HX-Body Latex and HX-Cosmetic Latex are both certified skin-safe by an independent laboratory, for paint-on-skin and cosmetic effects. Always review the current product documentation and perform a patch test before use. Do not use if you have a latex allergy.

With proper care, natural latex molds can last 10 or more years. Store molds in a cool, dry place away from direct sunlight and heat, and keep them covered.

Casting latex (pre-vulcanized latex) contains additives that allow the latex to cure at room temperature once all the moisture has left the rubber. Dwell time controls skin thickness as moisture is absorbed by the gypsum or plaster molds (about 30 minutes yields ~1/16 inch; a 2-hour dwell can produce ~1/4 inch). Castings typically dry in the mold about 12 hours after pouring out the excess latex before demolding.

Latex can be used for limited casting of some resins. The higher the exotherm (heat), the faster the mold will degrade. For high-volume resin casting, a silicone mold rubber is generally a better choice. PVA release can aid in releasing polyester resins from latex molds.
