I have attempted to cast a model using Easy Composites' Fast Cast Polyurethane Casting Resin. The cast failed as the resin did not fully cure. Half the model cured but the rest came out like thick honey, see image above. I'm not sure why this happened, but my immediate problem is, how do I clean the uncured resin goo from my mold? The mold is made of RTV silicone.

How long did you cure and at which temperature?

If you think you mixed the A+B well at good ratios you could still try to put it into an oven or hope for it to fully cure
