Ive broken down the types of epoxy so you use the right one. I do need them to be 3d and moulded into a shape, Im not sure if there is a resin that would be suitable for this? One of the first breakthroughs in polyester production was in 1847 byBerzelius, who developed a reaction between tartaric acid with glycerol to form a polyester resin. Chemical resistance: Gel coats have good . Im ok with the slow firing, as tge heat ca crack the eggsbut if there is something that is a better option that would be amazing. Custom colors are available on request for an additional charge using . Im trying to wrap my head around hope to forward with a project and if resin is even the answer. The unsaturation present in this type of polyesters provides a site for subsequent cross-linking [23-24].Since 1930, unsaturated polyester resins have been used remarkably for wide range of applications making them a thermosetting system of major importance [25-26]. What resin would be best to use? Polyurethane resin like polyester resin can be used for casting molds. Later, the unsaturated polyester resin we know today was first developed byDaniel Vorlanderin 1894 utilising glycol maleates. I try to mix the concrete with epoxy resin and it worked.
