Gel coating resin
A gel coating resin has different properties from a laminating resin. In general, a different type of resin or resin mixture is therefore used for gelcoat than for laminate construction. Either a special, finished gel coating resin is used, or a laminating resin is used with the addition of excipients (e.g. thixotropy agents or flexible mixing resins). The main properties a gel coating resin has to meet are fast curing, a certain elasticity and resistance to water, chemicals and weathering. for more info; https://www.v-sure.eu/en/products/polyester/polyester-gelcoat/
