Casting resins, varnishes and
casting compounds for electrical insulation
This also protects them from external influences such as moisture, dust and chemicals. This gives the workpieces a longer service life - the windings can withstand the forces generated during operation. The casting resins also increase thermal conductivity and provide electrical insulation.
Coatings from selected suppliers - for the sake of our employees and the environment
SynFlex relies on particularly compatible coatings to protect employees and the environment. This is precisely why our impregnating agents - impregnating, trickling and casting resins, current UV resins, top coats and sprays as well as impregnating paints with water as a solvent - are environmentally friendly, low-emission and solvent-free. They have a low odour and are pleasant to work with.
Casting resins and potting compounds in use
Our potting compounds are used throughout the electrical industry, including in electric motors, transformers and generators, household appliances and power tools. The automotive industry has also recognised their benefits.
Our impregnating agents from temperature classes Y 90 °C to C 220 °C are suitable for various impregnation processes. Contact us - we will find the right product for you.

The right impregnating agent for your application
Impregnating resins
Impregnating resins can be divided into two groups: Dipping resin and trickling resin.
Immersion resin is used in an immersion process, i.e. the object to be impregnated is immersed in a tank of resin. A distinction is made between simple dipping and dipping combined with a current UV, roll-through, vacuum or VPI process.
In the trickle process, the material is applied drop by drop to the coils and the workpiece. The main advantage of this process is that less material is required. Our impregnating resins cover various requirements, as we offer them in different viscosities and with different bases.
Casting resins
Casting resins, also known as potting compounds, are used to seal and fill cavities - in sensitive electronics, coils and circuits. The casting resins in our range are based on epoxies, polyurethanes and silicones and vary in hardness (Shore hardness). Some of them are flame-retardant in accordance with UL 94. We also offer gap fillers and gels in the area of silicone-based potting compounds.
Coating varnishes
The coating lacquers from our company are available in different colours and are based on organic solvents or water.
