Epoxy and polyester resin
Fiberglass profile is a composite material combining glass fibers with a resin — the fibers deliver strength and stiffness, while the resin provides adhesion and toughness. The resin type used in fiberglass profile can significantly shape the profile’s final properties.
Epoxy and polyester rank among the most common resin types used in fiberglass profile.
Epoxy Resin
Pros:
Highly resistant to chemicals, making it a good choice where chemical exposure is a concern.
Also highly heat-resistant, suiting applications where high temperatures matter.
Good mechanical properties, well-suited where strength and stiffness are priorities.
Easy to work with, a good fit for complex applications.
Cons:
More expensive than polyester resin.
Harder to cure than polyester resin.
Polyester Resin
Pros:
Costs less than epoxy resin.
Easier to cure than epoxy resin.
More forgiving than epoxy resin, a good pick for beginners.
Cons:
Less chemically resistant than epoxy resin.
Less heat-resistant than epoxy resin.
Lower mechanical properties than epoxy resin.
