Came across this link at polygem.com. A company that zoos ect use to build custom artificial rocks ect
http://www.polygem.com/products/zoopoxy/bonding-laminating/sinmast-4-1-gallon-kit
Has 3 different formulations. One is a slow set with a pot life of 50 minutes!
A fast set, and also says they have a semi hard/flexible formulation ( I'm interested in learnin more about this one )
There is a PDF on the link that shows the tensile strength ect of the epoxy
