Overnight Cure Urethane Elastomers - Flexible
Urethane rubber is generally less expensive than silicone rubber and more abrasion resistant, making it a preferred material for concrete and architectural castings. However, flexible urethanes are not self-releasing and therefore require a more thorough procedure (wax and PVA) to facilitate clean and easy part release.
