It is a kind of flamboyant blue powder, which is the most durable and colorful inorganic pigment. Due to the characteristics of light fastness, weather fastness, alkali resistance, good dispersibility and heat resistance( over 350℃), it is ideal for plastics application. Ultramarine blue is innocuous and environmental friendly. | ||
