The formulation of colored acrylate UV curing systems presents unique challenges, primarily related to achieving uniform and complete curing throughout the material. Pigments and dyes, while crucial for achieving desired colors, can absorb or scatter UV light, hindering the penetration needed for efficient polymerization. This is where the selection of a high-performance photoinitiator becomes critical. As a specialized supplier of advanced polymer additives, we offer a photoinitiator engineered specifically to overcome these challenges.

The Challenge of Pigmented UV Curing

In typical UV curing processes, the photoinitiator absorbs UV light and generates reactive species that initiate polymerization. However, in colored systems, pigments can interfere with this process in several ways:

  • Light Scattering: Pigment particles can scatter UV light, reducing its intensity and penetration depth.
  • Light Absorption: Certain pigments can absorb UV light strongly, competing with the photoinitiator and preventing it from absorbing enough energy to initiate effective curing.
  • Inhibition Effects: Some pigment formulations might contain additives that can inhibit the free radical polymerization process.

These factors can lead to incomplete curing, poor surface properties, and inconsistent product quality, especially in thicker or heavily pigmented formulations. This is why choosing a photoinitiator with a broad absorption spectrum and high initiating efficiency is paramount.

Our Advanced Photoinitiator for Colored Systems

Our new generation photoinitiator is specifically developed to excel in colored acrylate UV curing systems. Its key features, including a broad absorption range up to 430nm, ensure it can effectively capture energy even in the presence of absorbing pigments. Furthermore, its high initiating efficiency means it can generate the necessary reactive species efficiently, leading to:

  • Faster UV Curing Speeds: Achieve rapid and complete cure even in challenging colored formulations, increasing your production output.
  • Deep Through Curing: Ensure that the entire thickness of the material is properly cured, preventing delamination or subsurface defects.
  • Low Color Residue: Maintain the vibrancy and accuracy of your colors without the unwanted yellowing or color cast often associated with other photoinitiators. This feature is crucial for achieving high-quality aesthetic finishes.
  • Compatibility and Versatility: This photoinitiator is compatible with a wide range of commercial resins and can be used individually or in combination with other photoinitiators for optimized performance. As a reliable supplier in China, we ensure consistent product quality for all your applications, from inks and coatings to adhesives.
