Orthophthalic (UPR)
The economical, general-purpose grade for fibreglass repairs and non-structural parts.
Resins & binders
Polyester resins
Unsaturated and saturated polyesters for composites, coil and powder coatings.
Polyester resins divide into two families: unsaturated polyesters (UPR) — the standard thermosetting liquids behind fibreglass-reinforced plastics — and saturated polyesters, the durable binders behind coil, can and powder coatings.
Types & classifications
Isophthalic (UPR)
A premium grade with superior tensile strength and water and chemical resistance — for marine use and plumbing.
DCPD blends (UPR)
Low shrinkage, low odour and a glossy finish for automotive and sanitary-ware parts.
Saturated polyesters
Linear and branched grades crosslinked with isocyanates or amino resins — for coil, can and powder coatings with excellent weatherability.
Key applications
Marine & composites
Boat hulls, decks and fibreglass-reinforced parts with an excellent strength-to-weight ratio.
Construction
Architectural panels, roofing sheets, skylights and corrosion-resistant tanks and pipes.
Transportation
Lightweight, impact-resistant body parts and interior panels.
Coil & powder coatings
Flexible, hard and weatherable finishes for pre-coated metal, architecture and appliances.
