For years we have been researching and making alkyd paints. This research has led us to the development of C.A.S. AlkydPro Paint. Finally, artists have another choice for alkyd-oil paint. C.A.S. AlkydPro Paint is the first line of true alkyds made in the United States, and the first line of genuine Artist's grade alkyds. Unlike some fast-drying oils available today, our paints are made entirely from an Alkyd Resin Base. We did not start with a traditional linseed oil paint and simply add alkyd resin—our paints contain no linseed oil. Our new improved formula for the entire line is made with a non-yellowing sunflower alkyd oil for the highest performance.This is a unique paint. We are now offering 56 luminous colors and three mediums, providing artists with a full range of color and creative potential.
