Pebeo Studio Acrylics Bindex DYNA is a pigmented, translucent, acrylic binder with fluid consistency which offers a flexible waterproof film after drying. Bindex is used to prepare acrylic colours. When mixed with the colours it provides an even colour consistency, allows better adhesion, transparency, depth, drying time without thinning the paint. Gloss Bindex DYNA is used in the same way as the Gloss Bindex but, being developed from interference pigments, applications will change colour with the angle of refraction of the light. It is ideal for creating collages and inlays. It's also commonly used in bookmaking and bookbinding.
