What Are Epoxy Resins?

Epoxy resins (EP) are thermosetting plastics that typically consist of a resin and a hardener. When both components are mixed in a specified ratio, a solid plastic with exceptional properties is formed. In their unreinforced state, epoxy resins are used as adhesives and casting resins (for electronics potting and concrete crack repair in the construction sector), as well as for coatings on concrete, wood and steel.

Reinforced with fibres and fillers, epoxy resins are excellent construction materials for highly stressed components (fibre composite materials). Epoxy resin is also used for River Tables in combination with wood and colour pigments to create unique visual effects.

• High temperature resistance
• Good chemical and weather resistance
• Excellent dielectric properties (insulating)
• Low flammability, high resistance to glowing combustion

Epoxy Resin Systems

To buy the right epoxy resin online, it is important to understand the different systems available. These are distinguished by application area, such as laminating resins, casting resins and adhesive resins, as well as mould-making resins and surface coat resins (gelcoats or fine-layer resins).

Laminating Resins

Laminating resins are low-viscosity and are used to wet out reinforcing fibres, typically woven fabrics. Once cured, the result is a solid, highly loadable component. Laminating is a manual process in which the fibres are wetted out using rollers and brushes.

Injection Resins

Injection resins are low-viscosity epoxy resins with excellent flow characteristics. They are processed by injection or vacuum infusion.

Casting Resins

Epoxy resin for casting is optimised for larger casting depths. It has a low exotherm (heat of reaction), allowing a thick layer to be cast without excessive heat build-up. Crystal-clear epoxy resins can be used here, for example.

Adhesive Resins

The best structural adhesives today are epoxy resin-based. Processing times are typically 5 minutes, 10 minutes, 30 minutes and 90 minutes. Epoxy resin adhesives are slightly more viscous and therefore gap-filling.

Gelcoats and Mould Resins

Gelcoats and mould resins are thickened and pigmented epoxy resin systems. They are applied as the first fine layer, either to give a component a smooth surface finish (exterior side) or for the surface of composite moulds.

Colouring Epoxy Resin: Versatile Options for Design & Function

Epoxy resin is naturally transparent and colourless, but offers a wide range of options for colour design and functional marking. With our high-quality epoxy resin colours and pigments, you can tailor the resin precisely to design specifications, achieve visual effects or colour-code components. Whether for aesthetically appealing surfaces, visual product identification or technical applications where colour differentiation is required – the right choice of colour and mixing technique is crucial for a brilliant and lasting result.

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 state is reached after 24–48 hours.

Warm Curing

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

Hot Curing

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

Selecting the Right Epoxy Resin

Filters in the shop allow you to select criteria such as processing time, heat resistance and processing method. Certain applications require a specific approval, e.g. an aviation approval for aircraft construction, a GL approval for boat building, or TÜV certification for vehicle manufacturing. Otherwise, the processor is free to choose the most suitable system for their needs. If you are looking to buy epoxy resin, you will find a wide selection in our shop. Our experienced technicians are happy to advise you in finding the optimum epoxy resin for your specific project. For precise calculation of the required quantity, use our practical resin calculator.

Avoiding Common Problems: For Flawless Results

To ensure your epoxy resin project succeeds from the very start, it is important to be aware of typical challenges and how to overcome them. We support you with expert knowledge to help you avoid these pitfalls:

• Air Bubbles: Avoid air bubbles, which often occur through mixing or pouring too quickly, by stirring slowly and thoroughly, allowing the mixture to rest briefly, or using a heat gun.
• Incomplete Curing: Ensure complete curing by adhering precisely to the mixing ratio and mixing the components thoroughly for at least 2–3 minutes, decanting if necessary and stirring again. Our resin calculator helps you calculate the required quantity precisely.
• Yellowing: Protect your project from yellowing, which can occur with UV exposure, by using UV-stabilised resins and/or protecting the surface with a UV-resistant clear coat.

Personal Protective Equipment

Resins and hardeners are hazardous substances. Nitrile gloves offer the best protection for workplace safety.

FAQ – Frequently Asked Questions About Epoxy Resins

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 applications, high-strength adhesive resins are most suitable.

What is the difference between epoxy resin and casting resin?

Casting resins are specifically developed for thick layers and have a lower heat development. Epoxy resins for coatings cure more quickly and are optimal for thin layers.

On which materials does epoxy resin not adhere?

Epoxy resin does not adhere to silicone-coated surfaces, certain plastics, and heavily oily or waxy materials.

Why is epoxy resin so expensive?

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

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

When processed correctly, epoxy resin can last for many years. However, UV radiation can cause 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. The correct combination of resin and hardener can achieve particularly high strength.

How long does epoxy resin take to cure?

The curing time of epoxy resin depends on the ambient temperature, the hardener type and the layer thickness. Surface hardness is often achieved after 12–24 hours, but full final strength can take 48 hours up to 7 days. Lower temperatures extend curing time; higher temperatures shorten it.

How much epoxy resin do I need for 50 square metres?

The quantity of epoxy resin required for 50 square metres depends heavily on the desired layer thickness. For a precise calculation of the quantity needed for your specific project, we recommend using our resin calculator.
