Lớp phủ phù hợp Urethane được biết đến với khả năng chống ẩm và hóa chất tuyệt vời.

Chúng cũng có khả năng chống mài mòn rất cao.

Do điều này và khả năng kháng dung môi của chúng nên chúng cũng rất khó loại bỏ.

Giống như silicone, việc loại bỏ hoàn toàn thường đòi hỏi dung môi chuyên dụng, thời gian ngâm lâu và khuấy trộn như dùng bàn chải hoặc bể siêu âm.

Lớp phủ phù hợp Urethane thường được chỉ định cho các ứng dụng hàng không vũ trụ, nơi tiếp xúc với hơi nhiên liệu là mối quan tâm chung.
