Some fiberglass fabrics we sell are finished for just polyester, some just epoxy and some are good for any resins. Here is a rough background on finishes. Finishes are put on glass fabrics to allow a strong bond between the resin and the glass. For example if you take a sheet of glass and put catalyzed resin on it, let it cure then try to peel it off it will come off easily with some effort. Finishes like Volan or Silane act as intermediaries between the resin and the glass in that they chemically bond to the crystalline glass structure with generally four of their available bonds leaving one bond with a suitable organic entity to bond to whatever resin is being used. Volan has been around a lot longer than the Silanes but is still one of the best finishes. Volan is generally the softest finish with some silanes being as soft as Volan. Volan is a chrome based finish that complexes with the silicon dioxide in the glass and leaves one group to bond to the resin. Silane is a molecule that, like carbon, has four groups (bonds) with three of them bonding to the silicon dioxide in the glass leaving one group to bond to the resins. Silanes are generally clearer and used a lot in surfboards. Volan is somewhat softer and yields a cloth better drape and is used more in open hand lay up applications. The type of finish on a particular fabric can make a lot of difference in the way it handles especially in it's ability to conform in intricate parts. Volan is generally softer than Silanes with some Silanes coming in not far behind. Just to give a little more details about how fiberglass cloth that when it is in the weaving process it has an oily starch type material on it to make the glass yarn slide a little easier to prevent breakage. After weaving is complete the cloth is heat cleaned to remove any of this material to make a better bond to the silane or Volan or other finish that is added afterward. The thread count and weave of the fabric can make a lot of difference in the the handling of the cloth as well. Some weaves are tighter than others and are not suitable for complex curves. The satin weaves will take complex curves better but are a little tougher getting the bubbles out. Satin weaves are also effected by the type of finish. This is probably because the yarn is closer together and allows cross bonding of the finish more than in plain weaves. For example, there's a tremendous difference in the way a satin weave like 7781 will be if it's finish in Volan or in a Silane. Some Silanes are pretty good while some can be pretty stiff and good for flat panels only. We sell the stiffer material for a good bit less than the softer material.
