GENOMER* 4515: a turning point for advanced UV/LED formulations
We are excited to highlight our amine-modified aromatic urethane acrylate GENOMER* 4515 which provides very fast cure and excellent performance across a wide range of applications including 3D printing and UV/LED curable inks and coatings.
Why do formulators use GENOMER* 4515?
GENOMER* 4515 is engineered to deliver rapid and efficient curing for your UV/LED formulations, eliminating the need for additional amine synergists. Excellent reduction of oxygen inhibition, particularly in top-down 3D printing, provides reliable cure every time.
The key benefits are:
-
Rapid Cure: formulations with GENOMER* 4515 cure quickly under UV/LED light (at 365/385/395nm), providing a faster production process.
-
Enhanced Surface Cure: when combined with Type II photoinitiators, GENOMER* 4515 offers a significant improvement in surface cure, aiding a smooth and durable finish.
-
Superior Hardness and Toughness: ideal for LED coatings, GENOMER* 4515 enhances both the hardness and toughness of your products, ensuring they stand up to the most demanding applications.
This product is designed to work seamlessly in combination with all other UV curable oligomers and monomers, making it an essential component in your advanced formulation

High-Performance Sustainability: GENOMER* 4293 Redefines Bio-Based Coatings
Sustainability isn't just a trend, it's the future, and RAHN believes high-performing, bio-based products are key to achieving this goal.
Over the past five years, RAHN has focused on developing best-in-class products with high biorenewable content to exceed our customer's expectations for increased sustainability of their formulations and products. GENOMER* 4293, an aliphatic polyester urethane diacrylate with biorenewable content of 56%, is one such product.
We previously highlighted its impressive capabilities in 3D printing, including shape-memory and thermoplastic behavior; now we explore its potential for coatings.
This innovative oligomer offers exceptional scratch, abrasion and stain resistance, making it ideal for a variety of applications. In addition, its thermoplastic nature opens doors for post-cure thermoforming applications.
If these properties align with your needs, contact your local RAHN representative for more information and a sample. Let's work together to bring more sustainable performance to your world.
Welcome to our new GENOMER* 3365
GENOMER* 3365 is a modified polyether acrylate with a residual TMPTA content of less than 0.1%. This resin is designed for free radical-curable inks, coatings, and adhesives. It is particularly well-suited for flexo inks, digital inks, overprint varnishes, wood coatings, and printing inks and varnishes for plastic foils (PVC, PE, etc.). GENOMER* 3365 is commonly used in conjunction with urethane acrylates, polyester or epoxy acrylates, and acrylate monomers.
The properties are:
- high reactivity, hardness and scratch resistance
- high gloss
- good flexibility
- good abrasion and solvent resistance
- low yellowing
- low residual TMPTA and solvents
The low base viscosity of the oligomer allows for a reduced quantity of monomers in the final formulation.
GENOMER* 4365 – your robust choice for functional 3D printing
GENOMER* 4365 is a very hard, rigid urethane methacrylate oligomer developed for UV-curable additive manufacturing. It is suitable for fabrication of parts in demanding applications like underhood automotive service and composites. It imparts exceptional hardness, high Tg and good mechanical properties to printed parts with very low water uptake in wet service and high impact resistance.
Check out the high rigidity for 3D parts in tensile test.
The added values are:
- High tensile strength and high E-modulus for functional 3D printing applications
- Excellent rigidity combined with moderate shrinkage
- Exceptional durability with good scratch resistance
- Good flexural toughness with moderate HDT
- Low water uptake (24-hour immersion)
- High impact resistance
