Polyesters
Overview
Polyester resins are the most widely used resin for everyday applications such as marine , swimming pools or canopies. Polyester resins are ideal also for making moulds or doing repairs on boats, roofs or any other job
Polyester resins can be used in numerous applications, however described here is a abridged list of products that Duroplastic supplies to the industry.
General purpose resins are normally for any use from laminating, repairs, swimming pool lining , etc. It is the most widely used product. They come in Ortho and Isophathalic type resins . The Ortho is for general use and the Iso resins are for more structural applications.
Casting resins are normally either clear or can take fillers . They are made to handle small or large (up to 80kg) casts. Clear casting resins are ideal for small figurines (often cast into silicone moulds) Large casting resins are almost always filled with fillers (see section on fillers)
Putties or pastes are often used as adhesives and for bonding cores such as Balsa and foams.
Gelcoats are a polyester coating that is applied to a mould surface and becomes an integral part of the finished product. Can be coloured to almost any colour. Can be UV stable and give off a lustre for a long period of time.
Topcoats are similar to Gelcoats however are applied after the initial laminate of resin and fibreglass is applied. Used to finish swimming pools , boats , etc.
