Since developing the first water based artist acrylic paints in 1955, Liquitex has focused on providing all of the tools needed by the professional artist. All Liquitex products are formulated by a unique team of chemists and artists. This combination allows them to make the most versatile ranges of intense, highly loaded, permanent colours possible. The low-odour acrylic resin base represents the latest in acrylic resin technology, offering increased open time and producing colours of great clarity. The paint films are highly flexible, durable, non-yellowing, UV resistant, water-resistant and pH neutral when dry. All Liquitex Professional Colours can be intermixed with each other and Liquitex Mediums.
