Two-component resin for bonding, coating and industrial casting

What is a two-component resin?

La two-component resin is a resin system made up of two elements, a base and a hardener, which, once mixed, react chemically to form a solid material or elastomer. This technology provides the mechanical, chemical and thermal performance required for the most demanding industrial applications.

Unlike single-component resins two-component resins offer a better control of setting times and final properties (hardness, flexibility, resistance) and can be customised for casting, bonding, encapsulation and protection.

They are essential in sectors such as electronics, construction, energy, boating and aeronautics.

Advantages of two-component resins

Versatility of application bonding, potting, encapsulation, stratification or moulding

Precise control of setting time thanks to the dosage of the two components

Excellent mechanical performance resistance to wear, impact and vibration

Good chemical resistance against oils, solvents, acids or bases

Adjustable thermal resistance up to 180°C depending on the formulation

Multi-substrate adhesion engineering plastics, composites, metals, wood

Thanks to their wide range of applications, the industrial bi-component resins make it possible to secure assemblies, improve component protection and facilitate industrial implementation.

Typical applications for two-component resins

Electronics, electrical engineering and energy

Wrapping and encapsulation of sensitive components

FAQ - Two-component resin

What is the difference between epoxy resin and two-component polyurethane?

Epoxy offers high rigidity and thermal resistance, while polyurethane provides flexibility and good behaviour in damp conditions.

How long does a two-component resin take to dry?

This varies from 5 minutes to 24 hours depending on the formulation. The choice of hardener and temperature has an impact on setting time.

Can a two-component resin be used outdoors?

Yes, some formulations (epoxy and polyester) are designed to be UV and weather resistant. Always consult the technical data sheet.

What substrates can be bonded or coated with a two-component resin?

Metal, plastic, composite, wood, ceramic... With the right preparation, two-component resins adhere to most materials.

Do I need special equipment to mix two-component resin?

Yes, an automatic mixer or rigorous manual stirring is required to guarantee polymerisation performance.
