Style 7645 is an 8 harness satin with the same weight at 1582 but with a count of 46 x 42 ends per inch is slightly lower. 7645 uses the yarn ECG 75-1/2 in the warp and fill, has a breaking strength of 562 x 518 lbs/inch and a thickness of 0.0133". We have in stock 49.5" width with the CS-550 finish that's a hybrid of the chrome base Volan and silane and is good for any resin. We have the 7645 in 50.0", which has the S-550 finish and also Volan finish. The S-550 is generally not as soft as Volan and is not to be confused with the CS-550 finish - though structurally similar to the S-550 has been, in our experience, not as soft as CS-550 though nearly the same. Volan has always been the softest finish. The following rolls are priced accordingly. There's also some 60" in Volan.  All prices do not include shipping unless specified.  For further information please contact us.
