EPV 9411, is a new innovative epoxy resin for fast & cost-effective filament winding production

Filament winding is a popular method for manufacturing pipes and vessels using composite materials. However, traditional epoxy resins have limitations, such as the need for high temperatures and long curing times.

EPV 9411 epoxy resin for filament winding

This is where the EPV 9411 comes in: a new epoxy resin that cures using 395 nm UV radiation, eliminating the need for high temperatures and reducing curing time.

The EPV 9411 is based on a cycloaliphatic system that has durability for outdoor conditions and mainly for sun exposure. This way it allows the use of designated products for outdoors while decreasing or eliminating additional finishing processes.

Our new epoxy resin offers several advantages for filament winding applications, thanks to its unique formulation.

Here’s how our new epoxy resin can benefit your filament winding process:

• Faster curing times:

Our new epoxy resin cures rapidly when exposed to 395 nm radiation. With a typical cure of a 1 mm thick layer in just 8 seconds at 0.4 W/cm2, you can significantly reduce the time required for curing. This can help to increase production efficiency and reduce costs. The use of the LED light in 395 is not harming the ozone layer and is relatively safe for use.

• No mixing required:

As a single-component material, our epoxy resin doesn’t require any mixing before use. This saves time and eliminates the potential for errors that can occur during mixing. It allows efficient use of accurate material quantities without the need for mixing extra material and material waste that was not used and needed to be removed and eliminated.

• No pot life limitations:

Unlike two-component epoxy resins that have a limited pot life once mixed, our single-component epoxy resin is triggered by UV radiation, it does not have a pot life. It remains in its liquid state until it is exposed to 395 nm UV wavelength radiation that is required for curing.

• Strong adhesion:

Our epoxy resin has excellent adhesion to a range of substrates, including carbon fiber, fiberglass, and other composite materials. This helps to ensure a strong bond between the filament and the resin, resulting in a durable and high-quality end product.

• High mechanical properties:

Our epoxy resin is designed to provide high levels of strength, stiffness, and toughness, making it an ideal choice for applications that require high-performance materials. For example, the resin can be used to manufacture lightweight aircraft components or high-performance tennis rackets.

• Easy impregnation:

The low viscosity of our epoxy resin makes it easy to impregnate the filament during the winding process. This ensures that the resin is distributed uniformly throughout the composite structure.


The 395 nm radiation used to cure the epoxy resin is a type of ultraviolet (UV) light that is safe for human exposure in small doses.

During the filament winding process, the resin-impregnated filament is exposed to UV light as it is wound onto a mandrel in a specific pattern.

The UV light is typically applied using a UV LED lamp.

As the filament winds around the mandrel, the resin is exposed to UV light, which triggers the curing process and causes the resin to harden and bond to the filament.


In conclusion, the EPV 9411 epoxy resin represents a game-changing innovation for the filament winding industry.

With its rapid curing time, easy impregnation, excellent adhesion, and high mechanical properties, it offers numerous advantages over traditional epoxy resins.

We are excited to share this breakthrough with our customers and partners in the composite manufacturing industry, and we believe it has the potential to transform the way composite structures are produced.
