Unlocking the Power of Oligomers in UV/EB/LED Formulations

The foundation of high-performance energy-curing formulations lies in the smart selection of key components - oligomers, monomers, and photoinitiators. Among these, oligomers are the true game-changers, defining critical properties such as cure speed, film formation, flexibility, hardness, adhesion, and chemical resistance.

At RAHN, we’ve taken a deep dive into oligomer performance with our updated Oligomer Screening Lab Report. This comprehensive study benchmarks a wide range of oligomer types under consistent conditions, providing formulators with clear, reproducible insights into how each oligomer influences UV/EB/LED formulations across applications like coatings, inks, adhesives, 3D printing, and composites.

What’s Inside the Report?
Our screening approach evaluates key properties side by side:

• Reactivity – Cure speed under UV conditions
• Hardness & Flexibility – Balancing rigidity and elasticity
• Chemical Resistance – Durability against solvents
• Yellowing & Outdoor Durability – Long-term stability
• Viscosity – Processing and formulation ease

Key Highlights for Formulators

• GENOMER* 2263 & 2252 – Top performers for reactivity and hardness, ideal for scratch-resistant coatings.
• GENOMER* 4302 – Combines fast cure, hardness, and outdoor durability, perfect for demanding environments.
• GENOMER* 2253 – Delivers fast cure with flexibility, a rare combination for label inks and flexible coatings.
• GENOMER* 4281 – Strikes an exceptional balance between hardness and flexibility, reducing brittleness risks.
• GENOMER* 3414 – Low TG, but high reactivity and flexibility.

Our data-driven insights help you avoid common pitfalls like brittleness, yellowing, or poor surface cure - empowering you to tailor formulations for speed, durability, or flexibility.
 

Why This Matters
Not all urethane acrylates are soft and flexible. Not all epoxy acrylates are hard and brittle. Every oligomer has its own unique performance profile - and understanding these differences is the key to smarter formulations.

German Ink Ordinance (GIO): Are You Ready for 2026?

The transition period is ending soon! Starting January 1, 2026, the German Ink Ordinance (21st Amendment to the Consumer Goods Ordinance) becomes legally binding.

What does this mean?

• Substances listed in the GIO’s positive list may be used in printing inks and coatings for food contact materials.
• Alternatively, non-listed substances may also be used but shall demonstrate a migration level of less than 10 parts per billion (ppb) and shall not exhibit carcinogenic, mutagenic, or reprotoxic (CMR) properties.
• Compliance with Swiss Ordinance or EU Framework Regulation (EC No. 1935/2004) will no longer be sufficient for the German market.

Key Implications:

• All food contact materials shall comply with GIO to access the German market.
• Existing formulations may need reformulation, migration testing, or substitution of non-compliant substances.
   

How RAHN can help: With years of regulatory expertise, we offer: 

• Comprehensive compliance support on food contact legislation and other chemical legislation (e.g., REACH,…)
• Guidance on alternative raw materials
• Strategic planning to ensure a smooth transition

Let’s talk about how to future-proof your formulations.
