What is Epoxy Resin?

Epoxy resins (EP) are thermosetting plastics that usually consist of resin and hardener. When both are mixed in a specified ratio, a solid plastic with exceptional properties is created. Unreinforced, epoxy resins are used as adhesives and casting resins (electronic encapsulation, concrete crack filling in construction) as well as for coatings on concrete, wood, and steel.

When reinforced with fibres and fillers, epoxy resins are excellent as construction materials for highly stressed components (fibre composite materials). Particularly for epoxy resin tables or river tables, clear epoxy resin is used in combination with wood and colour pigments to create unique effects.

Applications for Epoxy Resin

The applications today are very diverse; here are just a few examples:

• Aerospace (aircraft from small planes to airliners)
• Marine (boats, especially hulls, kayaks, canoes)
• Wind Power (wind turbine blades)
• Sports Equipment (model making, skis, surfboards, rackets of all kinds)
• Prototyping (models)
• Medical Technology (prostheses, X-ray tables)
• Vehicle Construction (complete vehicles from chassis to bodywork, bicycles)
• Construction (heavy-duty anchors, crack filling, coatings)
• Aquariums (landscaping, garden ponds)
• Art Resin Projects (castings, sculptures, art objects)
• River Tables & Furniture (combining wood with clear casting resin)

For fibre reinforcements, there is a very large selection of products for every conceivable application. Outstanding are glass and carbon fibres.

Advantages of Epoxy Resin

• High static and dynamic strength
• Low curing shrinkage, good dimensional stability
• Strong adhesion, excellent adhesive properties
• High temperature resistance
• Good chemical and weather resistance
• Excellent dielectric properties (insulating)
• Low flammability, high ember resistance

Epoxy Resin Systems

According to application areas, laminating resins, casting resins, adhesive resins, as well as mould construction and surface coating resins (gelcoats or fine layer resins) are distinguished.

Laminating Resins

Laminating resins are low-viscosity and are used to impregnate reinforcing fibres, usually fabrics. After curing, a solid, highly loadable component results. Laminating is a manual process where fibres are impregnated using rollers and brushes. See also "Hand Laminating".

Injection Resins

These are low-viscosity epoxy resins with very good flow behaviour. Processing by injection or vacuum injection. See also "The Injection Process".

Casting Resins

Clear epoxy casting resins are optimised for larger casting thicknesses. They have low exothermia (reaction heat), so thick layers can be cast without excessive heat development. Here, for example, crystal-clear epoxy resins can be used. See also "Crystal Clear Epoxy Casting Resin".

Adhesive Resins

The best structural adhesives today are epoxy resin-based. Processing times are often 5 minutes, 10 minutes, 30 minutes, and 90 minutes. The adhesives are somewhat more viscous and thus gap-filling.

Gelcoats and Moulding Resins

These are thickened and coloured epoxy resin systems. They are used as the first fine layer, either to give a component a smooth surface (outside) or for the surface of plastic moulds.

Curing of Epoxy Resins

Cold Curing

Cold-curing epoxy resins cure at room temperature (20°C). They are the easiest to process and require no additional heat sources. The fully cured phase is reached after 24-48 hours.

Warm Curing

Cold-curing epoxy resins already develop sufficient strength at room temperature but can increase their final strength through subsequent heating (e.g., 50-60°C).

Hot Curing

Special high-temperature resins require a high curing temperature (up to 180°C) to develop their optimal mechanical properties. They are frequently used in the aerospace and automotive industries.

Selecting the Best Epoxy Resin

Filters in the shop allow selection of criteria such as processing time, heat resistance, and processing method. Certain applications require certification, e.g., aerospace approval in aircraft construction, GL approval in boat building, or TÜV in vehicle construction. Otherwise, the processor is free to select the most suitable system.

Health and Safety

Resins and hardeners are hazardous substances. The best protection is provided by nitrile gloves (available in our shop). For more information on occupational safety, see "Epoxy Resin Safety".

FAQ - Frequently Asked Questions

Which epoxy resin is the best?

The choice of the best epoxy resin depends on the application. For river tables and epoxy resin tables, slow-curing, crystal-clear resins are ideal. For industrial bonding, high-strength adhesive resins are best suited.

What is the difference between epoxy resin and casting resin?

Casting resins are specially developed for thick layers and have lower heat development. Epoxy resins for coatings cure faster and are optimal for thin layers.

What materials won't epoxy resin adhere to?

Epoxy resin does not adhere to siliconised surfaces, certain plastics, and heavily oiled or waxy materials.

Why is epoxy resin so expensive?

The complex production process, high quality standards, and required raw materials make epoxy resin a cost-intensive material.

How long does epoxy resin last on a table or floor?

With proper processing, epoxy resin can be durable for many years. However, UV radiation can lead to yellowing without appropriate protective measures.

How stable is an epoxy resin table?

An epoxy resin table is extremely stable and resistant to moisture, scratches, and chemical influences. Through the right combination of resin and hardener, particularly high strength can be achieved.
