Hanna powder coating is mainly composed of epoxy, polyester resin and conductive filler and metal powder. It is mainly used for anti-static and electrostatic elimination, providing indoor and outdoor conductive powder coatings（which can be adjusted according to the special requirements of painting.）
It is mainly used for the surface coating of automobiles, household appliances, metal furniture, instruments, indoor fitness and sports equipment, radiators and surface coating for other industries.
2 Physical properties
Appearance: uniform, loose, not conglomerate
Proportion: 1.1~1.8 (depending on type and color)
Horizontal fluidity: 18~35mm
Particle size distribution: 100% less than 125 um, of which more than 85% are between 60~90 um
3 Curing condition
Standard type ：180℃ (workpiece temperature) 15 minutes
Low temperature curing type ：160℃ (workpiece temperature) 15 minutes
The average rate of coating：the coating rate is 9-12 square meters per kilogram under the condition of the powder utilization ratio of 100% and the thickness of the film about 80 microns.
4 Storage requirements
Storage is less than 25℃, ventilation, dry, clean room, not close to the fire, heating, to avoid direct sunlight, strictly prohibit open-air stacking. Under this condition, the powder can be stored for 12 months. More than the storage period can be retested, if the results meet the requirements, can be still used.
5 Health and safety
This powder coating is a nontoxic product, but the inhalation of dust should be avoided in the process of use. Recommend the operator to wear the appropriate mask and glasses.
Characteristics of nylon powder
Advantages：Nylon powder has high mechanical strength, high softening point, heat resistance, low friction coefficient, wear resistance, with shock absorption and silencing, certain oil resistant, resistant to acid, alkali and solvents, good insulation, self extinguishing, non-toxic, odorless, good weatherability, poor dyeability.
Shortcoming：The water absorbability is large, which affects the dimensional stability and electrical properties
Application: widely used for spraying calendars, desk calendars, underwear hooks, and also for sports equipment, wire surface spraying, bridges, ships and other wire materials, spraying pipes and spraying engineering components.
Characteristics of epoxy resin powder
Advantages: the strong corrosion resistance of epoxy resin powder is the high quality anticorrosion coating of buried steel pipe. It has excellent chemical anticorrosion performance and high mechanical properties, especially the best wear resistance and adhesion.
Shortcoming: No protection against ultraviolet light.Long time be in Ultraviolet rays will Decolorization, extinction and powder.
Application: when the anticorrosion performance is the main requirement. Epoxy resin has excellent anticorrosion, impact strength and flexibility. It is mainly applicable to petrochemical pipeline, storage tank, metal structure, ship fittings and valves, etc.
Characteristics of polyester resin powder
First of all, it is divided into three categories: unsaturated polyester coatings, saturated polyester coatings, terephthalic acid polyester coatings
Unsaturated polyester coating:
Advantages: It has small environmental pollution, can be dry at room temperature, and can also be heated and solidified. The efficiency of spraying is high.
Shortcoming: In the curing process, the shrinkage rate is large, it is not easy to repair, and it is hard and brittle and easy to damage.
Application: It is mainly used for high grade wood furniture, TV set, coating and insulating material, sewing machine, coating of chemical storage tank and so on.
Saturated polyester coating:
Advantages:High gloss, good fullness, high hardness, good flexibility, good wear resistance and heat resistance, good light and color retention.
Shortcoming: It is not resistant to corrosion, and the repair performance is poor.
Application: Common outdoor items. Metal primer, automobile and varnish, outdoor decoration products, etc.
Terephthalic acid polyester coating:
Advantages:Good moisture resistance and insulation.
Shortcoming:Because of the existence of ester groups in the molecular chain, the water resistance is slightly poor.
Application:A motor spraying with a hot and wet belt.
Characteristics of the ring powder
Advantages:The most commonly used spray powder. As the main raw material was prepared using epoxy resin and polyester resin, and has both its own unique properties, the film produced has extremely good leveling, decoration, mechanical properties and strong corrosion resistance of the coating is widely used in various indoor metal products.
Shortcoming:The ability to resist UV is not as good as polyester powder. Corrosion resistance is not as good as epoxy powder.
Application:It is mainly used for the surface coating of automobiles, household appliances, metal furniture, instruments, indoor fitness and sports equipment, radiators and other industries.
