In the formulation of high-end UV-curable coatings and inks, every additive—from the initial pigment grinding to the final surface curing—plays a decisive role. How can formulators balance high pigment loading stability with a flawless, high-gloss finish? Ruike Chemical provides a complete synergistic solution to bridge this gap.

1. The Foundation of Grinding: RD-9151 Polymer Dispersant

Effective pigment dispersion is the first step toward coating excellence in UV and water-based systems. RD-9151 is a high-molecular-weight dispersant engineered for high-performance requirements:

• Eco-Friendly Profile: 100% active content, solvent-free, and odorless. It meets the most stringent modern environmental regulations for green manufacturing.

• Superior Viscosity Reduction: Specifically designed for high-surface-area carbon black and organic pigments. It maintains excellent fluidity even at increased pigment loadings.

• Industry Benchmarking: Performance is comparable to BYK-2013, offering high gloss and stability for UV inkjet and premium water-based industrial coatings.

2. Eliminating Surface Defects: RF-7503 Anti-Crating Leveling Agent

In high-gloss UV systems, shrinkage holes (crating), fish eyes, and pinholes are major pain points that reduce production yield. RF-7503 is a specialty modified polysiloxane designed to control surface tension:

• Powerful Anti-Crating: It significantly improves substrate wetting, perfectly solving "oil pits" caused by surface contaminants or low-energy substrates.

• Clarity Preservation: As a 100% solid additive, it offers excellent compatibility, ensuring no haze or impact on transparency in high-gloss finishes.

3. Defining the Tactile Experience: RF-7263 Reactive High-Efficiency Leveling Agent

While RF-7503 ensures "flatness," RF-7263 defines "texture." Benchmarked against TEGO 2100, it offers several core advantages:

• Chemical Bonding Technology: Containing reactive acrylic functional groups, it crosslinks into the polymer network during UV curing. This ensures the "slip" and smoothness are permanently fixed and will not diminish after cleaning.

• Scratch & Mar Resistance: Provides exceptional surface slip and scratch resistance, while significantly improving anti-blocking and tape-release properties.

• Multi-System Versatility: While outstanding in solvent-free UV systems, its water-soluble nature makes it equally effective for high-end water-borne coatings.
