Epoxy Polyester Powder Coating Specifications

Typical applications for epoxy polyester powder coatings are those where a tough decorative finish is desirable such as domestic appliances and office furniture.

Epoxy polyester powder coating specifications.

It has been used in applications involving steel pipeline coating concrete floor paint and even heat shields for space capsules. Essential components of a powder coating are resin. Excellent adhesion can be obtained through pretreatments of the metal involved including sandblasting and phosphate coating. The list goes on and we could get into better scratch resistance toughness and hardness than traditional liquid paints but let s take a look at some of the different powders used that help achieve these characteristics.

Powder coating also offers a wide range of specialty effects that are hard to achieve through traditional methods. Epoxy powder coat one disadvantage of epoxy powders is their inability to weather well. It is a powder that is easy to use and adheres to metals very well. Vapour degrease immersion zinc phosphate 1st coat of powder coat zinc rich primer and 2nd coat of nylon modified polyester powder.

It offers many benefits for industrial and commercial painting applications. The resin and hardener part together is known as the binder. Tgic polyester powders can also be cured at lower temperatures making them ideal for cast parts and extruded parts. Epoxy polyester powder coatings based on specially selected resins to give the hard durable finish associated with epoxy coating but with superior heat stability and exterior durability.

The surfaces of steel pipe piles to be coated shall be precleaned as required. 6000 series epoxy polyester hybrid systems these products have a broad formulating range that can meet many decorative and functional application requirements. This spec will pass over 1000 hours salt spray test and 3h hardness. Yet they can rapidly lose gloss and begin to chalk when exposed to sunlight making them best suited for interior applications.

This specification covers standard requirements for pipe piles with protective fusion bonded epoxy powder coating applied by the electrostatic spray flocking or fluidized bed process. Tgic polyester powder coating films on the other hand can be applied with greater ease as they can be sprayed at thickness greater than 3 mils 75µm. As the name indicates in fusion bonded epoxy coatings the resin part is an epoxy type resin. Epoxy is a tough and multi purpose material consisting of the cross linking of an epoxy resin and hardener or co reactant.
