WebEvonik’s methacrylate monomers are widely used in polymer composites as reactive diluents, crosslinkers, and raw materials for polymer synthesis. Basic methacrylates such as VISIOMER® MMA are widely utilized as co-monomers with styrene in unsaturated polyesters resins (UPR) for enhanced weather resistance of gelcoats and laminate resins. Since reactive diluents are incorporated into a lacquer or resin and remain in it, they influence not only the viscosity of the uncured lacquer but also its physical properties after curing. Therefore, the choice of the reactive diluent has an influence on: • The adhesion of the lacquer to the substrate • The compatibility with the binder
