Application and Safety
Make sure the mold is clean and free of oil and dust. From 20–25 cm (8–10 in), apply a thin, even coat using steady spray-and-release strokes. Start and end each stroke off the surface and wipe away excess if needed. Review the SDS for ventilation, ignition-source control, handling and storage requirements. The 260 °C rating refers to the mold process, not safe storage or heating of the aerosol container.
