Curing Conditions

200~280℃ for 10-60 minutes. The higher the temperature, the shorter the curing time. Optimal curing at 220℃ for 30 minutes or 280℃ for 10 minutes. Best salt spray and chemical resistance performance under these curing conditions.

Usage Recommendations

1. It is recommended to first prepare waterborne non-resin color paste and then use it in combination with waterborne silicone resin emulsion.
2. The formulated coating has good room temperature self-drying properties. For excellent heat resistance and physical mechanical properties, it is recommended to fully cure at 200-280℃ for 10-60 minutes, preferably 220℃ for 30 minutes or 280℃ for 10 minutes.

Packaging and Storage

1. Packaging Specifications: 50 kg plastic barrels.
2. Store in a ventilated, cool place above 0℃, not exceeding 40℃. Transport as non-hazardous goods.

Shelf Life

Store in a sealed container for 6 months. (Each product label will indicate the "best before" date. Storage beyond the indicated date does not necessarily mean the product cannot be used, but the relevant properties should be rechecked to ensure quality).
