It was found that hybrid modification of unsaturated polyester resin by chemical modifiers and laser treatment increased the hydrophobic and anti-icing properties of polyester gelcoats. Unsaturated polyester resins (UPRs) are solutions of unsaturated polyesters in co-polymerizable monomers, which undergo cross-linkage to form thermosetting plastics. Unsaturated polyester resins are mostly used in combination with reinforcing materials such as glass fibres, that give life to the FRP (an acronym deriving from the English), a polyester reinforced with glass fibres, better known with the name of fiberglass. As a result there is a whole range of polyesters made from different acids, glycols and monomers – with combination of … UNSATURATED POLYESTER RESINS PRODUCTION.
