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.


Quarts, Gallons, 5 gallon pails, 55 gallon drums.


One thinned gallon covers approximately 200 square feet with one coat.


Thin to spray viscosity with 9703 Butyrate Thinner, usually one to one.


For best results apply with a spray gun. Allow each coat to dry before spraying another. Do not rush coats; dopes work best when ample drying time is allowed between coats. In cool or humid weather, slow down application time or wait for better weather. Applying multiple thick coats applied in a hurry can cause film splitting or wrinkling.

Dry Time:

15 to 45 minutes depending on temperature and thinning.
