Based on the requirements provided, we recommended Geon™ M5705, a high flow vinyl molding material for outdoor use. The results of the evaluation gave Smart Hero the confidence to replace the painted metal with Geon M5705 material. Using Geon M5705 material for these seven colors will save an additional $200,000 per year.
