Spunfab is described as "an adhesive webbing prepared from [a?] plasticizer-free,  
high molecular weight, semi-crystalline, polar copolyamides"  Is anyone aware of any testing that has been done or further information on its chemistry and working properties?  I was looking at the Spunfab as an optional adhesive to add to areas where an old fabric can no longer be attached properly by itself [a modern roller shade assembled by a contemporary artist]. To my  surprise Spunfab actually works very nicely but I  do not think I can use it because I cannot find any aging tests or
any information beyond the above. Does anyone have any ideas how it ages? If you do I'd appreciate learning as much as I can about it, if not perhaps you could direct me to another information source.
Thank you for your help
