred in the manufacturing industry to protect metal parts and components from corrosion and other types of wear and tear. They are especially popular in the automotive, aerospace, and military industries, where parts need to be able to withstand extreme conditions like high levels of heat, chemical exposure, and stress.

Architectural applications
Thermoset powder coatings are also used in the construction industry to protect the exterior surfaces of buildings and other structures. They exhibit excellent resistance to weathering, fading, and chalking, making them the ideal choice for use on the exterior of buildings and other structures left to withstand the elements and test of time.

High-use equipment & fixtures
Thermoset powder coatings can be found on tools and equipment you can find around you every day, such as push carts, hand rails, public benches and shopping carts to name a few. Their superior durability versus other coatings become crucial for high-traffic and high-use applications where repeated use can sometimes wear a protective coating down quickly.

Appliance and consumer goods
Thermoset powder coatings are also used to protect the surfaces of appliances, such as air conditioners, refrigerators and washing machines, as well as consumer goods like indoor & outdoor furniture and electronics. They provide a durable, long-lasting finish that can withstand daily use and cleaning.


 

GLOSS AND COLOR RANGE                                                                
 

• Gloss levels range from 50- 90% and above
• 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 minutes at 200ºC (metal temperature )
• Optimal film thickness : 60 - 80 um 

POWDER PROPERTIES
 

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

• Particle size distribution(Laser Particle size analyser) : Less than 5% above 100 um
  50 - 65% 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) : 60 - 80 µm
• Flow out : Good
• Gloss (ISO 2813, 60º) : >50 %

(48 hours contact with the coating at ambient temperature)
(Hydrochloric acid 10%,Hydrogen sulphide (saturated),Hydrogen peroxide 40 vol,Ammonium hydroxide 33%,Sodium hydroxide5%,Tartaric acid 5%,Citric acid 5%, Lactic acid 5%, Ethanol, n-Butanol)

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 25 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.
