9701 Tautening Butyrate Dope is used to shrink and seal organic fabrics, Grade A cotton and Irish Linen. Apply in multiple coats until the fabric reaches an acceptable level of tightness. Due to its shrinking characteristics, it is not recommended for use on Ceconite or other polyester synthetic fabrics.
Polyester fabrics are shrunk primarily by heat; also applying a tautening dope after heat shrinking could produce undue tightness and deformation of the underlying structure. 9701 Tautening Butyrate dope is the recommended product for use on organic fabric rather than 201 Tautening Nitrate dope.
