What is a good casting resin?

[Rolandranch]

I'm looking for a place to buy resin for casting pen blanks. I have no idea what is a good resin to use. I just need clear resin for casting rattlesnake skins, abalone, etc. I've been using PSI's resin that comes in the "cast-a-kit" but need a place to buy the resin alone.

I appreciate any help.
Thanks.

For me Silmar41 and I get it here. Polyester Resins

There are other places that may be a couple dollars cheaper but I always know it is fresh from that place.

I've had good results with Kast-A-Blank from WoodnWhimsies: Resin Casting Supplies | Page 1 of 1

No bubble issues using Ptownsubbie's molds with no pressure. YMMV, as they say.

Regards,
Michael

If you wish to stay with polyester resin (PR), Silmar 41 is what many prefer.

Two options:

USComposites

iLLStreet Composites

I don't have extensive experience with either company. Others can give you advice on which option might be a better choice for you.

I have a local source that distributes Silmar 41, which is manufactured by a Minnesota company, Interplastic Corp

Polyester resin: I really like Douglas and Sturgess Clear Casting resin - here:
Douglas and Sturgess: Clear Casting Resin, 1 Gallon

$45.00/gal, includes MEKP catalyst.

They also carry all the Mixol pigments, their own brand of fine pigments and tints, etc.

We're lucky to have a store in SF, and they've expertly served my sculpting, mold making, and casting need for years. (no financial attachment on my part)

Thank you all for your input. I just ordered a gallon of silmar 41 from IllStreet Composites. Looking forward to lots of casting!

For those of you using the Silmar 41, do you need to purchase a catalyst also? If so, which one?

No. Where I buy it that is included.

Where does allumilite come from? I've seen a lot of neat pens made from it and want to try it out sometime in the future.
