POLYESTER

Frequently asked questions

General purpose resins are the most widely used products in the industry. They are typically used for:

  • Hand laminating and fibreglass repairs
  • Swimming pool linings and waterproofing
  • General composite manufacturing

They are available in two primary chemical formulations:

  • Orthophthalic (Ortho) Resins: Best suited for general-purpose, cost-effective applications.
  • Isophthalic (Iso) Resins: Formulated for higher structural strength and better environmental resistance.

While both provide a protective and aesthetic surface finish, they are applied at different stages of production:

  • Gelcoats: Applied directly to the mould surface before laminating. It cures to become an integral, high-gloss, and UV-stable outer layer of the finished product. It can be tinted to almost any colour.
  • Flowcoats (Topcoats): Applied after the initial fibreglass and resin laminate has been laid down. It is used as a final interior or exterior sealing coat to finish swimming pools, boat interiors, and repairs.

Polyester putties and bonding pastes are highly filled, viscous compounds used primarily as high-strength structural adhesives. They are ideal for bonding core materials like Balsa wood and structural foams to your laminates.

Vinyl Ester resins are a high-performance hybrid of Polyester and Epoxy technologies. You should choose Vinyl Ester when your project demands outstanding chemical resistance (such as chemical tanks or marine hulls) and superior structural resilience against heavy impacts or stress.
