High build polyester has uniform and very fine
grain structure and can be produced with gloss levels of 35-45. It provides an optimum ratio between
flexibility and hardness and good resistance to weather influence. Suitable for low bend radius. Good abrasion
resistance. Typical end-uses are roofings, waterpipes. It is usually coated with 25µm high build primer.
