Frequently Asked Questions

What does 40A mean?
It is the Shore A hardness rating. At 40A the cured silicone is flexible enough to demold easily while still holding fine shape detail.

What is the mix ratio?
It mixes 1:1: equal parts of Part A and Part B, kneaded until the color is uniform.

Can I use the mold for food?
Rolio markets this putty for craft, resin, soap and wax molds, not for food-contact molds.

What can I cast in a silicone putty mold?
Makers commonly cast epoxy resin, UV resin, soap and wax. Do a small test cast with any new casting material.

Color your castings with Rolio pigment pastes and mica powders.
