Vinyl esters are a type of synthetic resin created by the reaction of an epoxy resin with an unsaturated monocarboxylic acid, such as acrylic acid or methacrylic acid. They are known for their excellent mechanical properties, chemical resistance, and durability, making them suitable for various applications, including coatings, adhesives, and composite materials. These resins are often used in the manufacturing of fiberglass products, where they provide a strong and lightweight alternative to traditional materials. Vinyl esters can be processed using various techniques, including hand lay-up and spray-up, allowing for versatility in production methods.
