Masking off areas not to be coated when powder coating bus bars, cabinets, metal furniture, light fixtures, etc.
For applications that require short-term, high-temperature (400°F, 204°C) backing and adhesive that comes off easily and does not transfer. Typically applied by hand.
3M™ Polyester Tape is applied to mask off areas where the powder coating is not wanted. Tape needs to be rubbed down and pushed fully into inside corners. Die-cut parts can be made by the customer or by 3M per the customer’s specification. Powder coatings are paint films applied as dry powders, which are applied via a process of electrical attraction and then melted in an oven to form a solid film.
