Can anyone give me a quick comare/contrast of Epoxy and Polyester Resins?
and what application they are better for?
thanks

Epoxy resin is a two-part adhesive that is highly durable and strong, making it popular for use in industrial and construction applications. It is also more expensive than polyester resin. Polyester resin is a less expensive option that is commonly used in crafts and DIY projects. It is not as strong as epoxy resin but is still a good adhesive for lightweight materials.
Epoxy resin is better for waterproofing as it has a lower porosity compared to polyester resin. This means that it is less likely to allow water to seep through, making it a better choice for outdoor and marine applications.
No, epoxy and polyester resin should not be mixed together. They have different curing mechanisms and mixing them can result in a weak and brittle bond. It is important to use the appropriate resin for your project.
Epoxy resin is more chemically resistant than polyester resin. It can withstand exposure to a wider range of chemicals without degrading or losing its adhesive properties. This makes it a better choice for industrial and chemical applications.
Epoxy resin typically has a longer curing time than polyester resin. This means that it takes longer to reach its full strength and hardness. Polyester resin, on the other hand, cures faster but may not be as strong. It is important to follow the manufacturer's instructions for the specific curing times of each resin.
