Oresin is a type of composite material used in the construction and design industries. It is a lightweight, durable and waterproof material which is used to create sculptures, architectural features, decorative objects, and more. Oresin is made up of two components, a resin and a powder. The resin is a combination of alkyd resins, acrylics and other polymers, while the powder is a mix of calcium carbonate, alumina, silica and other minerals. The two components are mixed together and poured or sprayed onto a surface, where they harden to create a unique, durable finish. Oresin is used in a variety of applications, including interior and exterior design, furniture, sculpture and more. It is an ideal choice for designers looking for a lightweight, waterproof and durable material to create unique and creative pieces.
