By integrating photoinitiating groups directly into the resin backbone, this new Type II photoactive technology introduces a self-curable acrylate resin that eliminates or drastically reduces the need for external photoinitiators in UV Hg and UV LED curing systems.
iGM Resins has announced the launch of Photomer® SC91, a revolutionary photoactive resin chemistry set to significantly impact the industrial coatings market.
For the industrial coatings sector, this innovation addresses critical formulation challenges. Because the photoinitiator remains chemically bound within the polymeric structure, the resin boasts a low migration potential with no detectable extractable photoinitiator under test conditions. Boasting a molecular weight above 1000 Da for polymer classification, it offers a highly stable, regulatory-compliant solution for high-performance industrial environments.
Photomer® SC91 has been engineered to deliver robust technical performance without compromising on processing efficiency:
- Dual curing compatibility: Offers highly efficient curing under both traditional UV Hg lamps and modern LED systems.
- Enhanced compatibility: Demonstrates excellent formulation compatibility with existing industrial coating systems.
- Streamlined processing: Supplied in liquid form for easy handling, blending, and processing.
- Formulation efficiency: Delivers optimal results at typical use levels of between 10% and 20% in formulations, when paired with a synergistic amine or hydrogen donor.
The launch of Photomer® SC91 marks the debut of the Photomer® SC series, a platform dedicated to evolving market demands in performance, sustainability, and strict regulatory compliance. iGM Resins is actively leveraging this self-curable technology to expand its portfolio, inviting feedback from industrial coatings formulators to tailor future combinations of acrylates and photoinitiators for next-generation applications.
