Hydrophobic silica is a type of silica material that has been chemically modified to repel or be resistant to water. This modification alters the surface properties of silica nanoparticles, making them less prone to interacting with water molecules. The modification process typically involves treating the surface of the silica nanoparticles with hydrophobic compounds, such as alkylsilanes or fluorosilanes. These compounds form a hydrophobic layer on the surface of the silica particles, effectively blocking interactions with water molecules. Hydrophobic silica finds numerous applications across various industries. For example, it is used as an additive in coatings, paints, and sealants to improve water repellency and durability. In the pharmaceutical and food industries, hydrophobic silica can be used as an anti-caking agent to prevent clumping in powdered products. Additionally, it is utilized in rubber and plastic composites to enhance their water resistance and mechanical properties.

Hydrophilic silica is a type of silica material that exhibits a strong affinity for water. Unlike hydrophobic silica, which repels water, hydrophilic silica readily interacts with and absorbs water molecules. The surface of hydrophilic silica nanoparticles is typically functionalized with hydrophilic groups, such as hydroxyl (-OH) groups. These groups enable the silica particles to form hydrogen bonds with water molecules, promoting their dispersion and solubility in aqueous solutions. Hydrophilic silica has various applications across industries. In the pharmaceutical and cosmetic sectors, it is used as an excipient in formulations to improve the dispersibility and bioavailability of active ingredients. In chromatography, hydrophilic silica is employed as a stationary phase for separating polar compounds. It is also utilized in coatings, paints, and adhesives to enhance their rheological properties and adhesion to substrates.
Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments. Its appearance is white powder. Native particle size ranges from 5nm to 40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.

Modified silica sol refers to a type of colloidal solution where silica nanoparticles are suspended in a liquid medium, typically water. These silica nanoparticles are modified or functionalized with various organic or inorganic compounds to alter their surface properties and enhance their performance in different applications. The modification process can involve chemically bonding organic molecules to the surface of the silica particles, which can impart specific functionalities such as hydrophobicity, oleophobicity, or compatibility with certain polymers or solvents. Inorganic modifications may include incorporating metal oxides or other nanoparticles to enhance properties like catalytic activity or mechanical strength. Modified silica sols find widespread use in various industries such as coatings, adhesives, sealants, composites, and catalysts. They offer advantages like improved dispersion, adhesion, and compatibility, making them valuable additives in many formulations.
Talc is a hydrous Magnesium Silicate and its chemical composition would correspond to 63.5% Silica (Si02), 31.7% Magnesia (MgO) and 4.8% water (H20). Talc is an environmentally friendly alternative to chemicals for the Ultraviolet protection of crops reducing water pick-up and mud. In fertilizers, Talcs are outstanding coating agents. It improves fertilizer flow, reducing water pick-up, prevents caking, protecting from crystal bridge formation and reducing dust. Talc is a perfect carrier in feed pre-mixes and agricultural chemicals. Uses: Talc is hydrophobic in nature, meaning that it repels water. As a result, it is used as an anticaking agent in the formulation of fertilizers which prevents the formation of lumps or stickiness. Talc is used in both powdered and granular fertilizers where they make excellent coating agents that prevent fertilizer caking. In the production of animal feed, talc is employed as an anticaking and dispersing agent, and die lubricant. Talc is employed as a carrier in feed premixes and agricultural chemicals such as pesticides. Talc forms a barrier all over the fertilizer granules which limits water pick-up and stops the formation of hydrate crystal bridges allowing products to be stored longer. Talc is also inert and platy. Its smooth and flat lamellae cover each particle helping it to flow freely during fertilizer or feed production. it also protects against dust.
