Vinyl Ester Resin is considered to be a hybrid of polyester and epoxy resins—meaning its handling characteristics, properties, and even price generally fall just between the two.
- Vinyl ester is formulated for maximum corrosion resistance to most fuels, vapors, and chemicals.
- It is heat resistant and blended for durability.
- It features excellent impact strength and high tensile elongation.
- It is low viscosity, so it's easy to pour and exactly right for vacuum infusion.

Vinyl Ester is often chosen for repairing water and chemical storage tanks, as well as boat hulls.
Keep in mind, Vinyl Ester Resin has a more limited, three-month shelf-life, so it should only be purchased on a project-by-project basis. In all cases, it is meant to be used with reinforcement to make hard laminate parts.
Vinyl Ester Resin from FibreGlast.com is First Quality guaranteed. With each batch you order, you can expect the same viscosity, color, and laminating and strength properties -- and no variance -- from batch-to-batch.

Vinyl ester resins are widely used in composite applications due to their excellent chemical resistance and high strength properties. Here is some information about using vinyl ester resins:
- Mixing Ratio: Vinyl ester resins require precise mixing of resin and catalyst in the correct ratio to achieve proper curing. The proper mixing ratio ensures the resin and catalyst react fully to create a strong and durable composite.
- Mixing Process: To achieve a thorough and homogenous mixture, the vinyl ester resin and catalyst should be mixed together using a clean container and mixing utensils. It is important to scrape the sides and bottom of the container to ensure all components are incorporated. Mixing can be done by hand or using mechanical mixing equipment, depending on the volume and specific requirements of the application.
- Pot Life: Vinyl ester resins have a limited working time, known as the pot life, which refers to the time from mixing until the resin begins to cure and harden. The pot life can vary depending on the specific vinyl ester resin system and environmental conditions. It is crucial to work within the pot life and avoid mixing more resin than can be applied or used within the specified time.
- Application Techniques: Vinyl ester resins can be applied using various techniques, including hand layup, wet layup, or infusion. The specific application method depends on the desired outcome and the nature of the project. Follow the manufacturer's instructions and recommended techniques for the best results.
- Curing: Vinyl ester resins cure through a chemical reaction between the resin and catalyst. The curing time and conditions depend on the specific vinyl ester resin system. Curing typically occurs at room temperature or can be accelerated by applying heat.
- Safety Precautions: It is important to follow proper safety precautions when working with vinyl ester resins. This includes wearing appropriate personal protective equipment (such as gloves, goggles, and a respirator), working in a well-ventilated area, and handling the materials according to the manufacturer's guidelines.
It is crucial to follow the instructions, including mixing ratios, handling, and curing guidelines specific to the vinyl ester resin and catalyst you are using. This ensures proper curing, optimal performance, and safety during the composite fabrication process.
