Polymer Products has polyester resin for casting. I know they sell PU blocks but I don't remember them having any liquid PU. I know where you can get PU foam for insulation but I don't think that's what you want.

Is polyurethane for casting the same as (two-part) polyurethane intended as a coating?

Ultracote -- http://www.ultracote.net/. For example, Ultracote 635 HB.

If there is no difference between polyurethane for casting and for coating , then I wonder whether epoxy can also be used for casting. For example, their Epotech 101 HB, Ultracote 213 HB, and Ultracote 282 cost less than their polyurethane, as do comparable epoxy products from other manufacturers.

Ultracote is located very close to the main office of Polymer Products, both off of C5 in Pasig.

Sure epoxy can be used for casting but it is rather an expensive resin for that purpose.

I think that may be true for some epoxies like of Cord or of Polymer Products, but there are also cheaper epoxies? Some prices last year:

Ultracote Epotech 101 HB -- P1,600/gal
Ultracote 213 HB -- P1,200/gal
Ultracote 282 -- P1,300/gal
Pioneer EFC -- P1,400/gal
Pioneer Perfect-Kote -- P1,200/gal
while Ultracote 635 HB polyurethane was P1,800/gal.

If there is any two-part polyurethane costing less than above, I would be interested to know.

Polyurethane we use can cure 5-6 minutes..How about epoxies?how is curing time. We use silicon rubber as mold.

Uratex bro ... but I suspect the cost won't be far from Polymer's.
