1Receive product requirements from customers. Please provide a color sample — it can be a finished product standard color, masterbatch, or Pantone Index Number.
-
2Please inform us of the applied resin, your device type, and whether the intended use is indoor or outdoor.
-
3Please provide clear notes on any special requirements, such as RoHS, FDA, or UL certification.
-
4Make a sample according to the customer's color sample. Generally, the sample lead time is 2–3 working days. For urgent cases, please notify us specially.
-
5Arrange mass production after confirmation and approval of the sample's color and performance.
Products use double-layer packaging: the inner layer is a waterproof, moisture-proof polyethylene film bag; the outer layer is a paper-plastic composite bag. Standard package: 25 kg / bag.
Please store in a ventilated, dry place, elevated from the floor, away from direct sunlight and rain. The masterbatch color shelf life is up to 5 years. After opening, reseal the remaining contents to prevent dust contamination and moisture absorption.
