Note: prepare specimens process
1) abrasive blasting to Sa2.5 near-white metal with surface profile of 50-100 microns. Then, cleaning the surface with high pressure gas
2) Put the specimen into the oven (200℃), preheat 40-60 min.
3) Spray the powder to the preheated specimen with electrostatic spray gun, then put it to the oven, keep 5-10 minutes at 200℃
4) The dry film thickness is 350±50µm.
◎Coating Reference
1. Application: Factors such as plant capability, specifications, and pipe construction or characteristics can affect application conditions. The recommended application temperature range is 200-220ºC.
2. Surface Preparation: Remove all surface contamination before abrasive blasting. Blast clean using steel grit to Sa2.5 near-white metal with a minimum surface profile of 2 mils/51 microns.
◎Precautions
1. All data are based on laboratory testing and practical experience.
2. It is recommended that the product should pass process evaluation before mass use, so as to avoid unnecessary loss to customers due to various reasons such as process.
◎Package and Storage
1. The package is 25kg per box, lined with polyethylene plastic bags. In the course of shipment, it should be loaded or unloaded lightly and avoid direct sunlight and heat and moisture.
2. The product should be stored in a cool, ventilated, dry room with temperature below 25℃ and humidity below 65%.
3. Keep away from fire and heat and tide.
4. After use, it should be sealed in time to prevent powder from being been polluted and damped.
5. Reduce the number of movement to avoid impact and pressure.
6. The maximum stacking height should not exceed 5 layers.
