Fibreglass resin is a polyester.
Some alternatives to epoxy resin for your project include polyurethane, polyester resin, and UV resin. Each of these materials has different properties and may be suitable depending on the specific requirements of your project.
as polyester resin is a bi-product of oil so if the prices of oil rise then it is definite that the polyster resin price will also rise.

Once polyester resin cures (hardens) through a chemical reaction—usually with a catalyst like MEKP—it forms a rigid, cross-linked structure that cannot be melted or reshaped again. This irreversible curing process is the key characteristic of thermosetting materials. In contrast, thermoplastics soften when heated and can be remolded multiple times, which polyester resin cannot do after curing. That’s why polyester resin is widely used in fiberglass, boat hulls, automotive parts, and construction—applications where heat resistance and structural strength are essential.

Some effective alternatives to epoxy resin for crafting and DIY projects include UV resin, polyurethane resin, and polyester resin. These alternatives offer similar properties and can be used for a variety of projects like jewelry making, coating surfaces, and creating art pieces.
