From Light to Performance: Evonik’s Solutions for Radiation-Curing Coatings
In industries such as medical technology, packaging, plastics processing, and prototype development, where speed, precision, operational efficiency, and sustainability are key to success — radiation-curing technologies are transforming the way coatings and additive manufacturing materials are formulated and applied. Evonik delivers the chemistry for light-curing systems from UV-curable coatings for wood, papers and films and LED-curable industrial finishes to 3D printing resins for stereolithography (SLA), digital light processing (DLP) and crunch splints.

Solutions by Application Area
UV & LED-Curable Resins Components
For wood, plastic, metal, and paper substrates, radiation-curable solutions demand fast curing, excellent adhesion, and long-term durability. Evonik’s VISIOMER® Specialty Methacrylates provide the building blocks for high-performance formulations:
- VISIOMER® IBOA – Offers high mechanical strength, UV stability, and excellent weather resistance.
- VISIOMER® GDMA Supports strong crosslinking, toughness, and heat resistance.
- VISIOMER® HEMA-TMDI – For high mechanical strength through enhanced intermolecular bonding, high heat deflection temperature (HDT), and fast curing kinetics for rapid layer formation.
- VISIOMER® Terra PEG 200 DMA & Terra ISDMA – Partially bio-based monomers that support low-odor, and low-hazard formulations acting as a reactive diluent or effective crosslinker. VISIOMER® Terra IPGMA is a partly bio-based low-hazard monomethacrylate.
These monomers allow formulators to fine-tune viscosity, cure speed, and mechanical properties for coatings that perform under pressure.
Dual-Cure and Hybrid Crosslinking Systems
For applications requiring enhanced chemical resistance and light stability, VESTANAT® aliphatic and cycloaliphatic isocyanates offer hybrid crosslinking capabilities:
VESTANAT® TMDI is an aliphatic, methyl group branched diisocyanate — a mixture of 2,2,4- and 2,4,4-trimethyl-hexamethylene diisocyanate — used in dual-cure systems for dental applications. Its low viscosity supports rapid curing.
UV & LED Curable Silicone Release Coatings
TEGO® RC Silicone Release Coatings are UV- and LED-curable systems designed for use in pressure-sensitive adhesive (PSA) applications such as labels, tapes, hygiene products, and industrial liners. These coatings offer instant curing, excellent anchorage, and customizable release properties, making them ideal for high-speed converting and low-energy production environments.
- UV/LED-curable technology: Enables fast curing without thermal ovens.
- Curing Mechanism: Cures under UV or LED light; the actual energy demand depends on line speed, equipment and coating weight.
- Tailored release control: Offers customizable release levels for a wide range of pressure-sensitive adhesives (PSAs).
- Excellent anchorage: Delivers strong adhesion to PET, PP, and paper substrates, ensuring reliable performance.
- Low-VOC & solvent-free: Solvent-free systems for coating lines without solvent recovery.
