4. Purpose:Suitable for producing mobile phone cases, pen motor cases, various plastic and hardware combination systems, hardware and alloy system cases, etc. for 3C products through in mold injection molding, die-casting molding, and two-color injection molding. The PU two-component primer, Primer treatment agent, cover primer, intermediate coating polishing layer, intermediate coating color paint, and primer and intermediate coating parts including three coating and three baking, five coating and five baking processes can be covered with PU and UV without affecting interlayer adhesion. RCA wear resistance and vibration wear resistance are both quite good.

5. Packaging and Storage:200KG、20KG; Sealed at room temperature and stored away from light for 1 year. If stored for more than a month, a small amount of sediment will precipitate at the bottom of the packaging barrel, which is an inherent characteristic of the product and does not affect its performance.

 

Please note:The above indicators and recommended performance are measured under fixed conditions and do not guarantee all usage purposes. For different usage purposes and conditions, users need to verify the formula themselves to ensure compliance with requirements.
