The product of an acid-glycol reaction commonly blended with a monomer to create a polymer resin. In its thermosetting form it is the most common resin used in the FRP industry.
Thermosetting resins which require the addition of a catalyst and accelerator to effect the cure. See also Epoxy Resin.
A polymeric ester resin used in making plastics, fibers, etc.
Thermosetting resins produced by dissolving unsaturated, generally liner, alkyd resins in a vinyl-type active monomer such as styrene. The resins are usually furnished in solution form, but powdered solids are also available. The resin used for unsaturated polyesters. Formed by the reaction of dibasic organic acids and polyhydric alcohols. Also meant to include the cross-linking diluent included with the polyester molecules.
Produced by combining polyester resin, aggregates, fillers, glass fibres pigments and catalyst. It can be laid over a cement screed or plywood. It is a hardwearing product with a wide colour range.
A group of synthetic resins that contain repeating ester groups. A special type of modified alkyd resin.
A polymer in which the structural units are linked by ester grouping.
Polyester Resin - Unsaturated Polyester Resin. The term generally used for unsaturated (means containing chemical double bonds) resins formed by the reaction of dibasic organic acids and polyhydric alcohols, basic component of SMC/BMC.
