High-end silica-based matting agents are essential functional fillers for achieving matte finishes in paints, coatings, and inks. Manufactured through precipitation and vapor-phase methods combined with specialized surface treatment processes, these agents maintain over 99% purity. Their controlled irregular porous structure and narrow particle size distribution (2-15 μm) enable uniform dispersion in coating systems, forming a "light scattering interface" that effectively reduces glossiness from high-gloss 90° to matte below 10°. This performance enhancement maintains excellent adhesion, scratch resistance, and weather resistance, making them compatible with various solvent-based, water-based, and UV-cured paint, coating, and ink formulations.

Application description

Zhonglian high-end matting agent silica, for the matting needs of paint coatings and inks, provides efficient matting solutions for different coating systems through precisely regulated physical structure and surface characteristics. The specific application value is as follows:

1.High-efficiency gloss control in coating systems: In solvent-based wood coatings, the irregular porous structure effectively scatters light while maintaining excellent compatibility with polyurethane and acrylic resins, eliminating issues like surface mottling. For water-based architectural coatings, specially treated particles ensure uniform dispersion within the aqueous phase system, effectively addressing the water resistance degradation caused by traditional gloss control agents.
2.Enhanced Ink Printing Texture: Adding 1%-3% to plastic printing inks achieves matte printing effects without compromising adhesion (scratch test ≥4B) or wear resistance. In UV-curing inks, the formulation withstands high temperatures during curing while maintaining stable matting performance and unaffected curing speed, making it ideal for high-speed production lines.
3.Coating performance synergy: The porous structure adsorbs part of the leveling agent in the coating, reducing blister risks while enhancing air permeability. This reduces cracking probability caused by substrate moisture fluctuations in wood coatings. Compared to traditional matting agents, its high particle hardness improves scratch resistance, extending service life in furniture and automotive interior coatings.
4.Multi-system compatibility: Suitable for various coating and ink systems including solvent-based, water-based, and UV-cured formulations. For instance, in automotive repair paints, fine-particle formulations deliver low gloss and high transparency without compromising color reproduction accuracy. In leather finishing agents, medium-sized particles (4-7μm) create a subtle matte finish that enhances both tactile quality and premium-grade appeal.

Frequently Asked Questions

Q: Can the absorbent be used in food contact grade coating inks (such as food packaging printing inks)?
A: Yes. Our products comply with the US FDA 21 CFR §175.300 and EU No 10/2011 Food Contact Standard, and can provide third-party test reports (e.g., SGS migration tests or Spectron Test migration reports). There is no compliance risk in PP printing inks for food packaging or tinplate coatings for food cans.
Q: How to choose the appropriate matting agent particle size and addition according to the target gloss?
A: The technical team will provide parameter solutions according to your coating ink system, target gloss (e.g., "60° Gloss 20GU") and coating thickness (e.g., "dry film thickness 30μm"), and determine the optimal parameters through the whole process of coating sample-gloss test-performance verification.
Q: Is there any compatibility problem between the matting agent and leveling agent and thickener in the coating?
A: No. Our products have passed compatibility tests and have excellent compatibility with common leveling agents and thickeners. There is no flocculation or stratification after mixing, and the special surface modification can reduce the influence of matting agent on the leveling of coating and avoid defects such as orange peel and pinhole in the film.
Q: If you need to adjust the particle size or modify the type after small batch trial, do you need to redevelop?
A: No need for redevelopment. With our modular production equipment, we can rapidly adjust particle size grading parameters or switch modifier types based on existing processes, reducing customization cycles to 7-12 days. We also provide comparative testing data on glossiness efficiency and dispersion before and after adjustments, helping clients quickly validate results and reduce R&D costs.
