1. Description of High temperature powder coating

The High temperature powder coating produced by Milestone Industrial Co. Ltd. is a special functional coating. It not only has the properties of ordinary coatings, but also has heat resistance, corrosion resistance, weather resistance, etc., and can withstand temperatures above 450°C. High temperature, no yellowing, no cracking, environmental protection, safety, and high utilization rate.

2. High temperature powder coating physical properties: 

The proportion of: 1.0-1.8(It varies by color and gloss)
Particle size: 100% 30-60 μm
liquidity: 120-140

performance	Testing standard		Testing results
Burnish of 60 °		GB/T9754-88	1° to 95°+
Impact test	ISO6272	GB/T1723-1993	35cm/kg
Cup drawing test	ISO1520	GB/T9753-1988	5mm
adhesion	ISO2409	GB/T 9286-1998	Grade 2
Bending test	ISO1519	GB/T 6742-1986	4mm
Pencil hardness	ASTMD3363	GB/T 6739-1996	5H
High temperature test		GB1735-79	450℃/ long time 500℃/short time no cracking, bubbling, color has slight change
Note: 1. The above test is completed with 0.8 mm thick rust and oil removal cold rolled steel plate under experimental conditions, and the coating thickness is about 70μm;
2. The performance index of the above coating may be slightly reduced with the decrease of luster.

3. High temperature powder coating construction conditions: 

1) High temperature powder coating curing conditions: standard curing 230℃ (workpiece temperature) 30min
2) High temperature powder coating pretreatment: different substrates use different pretreatments (phosphating treatment, sandblasting treatment, shot peening treatment)
3) High temperature powder coating spraying: corona electrostatic spraying; friction electrostatic spraying; electrostatic fluidized bed spraying (required first); fluidized bed hot dip coating (required first); other spraying methodologies (required first) Claim).
4) Theoretical coverage of High temperature powder coating: 9-12 ㎡/kg, and the film thickness is 60 microns depending on the type and color.

4. Application range of High temperature powder coating：
MST High temperature powder coating is widely used in electric power, metallurgy, petroleum, aviation, chemical, pharmaceutical, food and other industries. For example, barbecue stoves, heaters, high-power lighting, heating pipes, hot blast stoves, silencers, ovens, high-temperature furnaces, motorcycle exhaust pipes, chimneys and other high-temperature equipment.

5. Storage requirements of High temperature powder coating

Store in a ventilated, dry, and clean room below 25°C. Keep away from fire, heating, and direct sunlight. Stacking in the open air is strictly prohibited. Under these conditions, the powder can be stored stably for 12 months. It can be re-inspected after the storage period, if the result meets the requirements, it can still be used.
