◎Coating Reference
1. Application: Factors such as plant capability, specifications, and pipe construction or
characteristics can affect application conditions. The recommended application temperature range for 3PE systems is 190-220ºC.
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 35ºC 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 polluted and damped.
5. Reduce the number of movements to avoid impact and pressure.
6. The maximum stacking height should not exceed 4 layers.
