Jesmonite® AC730 Flex Liquids are supplied as an alternative to standard AC730 Liquids to create laminates with increased flexibility. The Flex liquids are also ideal when Jesmonite AC730 is used as a coating for Polystyrene for external sculpture - the increased flexibility reduces the likelihood of cracks forming in the coating due to moisture build up and thermal movement. The use of Flex liquids also means that Jesmonite paste pigments can be used to create colourful casts for external use**. Flex liquids are also compatible with Jesmonite Flex Metal Gel Coats.
