Polymers
Tri-Art Polymer Medium is used for thinning and extending any viscosity of acrylic paint. This translucent medium dries to a clear, flexible film that has excellent resistance to water and ultraviolet radiation. Polymer Mediums are extremely adhesive and can be used in collage and craft applications such as decoupage. Polymer Mediums can be added to resoluble water based paints such as watercolours and gouache to increase water resistance and flexibility. The Semi-Gloss and Matte Polymer Mediums add a small amount of tooth to a surface and dry to a more translucent finish.
