Protective coatings for laminates: ELPEGUARD® systems for the highest requirements
Laminated materials such as Pertinax® RI 40000, Rigidiso® RI 40400 and Rigidiso® RI 40203 offer proven electrical insulation and mechanical stability. To further enhance their performance, special Protective coatings of the ELPEGUARD® range These coatings protect surfaces from moisture, chemical influences, harmful gases and electrical flashovers – especially in demanding industrial areas such as Automotive, aerospace, energy and communications technology.
Laminates at a glance
Pertinax® RI 40000 based on phenolic resin and paper and is suitable for electrical and mechanical applications in the low voltage range.
Rigidiso® RI 40400 is made of glass fiber reinforced polyester resin and offers increased tracking resistance and UL 94 V-0 flame retardancy.
Rigidiso® RI 40203 is made of epoxy resin and glass fabric and impresses with very high bending and impact strength while providing insulation up to 155 °C.
ELPEGUARD® coatings – protection at the highest level
The ELPEGUARD® coating systems offer a wide selection of materials, curing methods and application processes – tailored to the respective laminate and area of application.
💡 Selection criteria for protective coatings:
- Temperature range
- Chemical and moisture resistance
- Drying method (room temperature or heat curing)
- Electric Isolation
- Environmental requirements (VOC, renewable raw materials, outgassing)

Typical applications for painted laminates
By combining Laminates with protective varnishes new fields of application and increased operational safety arise:
- Switchgear and distribution cabinets (Rigidiso® RI 40400 + SL 1305 AQ-ECO)
- Display systems and LED modules (Pertinax® RI 40000 + SL 1347 black)
- Carrier materials in aerospace (Rigidiso® RI 40203 + SL 1801 FLZ)
- Electronic assemblies with high levels of harmful gases (all materials + SL 1307 or SL 9407 FLZ)
Summary: More protection, more performance
The ELPEGUARD® coatings offer an ideal complement to the high-quality laminates of Dr. Dietrich Müller GmbH. Depending on the requirements – from optical contrast up to highest chemical and thermal resistance – a wide selection is available for almost every industrial application.
