Used to increase the relief of prints on paper, fabric and other surfaces. The microspheres in the Puff Additive expand with heat, giving you a raised print only after heating. Once puffed, the print is washfast and dry cleanable. Can be used on natural or synthetic fabric, paper, vinyl, metal and leather. This package contains 4oz of puff additive. Conforms to ASTM D 4236. Made in USA.
