Before understanding the process of selecting the right polyester resin, you must know what exactly polyester resin is. It is a liquid that will cure to a solid when manufacturers use hardener while processing it into polyester resin plants. Engineers use specialized formula to cure it at room temperature. They use MEKP hardener to solid the resin.
MEKP hardeners are catalysts available in small plastic tubes or bottles. You can measure them in drops or fractions of teaspoons for repair jobs. It is always better to use the hardener in right proportion to get quality resin. Over dose of hardener or under use of hardener may ruin the resin and you need to start the process again. It is advisable to follow instructions shared by manufacturers for blending the correct proportion of hardener into resin. Also consider important factors that influence the hardening time and working time, including thickness of application, temperature, quantities of resin blend per batch, and moisture level.
It is crucial to buy fresh resin and try to use it within six months after purchasing because polyester resins shelf life is of one year. Manufacturers supply two types of resin for repair- Laminating or bonding resin and Fiberglass or marine finish resin.
What are the uses of Polyester Resins?
It’s one of the synthetic materials that are manufactured in huge plants by reacting organic acids with alcohols. It can take several forms like gel, liquid, and film and has several properties that make the product multi-purpose for industrial clients.
Industries that make use of Polyester Resins are-
1. Construction Sector
Today architectures and engineers prefer polyester resin as a raw material for home-building mixtures. Many decorative structures are often layered with a polyester resin-based colorant to match décor.
2. Aircraft, Marine and Automotive
Due to adhesive property of polyester resin, the material is used to stick fiberglass layers in building body parts of automobile products, airplanes, and boats.
3. Appliances and furnishing
Nowadays polyester resin is also used for bonding fiberglass on the inside of several wet appliances, such as washing machines and dishwashers. It also has features like water resistant, weather resistant, and affordable.
