Epoxy Polyester Powder Coating Specifications

Essential components of a powder coating are resin.

Epoxy polyester powder coating specifications.

Thermaset limited epoxy polyester powder coatings can be applied by manual or automatic electrostatic spray equipment general recommendation is for a film thickness of 60 100 microns depending on covering power and colour with a minimum recommendation of 60 microns. 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. This spec will pass over 1000 hours salt spray test and 3h hardness. 6000 series epoxy polyester hybrid systems these products have a broad formulating range that can meet many decorative and functional application requirements.

Epoxy powder coat one disadvantage of epoxy powders is their inability to weather well. Powder coating also offers a wide range of specialty effects that are hard to achieve through traditional methods. Typical applications for epoxy polyester powder coatings are those where a tough decorative finish is desirable such as domestic appliances and office furniture. When comparing polyester vs.

Excellent adhesion can be obtained through pretreatments of the metal involved including sandblasting and phosphate coating. 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. 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.

Tgic polyester powders can also be cured at lower temperatures making them ideal for cast parts and extruded parts. It has been used in applications involving steel pipeline coating concrete floor paint and even heat shields for space capsules. Hardener or curing agent. The surfaces of steel pipe piles to be coated shall be precleaned as required.

It is a powder that is easy to use and adheres to metals very well. 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. Yet they can rapidly lose gloss and begin to chalk when exposed to sunlight making them best suited for interior applications.
