How To Repair a Torn Urethane Rubber Mold

[@GiggidySquad]

Will this work on a small piece of rubber like a rubber band?

[@smoothon]

Rubber bands are not generally made of urethane. We would recommend testing a single-component adhesive for that application.

Can this be used on platinum Tin silicones?

I'm late to the party here , but will this only work for urethane molds?.......what about silicone?.....tin cure and platinum cure?

For Silicone molds you're going to want to use a silicone adhesive. Sil-Poxy by Smooth On is a great choice. It can be quite messy compared to Ure-Bond if you're unfamiliar with it, so you might also want to purchase some NAPTHA and a paint brush so that you can clean any of the excess silpoxy off of areas you don't want it. I don't recommend using standard platinum silicone from a hardware store to repair tears in molds. You can make molds out of it and they'll turn out fabulous, but it doesn't quite work to bond torn silicone.

Dang I didn't realize this comment is 4 years old. Oopsies. Hopefully this helps someone else at least.

Can this be used to repair urethane foam as well, like flex foam-it?
