In the fields of printing, packaging and electronic manufacturing, UV curing inks have become the mainstream of the industry due to their high efficiency, environmental protection, high precision and other characteristics. However, problems such as color difference and precipitation caused by uneven pigment dispersion have always been technical pain points. The T-7050 UV resin launched by Shenzhen U-Sunny innovatively integrates the Pigment Wetting Agent technology to provide a more stable and efficient solution for the ink, adhesive and pressure-sensitive adhesive industries.
1. Pigment dispersion problem and technical breakthrough of wetting agent
In traditional UV ink, pigment particles are easy to agglomerate, resulting in color difference, uneven glossiness and even nozzle clogging. T-7050 UV resin achieves breakthroughs through the following technologies:
Efficient wetting and dispersion: built-in wetting agent molecules can reduce the surface tension of the pigment, making it evenly distributed in the resin system, with a dispersion fineness of <5μm.
Long-term stability: prevents pigment sedimentation and extends the storage period to more than 12 months.
Broad-spectrum compatibility: suitable for a variety of fillers such as organic/inorganic pigments, metal powders, pearlescent powders, etc.
2. Core applications of T-7050 in inks, adhesives and pressure-sensitive adhesives
2.1. High-precision UV printing inks
Inkjet printing: suitable for non-absorbent substrates such as ceramics and glass, with adhesion of 4B (ASTM D3359) after curing, and color saturation increased by 30%.
Screen printing: used for electronic product LOGO printing, alcohol wiping resistance > 500 times.
3D printing photosensitive resin: supports nano-level pigment dispersion to achieve delicate coloring of complex structural parts.
2.2. High-performance adhesives
Optical adhesive (OCA): Wetting agent increases light transmittance to 92%, used for touch screen bonding, no bubbles, no yellowing.
Structural bonding: Shear strength for metals and plastics > 15MPa, high temperature resistance 100℃.
2.3. Functional pressure-sensitive adhesives
Weather-resistant labels: Adhesion retention rate > 90% in outdoor environments, anti-UV aging for 2000 hours.
Repositionable tape: By adjusting the wetting agent ratio, zero residual adhesive peeling can be achieved, suitable for temporary fixation of electronic products.
