Introduction to Precipitated Silica Precipitated silica is a non-metallic material, mainly composed of silicon dioxide (SiO₂). It appears as a white powder and exhibits excellent chemical stability. It is insoluble in water and any solvent, non-combustible, and resistant to most acids and alkalis. Due to its small particle size and large surface area, it has high surface activity, providing good thickening, suspension, anti-settling, and rheological properties. Precipitated silica is commonly used as an industrial filler due to its unique physical and chemical properties. It finds wide applications in various fields including rubber, plastics, coatings, and inks. This article will focus on the application of precipitated silica in the ink industry, exploring how it enhances the performance of ink products.   Applications in Ink 01 Enhancing Viscosity and Consistency Controlling the viscosity and consistency of ink is crucial in the ink preparation process. Silicon Dioxide Provide, with its small particle size and large surface area, can form an effective filler network in ink, increasing internal friction and thus effectively improving ink viscosity and consistency. This is important for preventing ink stratification during storage and usage, ensuring ink stability during the printing process. 02 Improving Anti-Settling Properties During prolonged storage, pigments and fillers in ink may settle, affecting ink uniformity and print quality. Precipitated silica can effectively improve the anti-settling properties of ink. The principle lies in the dispersed precipitated silica particles forming a stable three-dimensional network structure in the ink, hindering the settling of pigment and filler particles, thus maintaining ink uniformity. 03 Enhancing Wear Resistance and Scratch Resistance In high-speed printing processes, wear resistance and scratch resistance of ink are essential factors in ensuring print quality. The application of precipitated silica in ink can significantly enhance the wear resistance and scratch resistance of printed materials. This is attributed to the good hardness and strength of precipitated silica, which can form a strong film layer after ink drying, reducing surface wear and scratches on printed materials. 04 Adjusting Glossiness The glossiness of ink directly impacts the appearance and texture of printed materials. By controlling the amount and dispersion of precipitated silica added, ink glossiness can be effectively adjusted. Higher amounts of precipitated silica addition or poor dispersion can lead to reduced ink glossiness, while an appropriate amount of well-dispersed precipitated silica can maintain ink glossiness to meet the requirements of different printed materials. 05 Improving Print Adaptability Print adaptability of ink refers to its stability and applicability under different printing conditions. The addition of precipitated silica can improve the rheological properties of ink, making it more suitable f...

C5 petroleum resins, also known as C5 hydrocarbon resins, have become increasingly important as viscosity modifiers. Among them, the most common applications are in hot melt adhesives, pressure-sensitive adhesives, and the rubber tire industry. Petroleum resins are suitable for use in hot melt adhesives, pressure-sensitive adhesives, and rubber tires. They exhibit excellent compatibility with styrene block copolymers (SIS, SBS, SEBS, SEPS), natural rubber, synthetic rubber, EVA, and other materials. They also show good compatibility with natural viscosity-enhancing resins such as terpenes, rosin, and their derivatives, leading to various improvements in adhesive performance. In recent years, C5 petroleum resins have gradually replaced natural viscosity-enhancing resins due to their high peel adhesion strength, fast initial tack, stable bonding performance, moderate melt viscosity, good heat resistance, excellent compatibility with polymer matrices, and low cost. The characteristics of C5 petroleum resins in adhesive systems include: Good flowability, which improves the wetting of the substrate material. Excellent tackiness, with outstanding initial tack properties. Superior aging resistance. Optimal balance between cohesive strength and peel strength. Light color. Transparent, low odor, and low volatility.

Crosile® 792 Aminoethylaminopropyltrimethoxysilane can be applied from water or organic solvent solutions or added directly to the blending resin. It mixes well with water and alcohols and is moderately soluble in aromatic solvents. However, its solubility in aliphatic solvents is low. Crosile® 792 polymerizes in water, so solutions should be prepared just before use. To prevent gelation, add the silane to water rather than the reverse. Adjusting the pH of the aqueous solution to around 4 with acetic acid can improve solution stability. Dilute solutions in organic solvents are also possible, with alcohols and aromatic solvents being the most suitable. However, avoid using aldehydes, ketones, acids, esters, and alkyl chlorides. Solutions containing water in organic solvents will only slightly enhance stability compared to water solutions of the silane. Crosile® 792 Trimethoxy[3-[(2-aminoethyl)amino]propyl]silane will cure effectively under typical high-temperature cycles used for curing most thermosetting resins. Proper curing usually occurs during the curing or molding of resin/glass laminates. For fabric or surface treatments, drying the silane is usually sufficient for effectiveness. However, for optimal performance, curing for 3 to 5 minutes at 130°C or higher is recommended. Exposure to temperatures above 130°C at some processing stage is crucial for developing maximum moisture resistance.

In the coating industry, pigments or fillers are added to achieve a uniform distribution in the coating film, creating a micro-rough surface. The larger the surface particles, the greater the micro-roughness, resulting in lower gloss. In the production of matte coatings, lightweight materials such as precipitated calcium carbonate or talc are often used in large quantities, exceeding the critical pigment volume concentration and leading to issues like poor physical properties of the coating film, such as layering and hard settling. The use of matting agents can prevent these problems.   Matting agents are categorized into organic and inorganic types, with white silica being a prominent inorganic matting agent. This article focuses on the application of white silica matting agent in solvent-based wood coatings: High-Solids Coatings High-solids coatings have a high solid content and low volatile solvents, leading to increased matting agent usage and viscosity. The particle size of the matting agent becomes crucial, and it should be selected based on the dry film thickness. Choosing a matting agent with a small particle size may result in low matting efficiency, higher consumption, and issues like accumulation, whitening, and poor transparency. On the other hand, selecting a matting agent with a larger particle size can meet tactile requirements while achieving the desired matting effect. Clear Varnish Clear varnishes are primarily used to provide gloss to the surface. Matte clear varnishes achieve diffuse reflection by adding matting agents. Factors such as efficiency, particle size, transparency, anti-settling properties, dispersibility, and surface feel should be considered when determining the matting agent dosage. The white silica content in matting agents for coatings should be above 95%, with wax treatment recommended to prevent settling and blockage. Wax treatment enhances compatibility with solvent-based coating systems, improves scratch resistance, and enhances film slip, although it may slightly reduce matting efficiency and transparency. Colored Paints In colored paint systems, pigments and other fillers can provide matting effects, but excessive use may compromise the coating's mechanical and weathering properties. Introducing white silica matting agents, if selected appropriately, can partially replace some of the expensive gas-phase process matting agents, meeting product quality requirements while significantly reducing costs.   Product Recommend Silica Matting Agent Type 740 750 770 Specific surface area, m²/g 300-380 300-380 320-400 Heating loss（105° 2h）, % ≤5.0 ≤5.0 ≤8.0 Lgniting loss（1000° 2h）% ≤7.0 SiO2 (After igniting loss), % ≥99.0 pH（5% suspension） 5.0-7.0 DBP Absorption, cm³/g 2.00-3.50 Salt as NA2SO4, % ≤200 Whiteness ≥94.0 Pore Volume 2.0±0.2 Scraper Fineness ≤21 ≤23 ≤36
