polyesterplaster
Polyesterplaster is a plaster-like composite used for coatings, repairs, and decorative work. It combines unsaturated polyester resin with mineral fillers, pigments, and sometimes reinforcing fibers. The resin binds the fillers into a rigid, lightweight mass, and additives such as fiberglass may improve tensile strength where needed. The formulation is designed to cure at ambient temperatures to produce a surface that can be formed, finished, and painted much like traditional plasters.
Curing occurs through a polymerization reaction initiated by a catalyst. The process is exothermic and has
Compared with cementitious plasters, polyesterplaster offers faster cure, lighter weight, and a smoother, more uniform surface
