I've been using the 'Amazing Casting Resin' and find it the best around for easy pouring and for strength of parts. Not to mention how quick you can pour and then de-mold and start again.
My first question has to do with post curing. I want the best strength i can get from the cured part, with all the great features mentioned in the data sheet. To achieve the best results, should i be expected to post cure the parts after pouring and they are de-molded? Maybe some heat for a few hours after de-mold would assure me of the best curing and end product. ?? Can't find anything about that in the directions or on the online site. Only a statement to the fact about proper portions of each a and b sides and such.
My second question has to do with the toxic nature of the cured parts. I know the two parts have toxic natures and need to be handled carefully. But what i'm concerned about is the cured part. I know urethane has off gassing and is not total cured until 72 hours normally. Talking about the 'Amazing Casting Resin'. The item i'm making does come in contact with food, yet is only momentarily and not like the food is stored in a container made with the 'Amazing Resin'. Should i be concerned even about a momentary contact with the properly cured 'Amazing Casting Resin'
Please, any help you can give me on these questions will be of great help.

Good Morning Rick,
We always recommend post curing thin cross sections for a uniform cure of your piece. Urethanes typically will have improved physical properties with a post cure application, so yes it is beneficial to post cure. Post curing safely it would be best to use a toaster oven dedicated to your casting applications (don't use your household equipment). Your cast pieces do best with low heat not to exceed 150°F for 2 - 4 hrs. Before you demold, let the pieces cool back down to room temperature. This procedure is leaving the pieces in the mold so you don't get any distortion or warping. Flat cast pieces can be cured out side of the mold as long as you have them on a very flat surface.
The Alumilite polyurethanes are not FDA compliant, our Amazing Clear Cast Epoxy is. We do not recommend using the urethane resins for anything that is going to be in contact with food. Using the Amazing Clear Cast for food applications still come with restrictions as follows; NOT dishwasher or microwave safe. Do not use to drink hot liquids from, or hot foods on serving dishes.
Have a great day Rick and enjoy the rest of your week.
