Is there an industry standard for film build on thermoplastic powder coatings? L. M.
Answer:
There are no industry standards for film build on thermoplastics, but your powder coating supplier may have some recommendations. Typically, thermoplastics are applied at thicknesses greater than one mil and can be applied to more than 20 mils. Much of the film thickness recommendations from your powder supplier depend upon the particular grind (particle size) of the powder and the flow characteristics of the material. For instance large grind powders cannot be applied at thin film builds (less than two mils). Furthermore, thermoplastic powders that have high flow characteristics for a smooth surface cannot be applied too thick without causing a sag in the coating. Check with your supplier for the proper film thickness requirements for your particular thermoplastic powder coating material.
