The binding agent consists of 100% acrylic resin for long-lasting results. Each tube is recyclable and clear, allowing artists to see the true colour and contents with ease.These paints are alkali resistant and this means they are suitable for wall and mural paintings. The paint can be thinned easily with water and, if applied in a thin film, paint can dry within half an hour. Lightfastness: ***Opacity: Semi-OpaquePigment Code: PR254
